Operation.Messages Property

Gets the collection of instances of the Message class defined by the current Operation.

Namespace:  System.Web.Services.Description
Assembly:  System.Web.Services (in System.Web.Services.dll)

public OperationMessageCollection Messages { get; }

Because an Operation is associated with exactly one OperationInput and exactly one OperationOutput, only one instance of each can be a member of this collection, and thus the collection can have a maximum of two members.

// Create an Operation.
Operation myOperation = new Operation();
myOperation.Name = myOperationName;
OperationMessage myInput = (OperationMessage)new OperationInput();
myInput.Message =  new XmlQualifiedName(myInputMesg);
OperationMessage myOutput = (OperationMessage)new OperationOutput();
myOutput.Message = new XmlQualifiedName(myOutputMesg);

// Add messages to the OperationMessageCollection.
myOperation.Messages.Add(myInput);
myOperation.Messages.Add(myOutput);
Console.WriteLine("Operation name is: " + myOperation.Name);     
// Create an Operation.
Operation* myOperation = new Operation();
myOperation->Name = myOperationName;
OperationMessage* myInput = dynamic_cast<OperationMessage*>(new OperationInput());
myInput->Message =  new XmlQualifiedName(myInputMesg);
OperationMessage* myOutput = dynamic_cast<OperationMessage*>(new OperationOutput());
myOutput->Message = new XmlQualifiedName(myOutputMesg);

// Add messages to the OperationMessageCollection.
myOperation->Messages->Add(myInput);
myOperation->Messages->Add(myOutput);
Console::WriteLine(S"Operation name is: {0}", myOperation->Name);
