How to remove comma separated value from a string?

Question

I want to remove a comma separated value from the string..

suppose I have a string like this

string x=\"r, v, l, m\"

and i want to

Answer 1

Its just single line of code in many ways, two of them are below:

string x = "r,v,l,m";
string NewX = String.Join(",", from i in x.Split(',') where  i != String.Empty && i != "v" select i);

OR

string NewX = String.Join(",", x.Split(',').Select(i => i.Trim()).Where(i => i != String.Empty && i != "v"));

Answer 2

String input = "r, v, l, m, ";

string itemToReplace = "v, ";

string output = input.Replace(itemToReplace, string.Empty)

Answer 3

So you want to delete an item (or replace it with a nother value) and join the string again with comma without space?

string x = "r, v, l, m,";
string value = "v";
string[] allVals = x.TrimEnd(',').Split(new []{','}, StringSplitOptions.RemoveEmptyEntries);
// remove all values:
x = string.Join(",", allVals.Where(v => v.Trim() != value));
// or replace these values
x = string.Join(",", allVals.Select(v => v.Trim() == value ? "new value" : v));

Answer 4

Just do something like:

List<String> Items = x.Split(",").Select(i => i.Trim()).Where(i => i != string.Empty).ToList(); //Split them all and remove spaces
Items.Remove("v"); //or whichever you want
string NewX = String.Join(", ", Items.ToArray());

Answer 5

Not quite sure if this is what you mean, but this seems simplest and most readable:

        string x = "r, v, l, m";
        string valueToRemove = "r";
        var result = string.Join(", ", from v in x.Split(',')
                                       where v.Trim() != valueToRemove
                                       select v);

Edit: like Bob Sammers pointed out, this only works in .NET 4 and up.

Answer 6

public void string Remove(string allStuff, string whatToRemove)
{
  StringBuilder returnString = new StringBuilder();
  string[] arr = allStuff.Split('');
   foreach (var item in arr){
     if(!item.Equals(whatToRemove)){
     returnString.Append(item);
     returnString.Append(", "); 
    }
   }
  return returnString.ToString();
}
