No members mapped for type - CSV Helper

I am new to using CSVHelper and AutoMapper and am getting the following error when trying to:
public async Task<IActionResult> OnPostAsync()
{
if (BolCsv != null)
{
try
{
using (var reader = new StreamReader(BolCsv.OpenReadStream()))
using (var csvr = new CsvReader(reader, System.Globalization.CultureInfo.CurrentCulture))
{
csvr.Configuration.Delimiter = "\t";
csvr.Configuration.HeaderValidated = null;
csvr.Configuration.MissingFieldFound = null;
var bolDtos = csvr.GetRecords<BOLDto>().ToList();
var bols = _mapper.Map<IEnumerable<BOL>>(bolDtos);
await _context.SaveChangesAsync();
return RedirectToPage("./Index");
}
}
var bolDtos = csvr.GetRecords<BOLDto>();
Error: No members are mapped for type 'BOLDto'.
BOLDto:
{
public class BOLDto
{
[Name("BOLNumber")]
public int BOLNumber { get; set; }
[Name("ProductID")]
public int ProductID { get; set; }
[Name("ProductDescription")]
public string ProductDescription { get; set; }
etc...
}
}
BOL.cs:
{
public class BOL
{
public int BOLNumber { get; set; }
public int ProductId { get; set; }
public string ProductDescription { get; set; }
etc...
}
}
As I mentioned Im new to ASP.Net Core AutoMapper, and CSVHelper... how do I solve this issue?

It looks like your BOLDto class has properties, but that error message is the same as I would get if the class had fields instead of properties. So you might want to try CsvHelper.Configuration.MemberTypes.Fields. Also that must be an older version of CsvHelper you are using, because that is not how you would need to set up the configuration in the current version. But it should still work for you to add csvr.Configuration.MemberTypes = CsvHelper.Configuration.MemberTypes.Fields.
void Main()
{
var config = new MapperConfiguration(cfg => cfg.CreateMap<BOLDto, BOL>());
var _mapper = config.CreateMapper();
var csvConfig = new CsvConfiguration(CultureInfo.InvariantCulture)
{
Delimiter = "\t",
HeaderValidated = null,
MissingFieldFound = null,
MemberTypes = CsvHelper.Configuration.MemberTypes.Fields
};
using (var reader = new StringReader("BOLNumber\tProductID\tProductDescription\t\n1\t2\tMy Product"))
using (var csvr = new CsvReader(reader, csvConfig))
{
var bolDtos = csvr.GetRecords<BOLDto>().ToList();
var bols = _mapper.Map<IEnumerable<BOL>>(bolDtos);
}
}
public class BOLDto
{
[Name("BOLNumber")]
public int BOLNumber;
[Name("ProductID")]
public int ProductID;
[Name("ProductDescription")]
public string ProductDescription;
}
public class BOL
{
public int BOLNumber { get; set; }
public int ProductId { get; set; }
public string ProductDescription { get; set; }
}

