誤差はここ

Question

は私の二つの機能です：

public void SetCompanies() 
    //set the Companies table from Shret.net DataBase 
    { 
     try 
     { 
      WebClient webClient = new WebClient(); 
      Uri uri = new Uri("http://api.sherut.net/?method=Company"); 
      webClient.OpenReadCompleted += new OpenReadCompletedEventHandler(webClient_OpenReadCompleted); 

      try 
      { 
       webClient.OpenReadAsync(uri); 
      } 
      catch (Exception ex) 
      { 
       MessageBox.Show(ex.Message); 
      } 
     } 
     catch (Exception ex) 
     { 
      MessageBox.Show(ex.Message); 
     } 
    } 
    void webClient_OpenReadCompleted(object sender, OpenWriteCompletedEventArgs e) 
    { 
     try 
     { 
      DataContractJsonSerializer serializer = null; 
      var companies = (Companies)serializer.ReadObject(e.Result); 
      foreach (Company c in companies.data) 
      { 
       MessageBox.Show(c.Name + " " + c.CompanyID); 
      } 
     } 
     catch (Exception ex) 
     { 
      MessageBox.Show(ex.Message); 
     } 
    } 
} 

、これは私が取得エラーです：

'webClient_OpenReadCompleted' の「いいえ過負荷が 「System.Net.OpenReadCompletedEventHandlerを委任一致しません'"

なぜこの機能の後にハンドラを書いたのかわかりません...... dvance！

Answer 1

OpenReadCompletedOpenWriteCompletedEventArgsを使用していません。
