SecureStringMarshal.SecureStringToCoTaskMemAnsi(SecureString) Method

Definition

Copies the contents of a managed SecureString object to a block of memory allocated from the unmanaged COM task allocator.

C#
public static IntPtr SecureStringToCoTaskMemAnsi(System.Security.SecureString s);

Parameters

s
SecureString

The managed object to copy.

Returns

IntPtr

The address, in unmanaged memory, where the s parameter was copied to, or 0 if a null object was supplied.

Exceptions

The s parameter is null.

There is insufficient memory available.

Remarks

The SecureStringToCoTaskMemAnsi method is useful for custom marshaling or when mixing managed and unmanaged code. Because this method allocates the unmanaged memory required for a string, always free the memory by calling ZeroFreeCoTaskMemAnsi. The characters of the string are copied as ANSI characters.