Populating viewmodel array

What Am I doing wrong? In the code below (specifically on foreach), When I have more than one 'itens', just the last one will be on Itens array.
I am using a viewmodel array, as you can see below.
I would appreciate if you could give me a sample.
I created a repository class like this:
public async Task<PrintNFePedidoRoot> PedidoPrint(int idPedido)
{
using var db = new KeplerContext(_optionsBuilder);
var pedido = await db.Pedido.AsNoTracking()
.FirstOrDefaultAsync(m => m.IdPedido == idPedido);
var pedidoItens = await db.PedidoItens
.Where(i => i.IdPedido == idPedido)
.Include(p => p.IdProdutoNavigation)
.AsNoTracking().ToListAsync();
var pedidoPrint = new PrintNFePedidoRoot()
{
IdPedido = idPedido,
TotalValor = pedido.Val,
Desconto = 0,
Taxa = pedido.Tax,
TotalPagar = pedido.Tot,
};
var Itens = Array.Empty<PrintNFePedidoItens>();
foreach (PedidoItens i in pedidoItens)
{
if (i.IdProdutoMeia != null)
{
var produto = db.Produto
.AsNoTracking()
.First(p => p.IdProduto == i.IdProdutoMeia);
i.IdProdutoNavigation.Nome = i.IdProdutoNavigation.Nome + "/" + produto.Nome.Replace("Exp", "").Trim();
}
Itens = new[]
{
new PrintNFePedidoItens
{
IdProduto = i.IdProduto,
Nome = i.IdProdutoNavigation.Nome,
Valor = i.IdProdutoNavigation.Preco
}
};
}
pedidoPrint.Itens = Itens;
return pedidoPrint;
}
I created a viewModel class like these:
public class PrintNFePedidoRoot
{
[JsonProperty("id_pedido")]
public int IdPedido { get; set; }
[JsonProperty("total_valor")]
public int TotalValor { get; set; }
[JsonProperty("desconto")]
public int Desconto { get; set; }
[JsonProperty("taxa")]
public int Taxa { get; set; }
[JsonProperty("total_pagar")]
public int TotalPagar { get; set; }
[JsonProperty("pedido_itens")]
public PrintNFePedidoItens[] Itens { get; set; }
}
public class PrintNFePedidoItens
{
[JsonProperty("id_produto")]
public int IdProduto { get; set; }
[JsonProperty("nome")]
public string Nome { get; set; }
[JsonProperty("valor")]
public decimal Valor { get; set; }
}

Looks like you are assigning a new array with just one element to "Itens" instead to add values to the array.
Instead of this
Itens = new[]
{
new PrintNFePedidoItens
{
IdProduto = i.IdProduto,
Nome = i.IdProdutoNavigation.Nome,
Valor = i.IdProdutoNavigation.Preco
}
};
Try
Itens.Add(new PrintNFePedidoItens
{
IdProduto = i.IdProduto,
Nome = i.IdProdutoNavigation.Nome,
Valor = i.IdProdutoNavigation.Preco
});
Just be sure you are initializing correctly "Itens".

This way is working.
Instead of this:
var Itens = Array.Empty<PrintNFePedidoItens>();
I have changed to this:
var Itens = new List<PrintNFePedidoItens>();
Instead of this:
public class PrintNFePedidoRoot
{
...
[JsonProperty("pedido_itens")]
public PrintNFePedidoItens[] Itens { get; set; }
}
I have changed to this:
public class PrintNFePedidoRoot
{
...
[JsonProperty("pedido_itens")]
public List<PrintNFePedidoItens> Itens { get; set; }
}
So, I could used this:
Itens.Add(new PrintNFePedidoItens
{
IdProduto = i.IdProduto,
Nome = i.IdProdutoNavigation.Nome,
Valor = i.IdProdutoNavigation.Preco,
Qntd = i.Quantidade
});

Error while reading data from azure table storage

I'm writing a code to read values from a table storage. The code is similar to printing nodes in a tree level by level.
eg:
root
Level1child1 -> Level1child2 -> Level1child3
string tablename = "<table-name">;
string storageAccountName = "<storage-account-name";
var baseurl = #$"https://{storageAccountName}.table.core.windows.net/{tableName}()";
var sastoken = getAccountSASToken();
string filter = #"&$filter=PartitionKey%20eq%20'123'%20and%20RowKey%20eq%20'abc'";
baseurl = $"{baseurl}{sastoken}{filter}";
var data = HttpHelper.GetForOData(baseurl);
var responseData = data.Data.Replace(".", "_");
var odata = JsonConvert.DeserializeObject<ODataResponse>(responseData);
Queue<int> strQ = new Queue<int>();
Console.WriteLine(odata.value[0].Email);
strQ.Enqueue(odata.value[0].TreeNodeID);
while (strQ.Any())
{
var url = #$"https://{storageAccountName}.table.core.windows.net/{tableName}()";
var token = _tableStorageRepository.GetAccountSASToken();
filter = #"&$filter=ParentNodeId%20eq%20" + strQ.Peek();
url = $"{url}{token}{filter}";
data = HttpHelper.GetForOData(url);
responseData = data.Data.Replace(".", "_");
odata = JsonConvert.DeserializeObject<ODataResponse>(responseData);
foreach (var m in odata?.value)
{
Console.WriteLine(m.Email);
strQ.Enqueue(m.TreeNodeID);
}
strQ.Dequeue();
}
public class ODataResponse
{
public string odata_metadata { get; set; }
public List<ODatavalue> value { get; set; }
}
public class ODatavalue
{
public string odata_type { get; set; }
public string odata_id { get; set; }
public string odata_etag { get; set; }
public string odata_editLink { get; set; }
public string RowKey { get; set; }
public string Email { get; set; }
public int ParentNodeID { get; set; }
public int TreeNodeID { get; set; }
}
Code for HttpHelper class: https://github.com/xyz92/httphelper/blob/master/HttpHelper.cs
The first time when I ran this code, it only printed root node.
The second time when I ran this code, it printed root node and Level1child1 node.
For the next runs, it printed root node, Level1child1 node & Level1child2 node.
The last node Level1child3 node is getting printed very rarely on some runs.
What am I missing in this code?
UPDATE:
Sample responseData:
{
"odata_metadata": "https://<storage-account-name>_table_core_windows_net/$metadata#<table-name>",
"value": [{

