Marshal.GetIDispatchForObjectInContext Method

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

Returns an IDispatch interface pointer from a managed object, if the caller is in the same context as that object.

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

public static IntPtr GetIDispatchForObjectInContext (
	Object o
)
public static IntPtr GetIDispatchForObjectInContext (
	Object o
)
public static function GetIDispatchForObjectInContext (
	o : Object
) : IntPtr

Parameters

o

The object whose IDispatch interface is requested.

Return Value

The IDispatch interface pointer for the o parameter, or a null reference (Nothing in Visual Basic) if the caller is not in the same context as the specified object.

Exception typeCondition

InvalidCastException

o does not support the requested interface.

ArgumentNullException

o is a null reference (Nothing in Visual Basic).

This method is the same as GetIDispatchForObject except that it returns a null reference (Nothing in Visual Basic) if the caller is not in the same context as the object.

NoteNote

This method uses 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.
