String.TrimEnd Method

Removes all trailing occurrences of a set of characters specified in an array from the current string.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public string TrimEnd(
	params char[] trimChars
)

Parameters

trimChars
Type: System.Char[]
An array of Unicode characters to remove or null.

Return Value

Type: System.String
The string that remains after all occurrences of the characters in the trimChars parameter are removed from the end of the current string. If trimChars is null or an empty array, white-space characters are removed instead.

The TrimEnd method removes from the current string all trailing characters that are in the trimChars parameter. The trim operation stops when a character that is not in trimChars is encountered. For example, if the current string is "123abc456xyz789" and trimChars contains the digits from '1' through '9', the TrimEnd method returns "123abc456xyz".

NoteNote:

This method does not modify the value of the current instance. Instead, it returns a new string in which all trailing characters found in trimChars are removed from the current string.

For more information about which Unicode characters are categorized as white-space characters, see the Remarks section of the String.Trim() method overload.

The following code example demonstrates how you can use the TrimEnd(Char[]) method overload to trim white space or punctuation marks from the end of a string.


using System;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      string sentence = "The dog had a bone, a ball, and other toys.";
      char[] charsToTrim = {',', '.', ' '};
      string[] words = sentence.Split();
      foreach (string word in words)
         outputBlock.Text += word.TrimEnd(charsToTrim) + "\n";
   }
}
// The example displays the following output:
//       The
//       dog
//       had
//       a
//       bone
//       a
//       ball
//       and
//       other
//       toys
