StringBuilder.Remove Method

.NET Framework 2.0

Other Versions

Removes the specified range of characters from this instance.

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

Syntax

C++

Copy

public StringBuilder Remove (
	int startIndex,
	int length
)

Copy

public StringBuilder Remove (
	int startIndex, 
	int length
)

JScript

Copy

public function Remove (
	startIndex : int, 
	length : int
) : StringBuilder

Parameters

startIndex: The position in this instance where removal begins.

length: The number of characters to remove.

Return Value

A reference to this instance after the excise operation has completed.

Exceptions

Exception type	Condition
ArgumentOutOfRangeException	If startIndex or length is less than zero, or startIndex + length is greater than the length of this instance.

Remarks

The current method removes the specified range of characters from the current instance. The characters at (startIndex + length) are moved to startIndex, and the string value of the current instance is shortened by length. The capacity of current instance is unaffected.

Example

The following code example demonstrates the Remove method.

C++

Copy

using System;
using System.Text;

class Sample 
{
    public static void Main() 
    {
    string rule1 = "0----+----1----+----2----+----3----+----4---";
    string rule2 = "01234567890123456789012345678901234567890123";
    string str =   "The quick brown fox jumps over the lazy dog.";
    StringBuilder sb = new StringBuilder(str);

    Console.WriteLine();
    Console.WriteLine("StringBuilder.Remove method");
    Console.WriteLine();
    Console.WriteLine("Original value:");
    Console.WriteLine(rule1);
    Console.WriteLine(rule2);
    Console.WriteLine("{0}", sb.ToString());
    Console.WriteLine();

    sb.Remove(10, 6); // Remove "brown "

    Console.WriteLine("New value:");
    Console.WriteLine(rule1);
    Console.WriteLine(rule2);
    Console.WriteLine("{0}", sb.ToString());
    }
}
