Is there any possiblity to extract only the numbers from a GUID? I'm trying to achieve this because I don't want to display the GUID in a form, but the numbers within, which also are unique.
You can use IsDigit to get only the numbers
var guidstring = Guid.NewGuid().ToString("N");
var getNumbers = (from t in guidstring
where char.IsDigit(t)
select t).ToArray();
DEMO
public string GetNumbersFromGuid(Guid Item)
{
var result = string.Empty;
var guidArray = Item.ToString().ToCharArray();
int n;
foreach (var item in guidArray)
{
if (int.TryParse(item.ToString(), out n) == true)
{
result += item.ToString();
}
}
return result;
}
Call it like:
var MyValue = GetNumbersFromGuid(Guid.NewGuid());

I have a database column that is a text field, and this text field contains values that look like
I=5212;A=97920;D=20181121|I=5176;A=77360;D=20181117|I=5087;A=43975;D=20181109
and can vary sometimes to look like:
I=29;A=20009.34;D=20190712;F=300|I=29;A=2259.34;D=20190714;F=300
Where 'I' represents the invoice Id, 'A' the invoice amount, 'D' the date in YYYYMMDD format and 'F' the original foreign currency value if the invoice was from a foreign supplier.
I am fetching that column and binding it to a datagrid which has a button labelled "Show Amount". On button click, it fetches the selected row and splits the string to extract "A"
I need to fetch all the sections with A= within the column result... i.e
A=97920
A=77360
A=43975
Then sum them all together and display the result on a label.
I have tried splitting using '|' first, extracting the substring 'A=' then splitting it using ';' to get the amount after "=".
string cAlloc;
string[] amount;
string InvoiceTotal;
string SupplierAmount;
string BalanceUnpaid;
DataRowView dv = invoicesDataGrid.SelectedItem as DataRowView;
if (dv != null)
{
cAlloc = dv.Row.ItemArray[7].ToString();
InvoiceTotal = dv.Row.ItemArray[6].ToString();
if (invoicesDataGrid.Columns[3].ToString() == "0")
{
lblAmount.Foreground = Brushes.Red;
lblAmount.Content = "No Amount Has Been Paid Out to the Supplier";
}
else
{
amount = cAlloc.Split('|');
foreach (string i in amount)
{
string toBeSearched = "A=";
string code = i.Substring(i.IndexOf(toBeSearched) + toBeSearched.Length);
string[] res = code.Split(';');
SupplierAmount = res[0];
float InvTotIncl = float.Parse(InvoiceTotal, CultureInfo.InvariantCulture.NumberFormat);
float AmountPaid = float.Parse(SupplierAmount, CultureInfo.InvariantCulture.NumberFormat);
float BalUnpaid = InvTotIncl - AmountPaid;
BalanceUnpaid = Convert.ToString(BalUnpaid);
if (BalUnpaid == 0)
{
lblAmount.Content = "Amount Paid = " + SupplierAmount + " No Balance Remaining, Supplier Invoice Paid in Full";
}
else if (BalUnpaid < 0)
{
lblAmount.Content = "Amount Paid = " + SupplierAmount + " Supplier Paid an Excess of " + BalanceUnpaid;
}
else
{
lblAmount.Content = "Amount Paid = " + SupplierAmount + " You Still Owe the Supplier a Total of " + BalanceUnpaid; ;
}
}
}
But I am only able to extract A=43975, the very last "A=". Instead of all three, plus I have not figured out how to sum the strings. Somebody help... please.
Regex is prefered solution. Alternatively split, split and split.
var cAlloc = "I=29;A=20009.34;D=20190712;F=300|I=29;A=2259.34;D=20190714;F=300";
var amount = cAlloc.Split('|');
decimal sum = 0;
foreach (string i in amount)
{
foreach (var t in i.Split(';'))
{
var p = t.Split('=');
if (p[0] == "A")
{
var s = decimal.Parse(p[1], CultureInfo.InvariantCulture);
sum += s;
break;
}
}
}
var in1 = "I=5212;A=97920;D=20181121|I=5176;A=77360;D=20181117|I=5087;A=43975;D=20181109";
var in2 = "I=29;A=20009.34;D=20190712;F=300|I=29;A=2259.34;D=20190714;F=300";
var reg = #"A=(\d+(\.\d+)?)";
Regex.Matches(in1, reg).OfType<Match>().Sum(m => double.Parse(m.Groups[1].Value));
Regex.Matches(in2, reg).OfType<Match>().Sum(m => double.Parse(m.Groups[1].Value));
You're doing too much work for something like this. Here's a simpler solution using Regex.
