TrimEnd() not working

I want to trim the end off a string if it ends in ", ". That's a comma and a space.

I've tried TrimEnd(', '), but this doesn't work. It has to be only if the string ends this way, so I can't just use .Remove to remove the last two characters. How can I do it?

string txt = " testing, ,  ";
txt = txt.TrimEnd(',',' ');   // txt = "testing"

This uses the overload TrimEnd(params char[] trimChars). You can specify 1 or more chars that will form the set of chars to remove. In this case comma and space.

The catch is that mystring.Trim(',') will only work if you reassign it to the string itself like this:

mystring = mystring.Trim(',')

 if (model != null && ModelState.IsValid)
                {
                    var categoryCreate = new Categories
                    {
                        CategoryName = model.CategoryName.TrimStart().TrimEnd(),
                        Description = model.Description.TrimStart().TrimEnd()
                    };
                    _CategoriesService.Create(categoryCreate);
                }

TrimStart().TrimEnd() == Left Trim and Right Trim

"value, ".Trim().TrimEnd(",") should also work.

This should work:

string s = "Bar, ";

if (s.EndsWith(", "))
    s = s.Substring(0, s.Length - 2);

EDIT

Come to think of it, this would make a nice extension method:

public static String RemoveSuffix(this string value, string suffix)
{
    if (value.EndsWith(suffix))
        return value.Substring(0, value.Length - suffix.Length);

    return value;
}

Try this:

string someText = "some text, ";
char[] charsToTrim = { ',', ' ' };
someText = someText.TrimEnd(charsToTrim);

Works for me.
