C#学习教程：将generic.list转换为ArrayOfInt，以便通过SOAP传输到Web服务分享

我正在尝试使用SOAP协议将一个通用的整数列表从客户端应用程序传递给Web服务。

当我尝试将列表作为参数传递给Web服务中声明的Web方法时，我收到错误“无法从generic.list转换为ArrayOfInt”。

我该如何解决这个问题？

// web service method [WebMethod(CacheDuration = 30, Description = "Returns the calculated sum value of all numbers supplied in the list")] public int CalculateListSum(int[] list) { int _sum = 0; foreach (int _val in list) { _sum += _val; } return _sum; } // client app buton click event private void btnRun_Click(object sender, EventArgs e) { string str = this.tbValues.Text; // clear the list ClearIntList(); // take the textbox input, format and add to the List PopulateIntList(str); WSCalculate.CalculateSoapClient client = new WSCalculate.CalculateSoapClient(); int[] _int_array = this._int_list.ToArray(); // the line below is generating the error int _result = client.CalculateListSum(_int_array); this.tbResult.Text = _result.ToString(); } 

错误1&＃8217;WFCalculate.WSCalculate.CalculateSoapClient.CalculateListSum（WFCalculate.WSCalculate.ArrayOfInt）&＃8217;的最佳重载方法匹配具有一些无效参数WFCalculate Form1.cs 58 27 WFCalculate

错误2参数&＃8217;1&＃8217;：无法从&＃8217;int []&＃8217;转换为&＃8217;WFCalculate.WSCalculate.ArrayOfInt&＃8217;WFCalculate Form1.cs 58 51 WFCalculate

 int[] intArr = myList.ToArray(); 

 WFCalculate.WSCalculate.ArrayOfInt myClientArray = (WFCalculate.WSCalculate.ArrayOfInt)myList.ToArray(); int _result = client.CalculateListSum(myClientArray);
