String.Remove Method (Int32)

July 28, 2014

Deletes all the characters from this string beginning at a specified position and continuing through the last position.

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

public string Remove(
	int startIndex


Type: System.Int32
The zero-based position to begin deleting characters.

Return Value

Type: System.String
A new string that is equivalent to this string without the removed characters.


startIndex is less than zero.


startIndex specifies a position that is not within this string.

Strings are zero-based. The value of the startIndex parameter can range from zero to one less than the length of the string instance.


This method does not modify the value of the current instance. Instead, it returns a new string in which all characters from position startIndex to the end of the original string have been removed.

The following code example demonstrates the Remove method. The next-to-last case removes all text starting from the specified index through the end of the string. The last case removes three characters starting from the specified index.

// This example demonstrates the String.Remove() method.
using System;

class Example
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
      string s = "abc---def";
      outputBlock.Text += "Index: 012345678" + "\n";
      outputBlock.Text += String.Format("1)     {0}", s) + "\n";
      outputBlock.Text += String.Format("2)     {0}", s.Remove(3)) + "\n";
      outputBlock.Text += String.Format("3)     {0}", s.Remove(3, 3)) + "\n";
This example produces the following results:

Index: 012345678
1)     abc---def
2)     abc
3)     abcdef
