如何調用WCF服務中定義的進度條-C＃

Question

我有一個客戶端（WinForms應用程序）/服務器（WCF服務），在其中執行一些復雜的邏輯，該邏輯將數據包寫入遠程主機-此過程大約需要20分鍾才能寫入到特定點，但未完成。 因此，我想以進度條的形式顯示進度，並嘗試從上次停止在客戶端應用程序中繼續執行。

  //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);}

您需要異步調用Web服務。 還需要給客戶肥皂。 您可以使用下載進度功能來實現。
