我打開窗體時使用C#中的RestSharp調用Restful API,但在調用此GUI時會打開並鎖定。RestSharp異步API - 更新GUI

只是想知道我在做什麼錯?

我已經調用而BeginInvoke之間變化,但沒有運氣 - 調試輸出,似乎第一&第二調用之間的某處掛電話

public void show_members(String url, String api_key, String card_number) 
{ 
    member_numbers.Clear(); 
    st_url = url; 
    st_api_key = api_key; 
    st_card_number = card_number; 

    var client = new RestClient(url); 

    var request = new RestRequest("pendingmembers?api_key={api_key}", Method.GET); 
    request.AddUrlSegment("api_key", api_key); 

    Debug.WriteLine(url + "pendingmembers?api_key=" + api_key); 

    // async with deserialization 
    var asyncHandle = client.ExecuteAsync<PendingMembers>(request, response => 
    { 
     Debug.WriteLine(response.Data.status); 
     if (response.Data.status == "OK") 
     { 
      //Company ID is Correct 
      //Dispatcher.Invoke((Action)() => {cb_MemberList.Items.Clear();}); 
      if (this.InvokeRequired) 
      { 
       this.Invoke((Action)(() => 
       { 
        cb_MemberList.Items.Clear(); 
       })); 
      } 
      else 
      { 
       cb_MemberList.Items.Clear(); 
      } 
      //Debug.WriteLine(response.Data.members); 
      foreach(var member in response.Data.members) 
      { 
       Debug.WriteLine(member.full_name); 
       member_numbers.Add(member.member_id); 
       if (this.InvokeRequired) 
       { 
        this.Invoke((Action)(() => 
        { 
         Debug.WriteLine(member.full_name); 
         cb_MemberList.Items.Add(member.full_name); 
        })); 
       } 
       else 
       { 
        Debug.WriteLine(member.full_name); 
        cb_MemberList.Items.Add(member.full_name); 
       } 
      } 
      Application.DoEvents(); 
     } 
    }); 
}

解決了這個問題 - 完美地工作,因爲註釋掉整個Web API調用仍然導致UI掛起。

在檢查這是window.Show()而非window.ShowDialog()導致了問題...

這個故事的寓意,更多的睡眠!