If the invoice amount is always located as a second value in the set you can access it directly by index after split:
var str = "I=5212;A=97920;D=20181121|I=5176;A=77360;D=20181117|I=5087;A=43975;D=20181109";
var invoices = str.Trim().Split(new[] { '|' }, StringSplitOptions.RemoveEmptyEntries);
var totalSum = 0M;
foreach (var invoice in invoices)
{
var invoiceParts = invoice.Split(new[] { ';' }, StringSplitOptions.RemoveEmptyEntries);
var invoiceAmount = decimal.Parse(invoiceParts[1].Trim().Substring(2));
totalSum += invoiceAmount;
}
Otherwise, you can use a little more "flexible" solution like this:
var str = "I=5212;A=97920;D=20181121|I=5176;A=77360;D=20181117|I=5087;A=43975;D=20181109";
var invoices = str.Trim().Split(new[] { '|' }, StringSplitOptions.RemoveEmptyEntries);
var totalSum = 0M;
foreach (var invoice in invoices)
{
var invoiceParts = invoice.Split(new[] { ';' }, StringSplitOptions.RemoveEmptyEntries);
var invoiceAmount = decimal.Parse(invoiceParts.First(ip => ip.Trim().ToLower().StartsWith("a=")).Substring(2));
totalSum += invoiceAmount;
}
Import the input: "Deserialisation"
With the following given input, we have a list of object with property name I,A, and D.
var input = "I=5212;A=97920;D=20181121|I=5176;A=77360;D=20181117|I=5087;A=43975;D=20181109";
Give this simple class:
public class inputClass
{
public decimal I { get; set; }
public decimal A { get; set; }
public decimal D { get; set; }
}
Parsing it will look like:
var inputItems =
input.Split('|')
.Select(
x =>
x.Split(';')
.ToDictionary(
y => y.Split('=')[0],
y => y.Split('=')[1]
)
)
.Select(
x => //Manual parsing from dictionary to inputClass.
//If dictionary Key match an object property we could use something more generik.
new inputClass
{
I = decimal.Parse(x["I"], CultureInfo.InvariantCulture.NumberFormat),
A = decimal.Parse(x["A"], CultureInfo.InvariantCulture.NumberFormat),
D = decimal.Parse(x["D"], CultureInfo.InvariantCulture.NumberFormat),
}
)
.ToList();
It look complexe? lets give the inputClass the responsability to initialise it self based on string
PropertyName=Value[; PropertyName=Value] :
public inputClass(string input, NumberFormatInfo numberFormat)
{
var dict = input
.Split(';')
.ToDictionary(
y => y.Split('=')[0],
y => y.Split('=')[1]
);
I = decimal.Parse(dict["I"], numberFormat);
A = decimal.Parse(dict["A"], numberFormat);
D = decimal.Parse(dict["D"], numberFormat);
}
Then the parsing is simple:
var inputItems = input.Split('|').Select(x => new inputClass(x, CultureInfo.InvariantCulture.NumberFormat));
Once we have a more useable Structure a List of object We can easly compute Sum, Avg, Max, Min:
var sumA = inputItems.Sum(x => x.A);
Producing the output: "Serialisation"
In order to process the input we will define an object like similar to the Input
public class outputClass
{
public decimal I { get; set; }
public decimal A { get; set; }
public decimal D { get; set; }
public decimal F { get; set; }
The Class should be able to produce the String PropertyName=Value[; PropertyName=Value], :
public override string ToString()
{
return $"I={I};A={A};D={D};F={F}";
}
Then producing and string "serialisation" after computing the ListOutput based on the List input:
//process The input into the output.
var outputItems = new List<outputClass>();
foreach (var item in inputItems)
{
// compute things to be able to create the nex output item
item.A++;
outputItems.Add(
new outputClass { A = item.A, D = item.D, I = item.I, F = 42 }
);
}
// "Serialisation"
var outputString = String.Join("|", outputItems);

Long story short:
Define a class with the property you will use/display.
