MethodBuilder.SetMarshal Method

Note: This API is now obsolete.

Sets marshaling information for the return type of this method.

Namespace:  System.Reflection.Emit
Assembly:  mscorlib (in mscorlib.dll)

[ObsoleteAttribute("An alternate API is available: Emit the MarshalAs custom attribute instead. http://go.microsoft.com/fwlink/?linkid=14202")]
public void SetMarshal(
	UnmanagedMarshal unmanagedMarshal
)

Parameters

unmanagedMarshal
Type: System.Reflection.Emit.UnmanagedMarshal

Marshaling information for the return type of this method.

ExceptionCondition
InvalidOperationException

The containing type was previously created using CreateType.

-or-

For the current method, the IsGenericMethod property is true, but the IsGenericMethodDefinition property is false.

The code sample below illustrates the contextual usage of the SetMarshal method to marshal the results of a method call as a different type.


	MethodBuilder myMethod = myDynamicType.DefineMethod("MyMethodReturnsMarshal",
						MethodAttributes.Public,
						typeof(uint),
						new Type[] { typeof(string) });

	// We want the return value of our dynamic method to be marshalled as  
	// an 64-bit (8-byte) signed integer, instead of the default 32-bit 
   	// unsigned int as specified above. The UnmanagedMarshal class can perform 
	// the type conversion.

	UnmanagedMarshal marshalMeAsI8 = UnmanagedMarshal.DefineUnmanagedMarshal(
				         System.Runtime.InteropServices.UnmanagedType.I8);	

	myMethod.SetMarshal(marshalMeAsI8);
