How can I do this it is not working on this.
gradeName = cellGradeValue.Value2.ToString().Trim(80);

I should trim the after spaces?

'NO.2 CANADA WESTERN AMBER DURUM (15.1) '

trim the rest of the spaces.

I don't think trim 80 will work.

Here we go again. I replaced the literal number 80 with the parameter length. This should solve your problem.

/// <summary>
/// Removes the trailing characters to the number
/// specified by <paramref name="length"/>.
/// </summary>
public string TruncateString(string s, int length)
{
      int removeStartIndex = s.Length - length;
 
      if(removeStartIndex <= 0)
            return String.Empty;
 
      return s.Remove(removeStartIndex);
}

use SubString:

gradeName = cellGradeValue.Value2.ToString().Substring(0, 80);

Are the single quotes part of the string?...

Rahul Goel

This will work for you

cellGradeValue.Value2.ToString().Substring(0,80).Trim()

I'm having another after misunderstanding the question the first time. This should trim all spaces at the end of a string.

String s = "NO.2 CANADA WESTERN AMBER DURUM (15.1)                                                   ";
s.TrimEnd(new char[] { ' ' });
