We Keep Coding

Unification of the 2 methods

I need some help. I need to combine these two methods into one and I can't figure out how.
I tried with an IF statement (we checked if employeeMark is NullOrEmpty, we use the first logic and if it's not, the second logic) but it's just duplicated code in one method instead of two.
This is the first method :
private async Task<ProcessedContractsIdentifiers> GetContractsIdentifiersByContractsCodes(List<ImportableContractIdentifier> importableContractsIdentifiers)
{
var errors = new List<ContractImportValidationErrorDto>();
foreach (var contract in importableContractsIdentifiers.Where(contract => string.IsNullOrWhiteSpace(contract.ContractCode)))
{
errors.Add(new ContractImportValidationErrorDto
{
ValidatedCode = string.Empty,
Line = contract.RowNumber,
ErrorCode = ContractImportValidationErrorCode.ContractCodeIsRequired
});
}
var contractsCodes = importableContractsIdentifiers.ConvertAll(x => x.ContractCode);
contractsCodes = contractsCodes.Where(x => !string.IsNullOrWhiteSpace(x)).ToList();
var contractsSignatures = await GetContractsSignaturesByContractsCodes(contractsCodes);
var unresolvedContracts = contractsCodes.Except(contractsSignatures.Select(cs => cs.Code)).ToHashSet();
foreach (var c in unresolvedContracts)
{
errors.Add(new ContractImportValidationErrorDto
{
ValidatedCode = c,
ErrorCode = ContractImportValidationErrorCode.InvalidContractCode
});
}
return new ProcessedContractsIdentifiers
{
IdentificationMethod = ContractIdentificationMethod.ByContractCode,
IdentifiedContractsSignatures = contractsSignatures,
NonIdentifiableContracts = errors
};
}
And this is the second method :
private async Task<ProcessedContractsIdentifiers> GetContractsIdentifiersByEmployeesMarks(List<ImportableContractIdentifier> importableContractsIdentifiers)
{
const int withSingleContract = 1;
var errors = new List<ContractImportValidationErrorDto>();
foreach (var contract in importableContractsIdentifiers.Where(contract => string.IsNullOrWhiteSpace(contract.EmployeeMark)))
{
errors.Add(new ContractImportValidationErrorDto
{
ValidatedCode = string.Empty,
Line = contract.RowNumber,
ErrorCode = ContractImportValidationErrorCode.EmployeeMarkIsRequired
});
}
var employeesMarks = importableContractsIdentifiers.Select(x => x.EmployeeMark).Where(x => !string.IsNullOrWhiteSpace(x)).ToHashSet();
var contractsSignatures = await GetContractsSignaturesByEmployeeMark(employeesMarks);
var contractsGroupedByEmployeeMark = contractsSignatures.GroupBy(x => x.EmployeeMark);
foreach (var contracts in contractsGroupedByEmployeeMark.Where(x => x.ToList().Count != withSingleContract))
{
errors.Add(new ContractImportValidationErrorDto
{
ValidatedCode = contracts.Key,
ErrorCode = ContractImportValidationErrorCode.EmployeeMarkWithMultipleContracts
});
}
var unresolvedMarks = employeesMarks.Except(contractsSignatures.Select(cs => cs.EmployeeMark)).ToHashSet();
foreach (var eMark in unresolvedMarks)
{
errors.Add(new ContractImportValidationErrorDto
{
ValidatedCode = eMark,
ErrorCode = ContractImportValidationErrorCode.InvalidEmployeeMark
});
}
return new ProcessedContractsIdentifiers
{
IdentificationMethod = ContractIdentificationMethod.ByEmployeeMark,
IdentifiedContractsSignatures = contractsSignatures,
NonIdentifiableContracts = errors
};
}

Use Enum as parameter, so according to its value you can write code blocks.
public Enum IOMode
{
In=0,
Out=1
}
public void CalculateAttendance(List<Log> lstLog, IOMode eIOMode)
{
if(eIOMode==IOMode.In)
{}
else
{ }
}
call CalculateAttendance(lstLog, IOMode.In) etc

Adding a wall with an opening Xbim

I am looking to adjust the template project to add an opening for the door so the door will be flush with the wall system instead of appearing embedded in the skin of the wall any help would be very appreciated.