Add a constructor that take a string like "I=5212;A=97920;D=20181121"
nb: the String may contain property that will not be map to the object
Override the ToString(), so It can easly produce it's serialisation.
nb: Property and value that are not stored in the object will not be in the serialisation result.
Now You simply have to split on your line/object separator "|" and you are ready to go using real object, not having to care about that weird string anymore.
PS:
There was a little missunderstand about your 2 type of inputs, I mentally saw them as input, output. Dont mind those name. It can be the same class. It doens't change anything in this answer.
I want to count all the characters in my list to see if I surpass the maxvalue of MaxJsonLength.
This is my controller where I have a list with products.
public JsonResult GetAllProducts()
{
List<ProductNew> allProducts = new List<ProductNew>();
var shopIdOfTheDay = 2;
allProducts = _db.Products
.Where(p => p.Category.ShopId == shopIdOfTheDay && p.Availability)
.OrderBy(p => p.Description)
.ToList();
//count the characters in the list here
int total = 0;
foreach (var value in allProducts)
{
string s = value.ToString();
int i;
i = s.Length;
total = total += i;
Console.WriteLine(total);
}
return new JsonResult { Data = allProducts, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
}
but the foreach loop is not working, because every string value is 109 characters long and that aint right.
If I break ath value.ToString is see that the value is +
{System.Data.Entity.DynamicProxies.ProductNew_7F6B12BDD7841029155EF84C6372688579A97D5AA4EA2378712AC64A67B25290} SeashellBrawlCorvee.Models.ProductNew {System.Data.Entity.DynamicProxies.ProductNew_7F6B12BDD7841029155EF84C6372688579A97D5AA4EA2378712AC64A67B25290}
So that aint right. There are multiple values in value, so that proberly why I cant cast it to String?
I tried doing an extra foreach. Like:
foreach (var value2 in value) {
string s1 = value2.ToString();
int i1;
i1 = s2.Length;
total = total += i1;
Console.WriteLine(total);
}
Something like this, but thats not working to because I get an error: foreach statement cannot operate on vairables of type 'PRoductNew'because 'ProductNew' does not contain a public definition for 'GetEnumerator'
So what to do?
Check string s = value.ToString();, the content of s may not be the result you want.
Because value is a class which is from ProductNew class, you can't get content through .ToString() method. If you want to count all characters, you should count every content of property in class, like this:
foreach (var value in allProducts)
{
string ID = value.ID.ToString();
string Category = value.Category.ToString();
string Description = value.Description.ToString();
total += (ID.Length + Category.Length + Description.Length);
Console.WriteLine(total);
}
I am trying to return that data from the foreach "hostedId" Can someone help?
public static string GetHostedRecordSet()
{
var request = new ListHostedZonesRequest()
{
MaxItems = "1"
};
var list = client.ListHostedZones(request);
foreach (var hostedId in list.HostedZones)
{
Console.WriteLine("\n Hosted ID is:");
Console.Write(hostedId.Id);
}
return hostedId;
}
It depends. If you want to return the first element:
return list.HostedZones.First().Id; // Not in a loop!
If you want to return several items, change the signature of the method:
public static IEnumerable<string> GetHostedRecordSet()
{
var request = new ListHostedZonesRequest()
{
MaxItems = "1"
};
var list = client.ListHostedZones(request);
return list.HostedZones
.Select(z => z.Id);
}
If you want to return all values as a single string you can concatenate them with a delimiter, such as ',':
public static string GetHostedRecordSet()
{
var request = new ListHostedZonesRequest()
{
MaxItems = "1"
};
var list = client.ListHostedZones(request);
StringBuilder result = new StringBuilder();
foreach (var hostedId in list.HostedZones)
{
result.Append(hostedId.Id).Append(",");
}
return result.ToString(0, Math.Max(0, result.Length - 1);
}
I want to loop through three List<string>. I'm sending ajax request containing 3 parameter as Array.
