ClientBase<TChannel> Constructor

Initializes a new instance of the ClientBase<TChannel> class using the default target endpoint from the application configuration file.

Namespace:  System.ServiceModel
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

protected ClientBase()

ExceptionCondition
InvalidOperationException

Either there is no default endpoint information in the configuration file, more than one endpoint in the file, or no configuration file.

Use this constructor to create a client object to invoke a service. This constructor uses the type parameter as the target contract and the binding and address information from the application configuration file.

The following code example shows how a client uses this constructor in a SampleServiceClient class that extends the ClientBase<TChannel> class.


using System;
using System.ServiceModel;
using System.ServiceModel.Channels;

public class Client
{
  public static void Main()
  {
    // Picks up configuration from the config file.
    SampleServiceClient wcfClient = new SampleServiceClient();
    try
    {
        // Making calls.
        Console.WriteLine("Enter the greeting to send: ");
        string greeting = Console.ReadLine();
        Console.WriteLine("The service responded: " + wcfClient.SampleMethod(greeting));

        Console.WriteLine("Press ENTER to exit:");
        Console.ReadLine();

        // Done with service. 
        wcfClient.Close();
        Console.WriteLine("Done!");
    }
    catch (TimeoutException timeProblem)
    {
      Console.WriteLine("The service operation timed out. " + timeProblem.Message);
      wcfClient.Abort();
      Console.Read();
    }
    catch(CommunicationException commProblem)
    {
      Console.WriteLine("There was a communication problem. " + commProblem.Message);
      wcfClient.Abort();
      Console.Read();
    }
  }
}
