如何调用WCF服务中定义的进度条-C＃

Question

I have a client(WinForms Application)/Server (WCF Service) where I am doing some complex logic which writes packets to a remote host - this process takes about 20 minutes to write to a specific point but does not complete. So I want to show progress and attempt to continue from where I last stopped in my client application in the form of a progress bar.

  //Service:
  public class ServiceImplementation: IServiceInterface{
    ProgressBar pgBar = new ProgressBar();

  public void complexFunction(byte[] data_to_send, UInt32 start_addr){
     pgBar.Maximum = data_to_send.Length;
     for(int i = 0; i < data_to_send.Length; i += 64){
      //do some logic
     }
      pgBar.Value = i;
   }
 }

 //Client
  private void btnProgComplexFunction_Click(object sender, EventArgs e){
     callComplexFunction
  }

  void callComplexFunction(){
     ServiceImplementation.ServiceImplementationClient proxyInstance = new 
    ServiceImplementation.ServiceImplementationClient();

    //I attempted doing the following but obviously it doesn't work because progress bar returns an integer (e.g pgBar.Value = 100;). The problem lies here. I have been cracking my skull for two days straight
    pgBar.Value = proxyInstance.complexFunction(data_to_send, start_addr);}

You need to async call to your web service. Also need to soap client to this. You can achive it with download progress feature to do this.
