String.Remove Method (Int32)

 

Returns a new string in which all the characters in the current instance, beginning at a specified position and continuing through the last position, have been deleted.

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

public string Remove(
	int startIndex
)

Parameters

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 except for the removed characters.

Exception Condition
ArgumentOutOfRangeException

startIndex is less than zero.

-or-

startIndex specifies a position that is not within this string.

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.

System_CAPS_noteNote

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 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 Sample 
{
    public static void Main() 
    {
    string s = "abc---def"; 
//
    Console.WriteLine("Index: 012345678");
    Console.WriteLine("1)     {0}", s);
    Console.WriteLine("2)     {0}", s.Remove(3)); 
    Console.WriteLine("3)     {0}", s.Remove(3, 3));
    }
}
/*
This example produces the following results:

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