Generated Proxy Classes Web Service Methods

Invoke the corresponding Web service methods. These methods exist at run time after the proxy class has been generated by the server.

Note

The names of the generated proxy class methods are based on the methods in the related Web service methods.

// Call a Web service method using the proxy class.
MyNameSpace.MyServiceProxy.MyServiceMethod(param1, param2, SucceededCallback, FailedCallback, userContext);

// Call a Web service method using a proxy class instance.
var myServiceProxy = MyNameSpace.MyService();
myServiceProxy.MyServiceMethod(param1, param2, SucceededCallback, FailedCallback, userContext);  

Parameters

Parameter	Definition
param1, param2, paramn	Parameters for the Web service method. You can pass as many parameters as are defined in the Web service method.
SucceededCallback	The succeeded callback function. This is an optional parameter. If you pass no value, the defaultSucceededCallback value is used, if defined; otherwise the call succeeds silently and no client processing of the results occurs. If you pass values to subsequent parameters in the method call, you must set SucceededCallback to null.
FailedCallback	The failed callback function. This is an optional parameter. If you pass no value, the defaultFailedCallback value is used, if defined; otherwise the Web service call fails silently. If you pass values to subsequent parameters in the method call, you must set FailedCallback to null.
userContext	An object that contains the user context. This is an optional parameter. If you pass no value, the defaultUserContext value is used, if defined; otherwise null is passed to the callback function.

Remarks

You can call Web service methods by using the generated proxy class. Alternatively, you can create an instance of the Web service proxy class. You can then specify the succeeded callback function, failed callback function, and, optionally, time-out or user context as properties of the instance. You can then use this proxy instance to call Web service methods. In that case, you do not have to pass the callback functions or user context in the call. If you do pass these values, they override any default values set as properties of the instance.

You can create multiple proxy class instances, each with different properties. You typically create instances of the generated proxy class when you want to apply different defaults, such as different callback functions, to different Web service calls. By using different callback functions, you can process the returned data in different ways, depending on your application needs. Calling methods of the proxy instance also simplifies the syntax of calling Web service methods and the logic of callback functions.

Example

The following example shows how to define the default values for a proxy class instance and then use the instance to call a Web service method.

    proxyInstance = 
        new  Samples.AspNet.UsingProxyClass();

    proxyInstance.set_timeout(1000);
    proxyInstance.set_defaultUserContext("New context");
    proxyInstance.set_defaultSucceededCallback(SucceededCallback);
    proxyInstance.set_defaultFailedCallback(FailedCallback);

    // Set the default color object.
    proxyInstance.SetColor(color);
