String.Remove Method (Int32, Int32)

Deletes a specified number of characters from this instance beginning at a specified position.

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

[SecuritySafeCriticalAttribute]
public string Remove(
	int startIndex,
	int count
)

Parameters

startIndex
Type: System.Int32
The zero-based position to begin deleting characters.
count
Type: System.Int32
The number of characters to delete.

Return Value

Type: System.String
A new string that is equivalent to this instance less count number of characters.

ExceptionCondition
ArgumentOutOfRangeException

Either startIndex or count is less than zero.

-or-

startIndex plus count specify a position outside this instance.

In the .NET Framework, strings are zero-based. The value of the startIndex parameter can range from zero to one less than the length of the string instance.

NoteNote:

This method does not modify the value of the current instance. Instead, it returns a new string in which the number of characters specified by the count parameter have been removed. The characters are removed at the position specified by startIndex.

The following code example demonstrates how you can remove the middle name from a complete name.


using System;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {

      string name = "Michelle Violet Banks";

      outputBlock.Text += String.Format("The entire name is '{0}'", name) + "\n";

      // remove the middle name, identified by finding the spaces in the middle of the name...
      int foundS1 = name.IndexOf(" ");
      int foundS2 = name.IndexOf(" ", foundS1 + 1);

      if (foundS1 != foundS2 && foundS1 >= 0)
      {

         name = name.Remove(foundS1 + 1, foundS2 - foundS1);

         outputBlock.Text += String.Format("After removing the middle name, we are left with '{0}'", name) + "\n";
      }
   }
}