How to encode text using File.WriteAllLines?

I was trying to make a txt file, then rename the extension to .json, I have the encoding step and the WriteAllLines step done, but how do I encode the text?(I have the string needed to write)
Here's the code
string[] lines = { "{", "\"version\": 1,", "\"schema_version\": 2,", "",
$"\"id\": \"{textBox14.Text}\",", "", $"\"title\": \"{textBox7.Text}\",",
$"\"title_localized\": \"{textBox18.Text}\",", "", $"\"artist\": \"{textBox6.Text}\",",
$"\"artist_localized\": \"{textBox8.Text}\",", $"\"artist_source\": \"{textBox9.Text}\",",
$"", $"\"illustrator\": \"{textBox10.Text}\",", $"\"illustrator_source\": \"{textBox11.Text}\",",
$"", $"\"charter\": \"{textBox13.Text}\",", $"", "\"music\": {",
$"\"path\": \"{textBox4.Text}\"", "}", "\"music_preview\": {", $"\"path\": \"{textBox5.Text}\"", "}",
"\"background\": {", $"\"path\": \"{open3.FileName}\"", "}",
"\"charts\": [", "{", "\"type\": \"easy\",", $"\"name\": \"{textBox15.Text}\",",
$"\"difficulty\": {numericUpDown1.Value},", $"\"path\": \"textBox1.Text\"", "},",
"{", "\"type\": \"hard\",", $"\"name\": \"{textBox16.Text}\",", $"\"difficulty\": {numericUpDown2.Value},",
$"\"path\": \"{textBox2.Text}\"", "},", $"]", $"", "}" };
Encoding utf8WithoutBom = new UTF8Encoding(true);
File.WriteAllLines($#"C:\Users\Public\Desktop\level files\{textBox14.Text}\level.json", lines);
It was supposed to be something like this:
https://cytoid.io/level.json