Loop through dataset by row number

I have a online dataset that I am looping through to save it to a sqlite database. It works well, however the 'count' in which it is sequentially looping through is based on the ID column, however there are instances where the IDs (for the category that I am filtering on) are not sequential. I'd rather loop through row number or similar if possible - but I can't seem to find a way to do it. Below is my code:
Note the count starts at 793 because this is the ID of the first 'surface' categorised record
private async void updateAssetRegisterLocal()
{
try
{
var current = Connectivity.NetworkAccess;
if (current != NetworkAccess.Internet)
{
await DisplayAlert("No Internet Connectivity", "Move to a location with mobile coverage and try again", "OK");
}
else
{
UserDialogs.Instance.ShowLoading();
HttpClient client = new HttpClient();
var response = await client.GetStringAsync("https://XXXX.azurewebsites.net/api/assets");
var onlineAssets = JsonConvert.DeserializeObject<List<AssetRegister>>(response);
var assetsPrelim = onlineAssets
.Where(w => w.Asset_Category == "Surface")
.OrderBy(d => d.ID)
.ToList();
;
using (SQLiteConnection conn = new SQLiteConnection(App.FilePath))
{
try
{
conn.DropTable<AssetRegister>();
}
catch
{
await DisplayAlert("Unsuccessful", "Can't Access", "OK");
}
}
for (int count = 793; count <= (assetsPrelim.Count + 793); count++)
{
var assets = assetsPrelim.Where(x => x.ID == count);
var id = assets.Select(l => l.ID).FirstOrDefault();
var asset_ID = assets.Select(l => l.Asset_ID).FirstOrDefault();
var road_ID = assets.Select(l => l.Road_ID).FirstOrDefault();
var segmentString = assets.Select(l => l.AssetSegmentString).FirstOrDefault();
var hierarchy = assets.Select(l => l.Road_Hierarchy).FirstOrDefault();
var assetCategory = assets.Select(l => l.Asset_Category).FirstOrDefault();
var lat = assets.Select(l => l.Lat).FirstOrDefault();
var inspectionDue = assets.Select(l => l.Inspection_Due).FirstOrDefault();
var lon = assets.Select(l => l.Lon).FirstOrDefault();
var stdRoadId = assets.Select(l => l.StdRoadID).FirstOrDefault();
var assetType = assets.Select(l => l.Asset_Type).FirstOrDefault();
var inspectionDate = assets.Select(l => l.Last_Inspection_Date).FirstOrDefault();
using (SQLiteConnection con = new SQLiteConnection(App.FilePath))
{
con.CreateTable<AssetRegister>();
var assetsLocal = con.Table<AssetRegister>().ToList();
int arlID = assetsLocal.Count + 1;
AssetRegister arl = new AssetRegister()
{
ID = id,
Asset_ID = asset_ID,
Asset_Type = assetType,
Asset_Category = assetCategory,
Road_ID = road_ID,
Road_Hierarchy = hierarchy,
AssetSegmentString = segmentString,
Inspection_Due = inspectionDue,
StdRoadID = stdRoadId,
Lat = lat,
Lon = lon,
Last_Inspection_Date = inspectionDate,
};
using (SQLiteConnection conn = new SQLiteConnection(App.FilePath))
{
conn.CreateTable<AssetRegister>();
int rowsAdded = conn.Insert(arl);
conn.Close();
}
}
}
await DisplayAlert("Success", "Asset Register Updated on Device", "OK");
UserDialogs.Instance.HideLoading();
}
}
catch
{
await DisplayAlert("Error", "Could not get data - Report to System Adminstrator", "OK");
UserDialogs.Instance.HideLoading();
}
}

