Visual Studio 2010
Defines the method call message interface.
Assembly: mscorlib (in mscorlib.dll)
The IMethodCallMessage type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | ArgCount | Gets the number of arguments passed to the method. (Inherited from IMethodMessage.) |
![]() | Args | Gets an array of arguments passed to the method. (Inherited from IMethodMessage.) |
![]() | HasVarArgs | Gets a value indicating whether the message has variable arguments. (Inherited from IMethodMessage.) |
![]() | InArgCount | Gets the number of arguments in the call that are not marked as out parameters. |
![]() | InArgs | Gets an array of arguments that are not marked as out parameters. |
![]() | LogicalCallContext | Gets the LogicalCallContext for the current method call. (Inherited from IMethodMessage.) |
![]() | MethodBase | Gets the MethodBase of the called method. (Inherited from IMethodMessage.) |
![]() | MethodName | Gets the name of the invoked method. (Inherited from IMethodMessage.) |
![]() | MethodSignature | Gets an object containing the method signature. (Inherited from IMethodMessage.) |
![]() | Properties | Gets an IDictionary that represents a collection of the message's properties. (Inherited from IMessage.) |
![]() | TypeName | Gets the full Type name of the specific object that the call is destined for. (Inherited from IMethodMessage.) |
![]() | Uri | Gets the URI of the specific object that the call is destined for. (Inherited from IMethodMessage.) |
| Name | Description | |
|---|---|---|
![]() | GetArg | Gets a specific argument as an Object. (Inherited from IMethodMessage.) |
![]() | GetArgName | Gets the name of the argument passed to the method. (Inherited from IMethodMessage.) |
![]() | GetInArg | Returns the specified argument that is not marked as an out parameter. |
![]() | GetInArgName | Returns the name of the specified argument that is not marked as an out parameter. |
