Namespace:  System.Runtime.Remoting.Messaging
Assembly:  mscorlib (in mscorlib.dll)

int OutArgCount { get; }

Property Value

Type: System.Int32
The number of arguments in the method call marked as ref or out parameters.


The immediate caller makes the call through a reference to the interface and does not have infrastructure permission.

The following example code shows a custom proxy that overrides RealProxy.Invoke in order to write the return message information to the console.

public override IMessage Invoke(IMessage myMessage)
   IMethodCallMessage myCallMessage = (IMethodCallMessage)myMessage;

   IMethodReturnMessage myIMethodReturnMessage =
      RemotingServices.ExecuteMessage(myMarshalByRefObject, myCallMessage);

   Console.WriteLine("Method name : " + myIMethodReturnMessage.MethodName);
   Console.WriteLine("The return value is : " + myIMethodReturnMessage.ReturnValue);

   // Get number of 'ref' and 'out' parameters.
   int myArgOutCount = myIMethodReturnMessage.OutArgCount;
   Console.WriteLine("The number of 'ref', 'out' parameters are : " +
   // Gets name and values of 'ref' and 'out' parameters.
   for(int i = 0; i < myArgOutCount; i++)
      Console.WriteLine("Name of argument {0} is '{1}'.",
         i, myIMethodReturnMessage.GetOutArgName(i));
      Console.WriteLine("Value of argument {0} is '{1}'.",
         i, myIMethodReturnMessage.GetOutArg(i));
   object[] myObjectArray = myIMethodReturnMessage.OutArgs; 
   for(int i = 0; i < myObjectArray.Length; i++)
      Console.WriteLine("Value of argument {0} is '{1}' in OutArgs",
         i, myObjectArray[i]);
   return myIMethodReturnMessage;