It looks like you can loop simply iterating using foreach
Instead of
for (int count = 793; count <= (assetsPrelim.Count + 793); count++)
{
var assets = assetsPrelim.Where(x => x.ID == count);
var id = assets.Select(l => l.ID).FirstOrDefault();
var asset_ID = assets.Select(l => l.Asset_ID).FirstOrDefault();
var road_ID = assets.Select(l => l.Road_ID).FirstOrDefault();
var segmentString = assets.Select(l => l.AssetSegmentString).FirstOrDefault();
var hierarchy = assets.Select(l => l.Road_Hierarchy).FirstOrDefault();
var assetCategory = assets.Select(l => l.Asset_Category).FirstOrDefault();
var lat = assets.Select(l => l.Lat).FirstOrDefault();
var inspectionDue = assets.Select(l => l.Inspection_Due).FirstOrDefault();
var lon = assets.Select(l => l.Lon).FirstOrDefault();
var stdRoadId = assets.Select(l => l.StdRoadID).FirstOrDefault();
var assetType = assets.Select(l => l.Asset_Type).FirstOrDefault();
var inspectionDate = assets.Select(l => l.Last_Inspection_Date).FirstOrDefault();
...
you can have
foreach (var asset in assetsPrelim)
{
var id = asset.ID;
var asset_ID = asset.Asset_ID;
var road_ID = assets.Road_ID;
var segmentString = asset.AssetSegmentString;
var hierarchy = asset.Road_Hierarchy;
var assetCategory = asset.Asset_Category;
var lat = asset.Lat;
var inspectionDue = asset.Inspection_Due;
var lon = asset.Lon;
var stdRoadId = asset.StdRoadID;
var assetType = asset.Asset_Type;
var inspectionDate = asset.Last_Inspection_Date;
...

Simply use foreach() instead of for() loop,
for (var asset in assetsPrelim)
{
var id = asset.Id;
var asset_ID = asset.Asset_ID;
var road_ID = assets.Road_ID;
//...
}

