System.Runtime.Remoting.Messaging.IMethodMessage Interface

Summary

Defines the method message interface.

C# Syntax:

public interface IMethodMessage : IMessage

A method message is used to send information to and from remote methods. For example, messages used for remote method calls implement the IMethodMessage interface.

System.Runtime.Remoting.Messaging.IMethodMessage Member Details

Summary

Gets the number of arguments passed to the method.

C# Syntax:

int ArgCount {get;}

Return to top

Summary

Gets an array of arguments passed to the method.

C# Syntax:

object[] Args {get;}

Although the IMethodMessage.Args property is redundant since the same functionality can be achieved through the IMethodMessage.ArgCount and IMethodMessage.GetArg, there might be performance optimization available if the implementer understands when all the arguments will be retrieved.

Return to top

Summary

Gets a value indicating whether the message has variable arguments.

C# Syntax:

bool HasVarArgs {get;}

Return to top

Summary

Gets the LogicalCallContext for the current method call.

C# Syntax:

LogicalCallContext LogicalCallContext {get;}

Return to top

Summary

Gets the MethodBase of the called method.

C# Syntax:

MethodBase MethodBase {get;}

This information is not transmitted to a remote location, but is used to cache the method base after it has been looked up once.

Return to top

Summary

Gets the name of the invoked method.

C# Syntax:

string MethodName {get;}

Return to top

Summary

Gets an object containing the method signature.

C# Syntax:

object MethodSignature {get;}

All the current implementations of IMethodMessage return an array of Type objects containing the parameter types of the method.

Return to top

Summary

Gets the full Type name of the specific object that the call is destined for.

C# Syntax:

string TypeName {get;}

Return to top

Summary

Gets the URI of the specific object that the call is destined for.

C# Syntax:

string Uri {get;}

Return to top

Summary

Gets a specific argument as an Object.

C# Syntax:

object GetArg(    int argNum );

argNum

The number of the requested argument.

Return Value:

The argument passed to the method.

Return to top

Summary

Gets the name of the argument passed to the method.

C# Syntax:

string GetArgName(    int index );

index

The number of the requested argument.

Return Value:

The name of the specified argument passed to the method, or null if the current method is not implemented.