Short answer:
Change this:
File.WriteAllLines($#"C:\Users\Public\Desktop\level files\{textBox14.Text}\level.json", lines);
to this:
File.WriteAllLines($#"C:\Users\Public\Desktop\level files\{textBox14.Text}\level.json", lines, utf8WithoutBom);
Long answer:
You shouldn't be generating JSON like this; you should be using a dedicated serializer. With your current solution, if a user enters an invalid character, your JSON will immediately become invalid. So, as a solution you could use Newtonsoft's JSON.Net. Here is an example:
Class definitions
public class Item
{
public int Version { get; set; }
public int SchemaVersion { get; set; }
public string Id { get; set; }
public string Title { get; set; }
public string TitleLocalized { get; set; }
public string Artist { get; set; }
public string ArtistLocalized { get; set; }
public string ArtistSource { get; set; }
public string Illustrator { get; set; }
public string IllustratorSource { get; set; }
public string Charter { get; set; }
public ItemMusic Music { get; set; }
public ItemMusicPreview MusicPreview { get; set; }
public ItemBackground Background { get; set; }
public List<ItemChart> Charts { get; set; }
}
public class ItemMusic
{
public string Path { get; set; }
}
public class ItemMusicPreview
{
public string Path { get; set; }
}
public class ItemBackground
{
public string Path { get; set; }
}
public class ItemChart
{
public string Type { get; set; }
public string Name { get; set; }
public int Difficulty { get; set; }
public string Path { get; set; }
}
Object initialization and serialization
var item = new Item
{
Version = 1,
SchemaVersion = 2,
Id = textBox14.Text,
Title = textBox7.Text,
TitleLocalized = textBox18.Text,
Artist = textBox6.Text,
ArtistLocalized = textBox8.Text,
ArtistSource = textBox9.Text,
Illustrator = textBox10.Text,
IllustratorSource = textBox11.Text,
Charter = textBox13.Text,
Music = new ItemMusic
{
Path = textBox4.Text
},
MusicPreview = new ItemMusicPreview
{
Path = textBox5.Text
},
Background = new ItemBackground
{
Path = open3.FileName
},
Charts = new List<ItemChart>
{
new ItemChart
{
Type = "easy",
Name = textBox15.Text,
Difficulty = numericUpDown1.Value,
Path = textBox1.Text
},
new ItemChart
{
Type = "hard",
Name = textBox16.Text,
Difficulty = numericUpDown2.Value,
Path = textBox2.Text
}
}
};
var settings = new JsonSerializerSettings()
{
ContractResolver = new DefaultContractResolver
{
NamingStrategy = new SnakeCaseNamingStrategy()
}
};
var json = JsonConvert.SerializeObject(item, settings);
File.WriteAllText($#"C:\Users\Public\Desktop\level files\{textBox14.Text}\level.json", json, new UTF8Encoding(true));
You could also use an anonymous type instead of creating the full class definition, of course:
var item = new {
Version = 1,
SchemaVersion = 2,
Charts = new List<object>
{
new {
Type = "easy"
}
}
}
and then just serialize this.

How to fill mongo Db table by C# Driver?

I am not an expert of nosql but a year ago I created a mongodb table by using below code:
const string connectionString = "mongodb://localhost:27017";
// Create a MongoClient object by using the connection string
var client = new MongoClient(connectionString);
////Use the MongoClient to access the server
var database = client.GetDatabase("YUSUF");
////get mongodb collection
var collection = database.GetCollection("expressions");
var expression = new Expression { Id = Guid.NewGuid().ToString(),ExpressionSentence = "Test",Name = "yusuf",CreatedDate = DateTime.Now,Status = true };
collection.InsertOneAsync(expression);
public class Expression {
[BsonId]
public string Id { get; set; }
public string Name { get; set; }
public string ExpressionSentence { get; set; }
public bool Status { get; set; }
public DateTime CreatedDate { get; set; }
}
Today above codes is doing nothing now. Not working also not throwing any error. What am I doing wrong?

static void insert()
{
var connectionString = "mongodb://localhost:27017";
var client = new MongoClient(connectionString);
var database = client.GetDatabase("YUSUF");
var collection = database.GetCollection<Expression>("expressions");
var expression = new Expression { Id = Guid.NewGuid().ToString(),ExpressionSentence = "Test",Name = "yusuf",CreatedDate = DateTime.Now,Status = true };
collection.InsertOneAsync(expression);
}
public class Expression {
[BsonId]
public string Id { get; set; }
public string Name { get; set; }
public string ExpressionSentence { get; set; }
public bool Status { get; set; }
public DateTime CreatedDate { get; set; }
}
have to work with the latest C# MongoDB Driver.
MY METHOD
static void insert()
{
var connectionString = "mongodb://localhost:27017";
var client = new MongoClient(connectionString);
var database = client.GetDatabase("fairytale");
// var unicorns = database.GetCollection("unicorns");
var unicorns = database.GetCollection<BsonDocument>("unicorns");
int i = 0;
while (i < 5000)
{
var document = new BsonDocument
{
{"name",GenerateRandomUnicornName()},
{"horns",Random.Next(50)},
{"likes",new BsonArray{ "apple", "onion" }},
};
unicorns.InsertOneAsync(document);
i++;
}
}
