StringBuilder.Remove Method

Removes the specified range of characters from this instance.

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

member Remove : 
        startIndex:int * 
        length:int -> StringBuilder 


Type: System.Int32
The zero-based position in this instance where removal begins.
Type: System.Int32
The number of characters to remove.

Return Value

Type: System.Text.StringBuilder
A reference to this instance after the excise operation has completed.


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

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 the current instance is unaffected.


The Remove method modifies the value of the current StringBuilder instance and returns that instance. It does not create and return a new StringBuilder object.

The following example demonstrates the Remove method.
