Marshal.Prelink Method

Executes one-time method setup tasks without calling the method.

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

public static void Prelink (
	MethodInfo m
)
public static void Prelink (
	MethodInfo m
)
public static function Prelink (
	m : MethodInfo
)

Parameters

m

A System.Reflection.MethodInfo that identifies the method to be checked.

Exception typeCondition

ArgumentNullException

The m parameter is a null reference (Nothing in Visual Basic).

ArgumentException

The m parameter is not a MethodInfo object.

Setup tasks provide early initialization and are performed automatically when the target method is invoked. First-time tasks include:

  • Verifying that the platform invoke metadata is correctly formatted.

  • Verifying that all the managed types are valid parameters of platform invoke functions.

  • Locating and loading the unmanaged DLL into the process.

  • Locating the entry point in the process.

Calling Prelink on a method outside of platform invoke has no effect. To execute setup tasks on all platform invoke methods in a type, use Marshal.PrelinkAll.

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.
