Marshal.ZeroFreeCoTaskMemUnicode Method

Note: This method is new in the .NET Framework version 2.0.

Frees an unmanaged string pointer that was allocated using the SecureStringToCoTaskMemUnicode method.

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

public static void ZeroFreeCoTaskMemUnicode (
	IntPtr s
)
public static void ZeroFreeCoTaskMemUnicode (
	IntPtr s
)
public static function ZeroFreeCoTaskMemUnicode (
	s : IntPtr
)

Parameters

s

The address of the unmanaged string to free.

The ZeroFreeCoTaskMemUnicode method first zeros out and then frees unmanaged memory that was allocated using the SecureStringToCoTaskMemUnicode method.

NoteNote

This method uses SecurityAction.LinkDemand to prevent it from being called from untrusted code; only the immediate caller is required to have SecurityPermissionAttribute.UnmanagedCode permission. If your code can be called from partially trusted code, do not pass user input to Marshal class methods without validation. For important limitations on using the LinkDemand member, see Demand vs. LinkDemand.
