我的网络服务返回XML字符串Response。我有这些数据在Grid-view上显示它。怎么办？我的网络服务的请求和响应代码

string requestXml2 = requestXml.ToString();
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
        byte[] bytes;
        bytes = System.Text.Encoding.ASCII.GetBytes(requestXml2);
        request.ContentType = "text/xml; encoding='utf-8'";
        request.ContentLength = bytes.Length;
        request.Method = "POST";
        Stream requestStream = request.GetRequestStream();
        requestStream.Write(bytes, 0, bytes.Length);
        requestStream.Close();
        HttpWebResponse response;
        response = (HttpWebResponse)request.GetResponse();
        if (response.StatusCode == HttpStatusCode.OK)
        {
            Stream responseStream = response.GetResponseStream();
            string responseStr = new StreamReader(responseStream).ReadToEnd();
            return responseStr ;
        }

此代码返回此XML字符串

这是我如何绑定网格

WebService service = new WebService();
 string xml = service.FindCountry();\\ getting xml string 
        DataSet ds = new DataSet();
        XmlTextReader reader = new XmlTextReader(new StringReader(xml));
           GridView1.DataSource = (ds.ReadXml(reader));
            GridView1.DataBind();

异常绑定gridview时获取

数据源是无效类型。它必须是IListSource， IEnumerable，或IDataSource。

Answer 1

ReadXml()会返回XmlReadMode，您无法将其分配为DataSource，这就是您获得例外的原因。相反，您希望填充DataSet并将其分配为DataSource在单独的行中：

DataSet ds = new DataSet();
XmlTextReader reader = new XmlTextReader(new StringReader(xml));
ds.ReadXml(reader);
GridView1.DataSource = ds;
GridView1.DataBind();

将Webservice响应绑定到GridView中
