SecureString.InsertAt Method

Inserts a character in this secure string at the specified index position.

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

[<HandleProcessCorruptedStateExceptionsAttribute>]
member InsertAt : 
        index:int * 
        c:char -> unit

Parameters

index
Type: System.Int32

The index position where parameter c is inserted.

c
Type: System.Char

The character to insert.

ExceptionCondition
ObjectDisposedException

This secure string has already been disposed.

InvalidOperationException

This secure string is read-only.

ArgumentOutOfRangeException

index is less than zero, or greater than the length of this secure string.

-or-

Performing this operation would make the length of this secure string greater than 65536 characters.

CryptographicException

An error occurred while encrypting or decrypting the value of this secure string.

The index is zero-based and the first character in this secure string is at index position zero.

The value of the secure string, if any, is decrypted; c is inserted at the specified location; then the new value is encrypted. The InsertAt method yields the same results as the AppendChar method, which inserts a character at the end of a secure string, if the index parameter of InsertAt is set to the length of this instance.

The following code example demonstrates how the AppendChar, InsertAt, RemoveAt, SetAt, and Clear methods affect the value of a SecureString object.

No code example is currently available or this language may not be supported.
