Ends an asynchronous invocation of an XML Web service method using SOAP.
Assembly: System.Web.Services (in System.Web.Services.dll)
Return ValueType: System.Object
An array of objects that contains the return value and any by-reference or out parameters of the derived class method.
asyncResult is not the return value from the BeginInvoke method.
The request reached the server computer, but was not processed successfully.
The request was not valid for the object's current state.
An error occurred while accessing the network.
Typically, you would not call the method directly, unless you were building your own proxy class for an XML Web service.
A proxy class generated by the Web Services Description Language tool (Wsdl.exe) for an XML Web service exposes the XML Web service methods as names off of the proxy class for calling the XML Web service methods synchronously. For calling the XML Web service methods asynchronously, two additional methods are added to the proxy class for each XML Web service method, one with the Begin prefix added to the name of the XML Web service method and one with the End prefix added.
The proxy class calls the method to complete an asynchronous invocation call to the XML Web service method. For example, if an XML Web service exposes an XML Web service method named Add, the proxy class contains a method named EndAdd, for completing an asynchronous invocation of an XML Web service method. Within the code for the EndAdd a call is made to the method and then the results are placed into the expected return type for Add.
The following code example is a proxy class generated by Wsdl.exe for the Math XML Web service. Within the EndAdd method of the proxy class, the method completes the asynchronous invocation to the Add XML Web service method.
The following code example is the Math XML Web service, from which the preceding proxy class was created.