This is my WebMethod.
public string saveEachTask(string imageData, string desc, string tid)
{
var imglist = imageData.Split(',').ToList();
var desclist = desc.Split(',').ToList();
var idlist = tid.Split(',').ToList();
// here i want a foreach loop for above three list
return "Saved Succesfully";
}
Edit: in loop how can I identity which string is for img, desc and id
Any Help appreciated.
Perhaps something like this:
foreach (var list in new[] {imglist, desclist, idlist})
{
foreach (var s in list)
{
}
}
Use one loop and each iteration process each list.
public string saveEachTask(string imageData, string desc, string tid)
{
var imglist = imageData.Split(',').ToList();
var desclist = desc.Split(',').ToList();
var idlist = tid.Split(',').ToList();
int maxLength = Math.Max(imglist.Count, Math.Max(desclist.Count, idlist.Count));
for (int i = 0; i < maxLength; ++i)
{
string imgItem = (i < imglist.Count ? imglist[i] : null);
string descItem = (i < desclist.Count ? desclist[i] : null);
string idItem = (i < idlist.Count ? idlist[i] : null);
// TODO: Process imgItem, descItem, idItem
}
return "Saved Succesfully";
}
If you need to handle everything the same way in your loop, you could try:
foreach(var s in imglist.Union(desclist.Union(idlist)))
{
// do something with the string
}
Building a string for post request in the following way,
var itemsToAdd = sl.SelProds.ToList();
if (sl.SelProds.Count() != 0)
{
foreach (var item in itemsToAdd)
{
paramstr = paramstr + string.Format("productID={0}&", item.prodID.ToString());
}
}
after I get resulting paramstr, I need to delete last character & in it
How to delete last character in a string using C#?
Personally I would go with Rob's suggestion, but if you want to remove one (or more) specific trailing character(s) you can use TrimEnd. E.g.
paramstr = paramstr.TrimEnd('&');
build it with string.Join instead:
var parameters = sl.SelProds.Select(x=>"productID="+x.prodID).ToArray();
paramstr = string.Join("&", parameters);
string.Join takes a seperator ("&") and and array of strings (parameters), and inserts the seperator between each element of the array.
string source;
// source gets initialized
string dest;
if (source.Length > 0)
{
dest = source.Substring(0, source.Length - 1);
}
Try this:
paramstr.Remove((paramstr.Length-1),1);
I would just not add it in the first place:
var sb = new StringBuilder();
bool first = true;
foreach (var foo in items) {
if (first)
first = false;
else
sb.Append('&');
// for example:
var escapedValue = System.Web.HttpUtility.UrlEncode(foo);
sb.Append(key).Append('=').Append(escapedValue);
}
var s = sb.ToString();
string str="This is test string.";
str=str.Remove(str.Length-1);
It's better if you use string.Join.
class Product
{
public int ProductID { get; set; }
}
static void Main(string[] args)
{
List<Product> products = new List<Product>()
{
new Product { ProductID = 1 },
new Product { ProductID = 2 },
new Product { ProductID = 3 }
};
string theURL = string.Join("&", products.Select(p => string.Format("productID={0}", p.ProductID)));
Console.WriteLine(theURL);
}
It's good practice to use a StringBuilder when concatenating a lot of strings and you can then use the Remove method to get rid of the final character.
StringBuilder paramBuilder = new StringBuilder();
foreach (var item in itemsToAdd)
{
paramBuilder.AppendFormat(("productID={0}&", item.prodID.ToString());
}
if (paramBuilder.Length > 1)
paramBuilder.Remove(paramBuilder.Length-1, 1);
string s = paramBuilder.ToString();
paramstr.Remove((paramstr.Length-1),1);
This does work to remove a single character from the end of a string. But if I use it to remove, say, 4 characters, this doesn't work:
paramstr.Remove((paramstr.Length-4),1);
As an alternative, I have used this approach instead:
DateFrom = DateFrom.Substring(0, DateFrom.Length-4);
Add a StringBuilder extension method.
public static StringBuilder RemoveLast(this StringBuilder sb, string value)
{
if(sb.Length < 1) return sb;
sb.Remove(sb.ToString().LastIndexOf(value), value.Length);
return sb;
}
then use:
yourStringBuilder.RemoveLast(",");