Push multiple objects with dynamic data into a DTO and return it

So I'm trying to use a DTO to reshape and return data, it's not working because I'm trying to push in an array of objects (as an IQueryable - which I don't think works) into the DTO, I'm also trying to push in dynamic data into one of the properties, as seen below in the 'hasCurrentUserLiked' property. I need to figure out How to change the objects from IQueryable, into actual objects so they can all be pushed into the DTO and the dynamic data can be worked out.
This is the code
public async Task<PagedList<UserPhoto>> GetSpecificFeed(UserParams userParams)
{
var user = _context.Users.FirstOrDefault(x => x.Username == userParams.u);
var userId = user.Id;
var photos = _context.UserPhotos;
var followerIds = _context.Follows.Where(x => x.FollowerId == userId).Select(x => x.FollowingId).ToList();
var feeds = _context.UserPhotos.Where(x => followerIds.Contains(x.UserId)).OrderByDescending(x => x.DateAdded);
// this doesn't work because 'feeds' is an IQueryable, not an object
var like = await hasCurrentUserLiked(user.Id, feeds.id);
// this has the same problem as above
var feedsToReturn = new FeedsForReturnDto
{
Id = feeds.Id,
PhotoUrl = feeds.photoUrl,
Username = feeds.Username,
Description = feeds.Description,
DateAdded = feeds.DateAdded,
IsImage = feeds.IsImage,
hasCurrentUserLiked = like,
Likes = feeds.Likes
}
return await PagedList<UserPhoto>.CreateAsync(feedsToReturn, userParams.PageNumber, userParams.PageSize);
}
I thought that I might be able to get each image.id in a similar way the 'followerIds' are worked out but I couldn't figure out how to get this to work
[EDIT]
As per Enas Osamas answer, I've changed the code to this and I've debugged it, feedsToReturn has the correct info, so it is doing what its supposed to do. The problem I'm having now is that I'm unable to return it as it can't convert the IEnumerable to an IQueryable. I tried adding an explicit cast but that didn't work, I also tried removing the PagedList, and replacing the type to but this didn't work. My is an IQueryable which might be the problem, I tried changing that to an IEnumerable but this would mess up the code in other places.
This is my new code (still returning 'feeds' instead of 'feedsToReturn', will change when it works)
public async Task<PagedList<UserPhoto>> GetSpecificFeed(UserParams userParams)
{
var user = _context.Users.FirstOrDefault(x => x.Username == userParams.u);
var userId = user.Id;
var photos = _context.UserPhotos;
var followerIds = _context.Follows.Where(x => x.FollowerId == userId).Select(x => x.FollowingId).ToList();
var feeds = _context.UserPhotos.Where(x => followerIds.Contains(x.UserId)).OrderByDescending(x => x.DateAdded);
var feedToReturn = feeds.AsEnumerable().Select(feed => new FeedsForReturnDto
{
Id = feed.Id,
PhotoUrl = feed.photoUrl,
Username = feed.Username,
Description = feed.Description,
DateAdded = feed.DateAdded,
IsImage = feed.IsImage,
hasCurrentUserLiked = hasCurrentUserLiked(user.Id, feed.Id),
Likes = feed.Likes
});
return await PagedList<UserPhoto>.CreateAsync(feeds, userParams.PageNumber, userParams.PageSize);
}
I also tried changing some of the types around and this is what I came up with. The problem here is this:
'System.Collections.Generic.IEnumerable<cartalk.api.Dtos.feeds.FeedsForReturnDto>' to 'System.Linq.IQueryable<System.Collections.IEnumerable>'
and this problem is with the 'feedsToReturn' in the last line
public async Task<PagedList<IEnumerable>> GetSpecificFeed(UserParams userParams)
{
var user = _context.Users.FirstOrDefault(x => x.Username == userParams.u);
var userId = user.Id;
var photos = _context.UserPhotos;
var followerIds = _context.Follows.Where(x => x.FollowerId == userId).Select(x => x.FollowingId).ToList();
var feeds = _context.UserPhotos.Where(x => followerIds.Contains(x.UserId)).OrderByDescending(x => x.DateAdded);
var feedToReturn = feeds.AsEnumerable().Select(feed => new FeedsForReturnDto
{
Id = feed.Id,
PhotoUrl = feed.photoUrl,
Username = feed.Username,
Description = feed.Description,
DateAdded = feed.DateAdded,
IsImage = feed.IsImage,
hasCurrentUserLiked = hasCurrentUserLiked(user.Id, feed.Id),
Likes = feed.Likes
});
return await PagedList<IEnumerable>.CreateAsync(feedToReturn, userParams.PageNumber, userParams.PageSize);
}
PagedList code
public static async Task<PagedList<T>> CreateAsync(IQueryable<T> source,
int pageNumber, int pageSize)
{
var count = await source.CountAsync();
var items = await source.Skip((pageNumber - 1) * pageSize).Take(pageSize).ToListAsync();
return new PagedList<T>(items, count, pageNumber, pageSize);
}
[EDIT]
This is the hasCurrentUserLiked function, it works here
public bool checkCurrentUserLiked(int currentUserId, int imageId)
{
var doesCurrentUserLike = _context.PhotoLikes.Where(x => x.LikerId == currentUserId && x.ImageId == imageId);
var value = true;
if (doesCurrentUserLike == null)
{
value = false;
}
else
{
value = true;
}
return value;
}

You can try something like
feeds.AsEnumerable().Select(feed => new FeedsForReturnDto
{
Id = feed.Id,
PhotoUrl = feed.photoUrl,
Username = feed.Username,
Description = feed.Description,
DateAdded = feed.DateAdded,
IsImage = feed.IsImage,
hasCurrentUserLiked = hasCurrentUserLiked(user.Id, feed.id),
Likes = feed.Likes
});
This would return an IEnumerable containing all the feeds mapped to your DTO after being enumerated to avoid performing operations against the database
[EDIT]
you can maybe do a left join with the _context.PhotoLikes.
Like this
feeds.GroupJoin(_context.PhotoLikes,
f => new { Id = f.Id, UserId = user.Id },
p => new { Id = p.ImageId, UserId = p.LikerId },
(f, p) => new { feed = f, photoLike = p })
.SelectMany(f => f.photoLike.DefaultIfEmpty(),
(f, p) => new FeedsForReturnDto
{
Id = f.feed.Id,
PhotoUrl = f.feed.photoUrl,
Username = f.feed.Username,
Description = f.feed.Description,
DateAdded = f.feed.DateAdded,
IsImage = f.feed.IsImage,
hasCurrentUserLiked = p != null,
Likes = feed.Likes
});
Just note that in this part
f => new { Id = f.Id, UserId = user.Id },
p => new { Id = p.ImageId, UserId = p.LikerId },
the datatypes of properties in both objects must match or it won't compile

How to get Bitcoin Private Key from an ExtPrivKey using NBitcoin

So, I am trying to send some money over using NBitcoin, there is a step where i am failing and that is creating de bitcoin secret to sign the transaction, I have the address, and the ExtPrivKey but i haven't gotten any luck signing it, any recommendation, this is my code below.
var priv = mbwallet.SelectedWallet.PrivateKeys[0].ToWif();
//var ool = new BitcoinSecret(base58, App.Network);
var privkey = mbwallet.SelectedWallet.PrivateKeys[0].PrivateKey.GetBitcoinSecret(App.Network).ToWif();
var key = Key.Parse(privkey, App.Network);
var keysT = key.GetWif(App.Network);
//var myaddress = mbwallet.SelectedWallet.PrivateKeys[0].PrivateKey.PubKey.GetAddress(App.Network);
var myaddress = mbwallet.SelectedWallet.CurrentAddress;
string address = Address.Text;
var destination = BitcoinAddress.Create(address, App.Network);
decimal value = Convert.ToDecimal(Value.Text);
var coins2 = GetCoins(value);
TransactionBuilder txBuilder = new TransactionBuilder();
var tx = txBuilder.AddCoins(coins2)
.AddKeys(keysT)
.SetChange(myaddress)
.Send(destination, new Money(value, MoneyUnit.BTC))
.SendFees("0.0002");
//.BuildTransaction(true);
var tx2 = txBuilder.BuildTransaction(true);
//Console.WriteLine(txBuilder.Verify(tx));
var hello = tx2.ToHex();
var txRepo = new NoSqlTransactionRepository();
//txRepo.Put(tx.GetHash(), tx);
//Assert(txBuilder.Verify(tx)); //check fully signed
List<ICoin> GetCoins(decimal sendAmount)
{
//var mbwallet = (root.DataContext as MainWindowViewModel);
var amountMoney = new Money(sendAmount, MoneyUnit.BTC);
var client = new QBitNinjaClient(App.Network);
var txInAmount = Money.Zero;
var coins1 = new List<ICoin>();
foreach (var balance in client.GetBalance(mbwallet.SelectedWallet.CurrentAddress,//MBWallet.Wallet.Address,
true).Result.Operations)
{
var transactionId = balance.TransactionId;
var transactionResponse =
client.GetTransaction(transactionId).Result;
var receivedCoins = transactionResponse.ReceivedCoins;
foreach (Coin coin in receivedCoins)
{
if (coin.TxOut.ScriptPubKey ==
mbwallet.SelectedWallet.CurrentAddress.ScriptPubKey)//MBWallet.Wallet.BitcoinPrivateKey.ScriptPubKey) // this may not be necessary
{
coins1.Add(coin);
txInAmount += (coin.Amount as Money);
}
}
}
return coins1;
}

For what I see in the code you already add the private key to the builder so basically you only need to sign , something like this
Transaction signed = txBuilder.SignTransaction(tx2);
