如何使用C＃将XML Web响应绑定到Windows窗体中的dataGridView中？

Question

我正在使用C＃中的Windows窗体中的插件进行工作。 我基本上是发送一个肥皂请求，并在xml中获得响应。 我现在只是在消息框中返回响应，但是我试图将响应绑定到datagrid视图中。 我怎样才能做到这一点？

这就是我的SOAP请求如下所示。

private void getEntitySummary(long entityID)
 {
      //Create client
      myAPI.ResolvingBinding resol = new myAPI.ResolvingBinding();

      //Create parameters
      myAPI.EntityID[] entityIDArr = new myAPI.EntityID[1];
      myAPI.EntityID entityIDitem = new myAPI.EntityID();
      entityIDitem.entityID = entityID;
      entityIDArr[0] = entityIDitem;
      myAPI.DepthSpecifier depth = new myAPI.DepthSpecifier();
      myAPI.CustomInformation customInfo = new myAPI.CustomInformation();

      //Make request
      myAPI.EntitySummary[] entitySummaryRes = resol.getEntitySummaries(entityIDArr, depth, customInfo);

      //Handle response            
      foreach (myAPI.EntitySummary e in entitySummaryRes)
      {
          string firstName = e.bestName?.givenName;
          string surName = e.bestName?.surname;
          string streetName = e.bestAddress?.street1;
          string city = e.bestAddress?.city;
          string state = e.bestAddress?.state;
          string country = e.bestAddress?.country;
          string address = (streetName + " " + city + " " + state + " " + country).Trim();
          string email = e.bestEmail?.emailAddress;
          string number = e.bestNumber?.numberValue;
          MessageBox.Show(firstName + " " + surName + ", " + address +", " + number );

          // need datagridView instead of a msg box here
      }
 }

该代码运行良好，并在后台以xml格式提供了响应。 它看起来像以下内容：

简而言之，我需要在dataGridView中绑定名称，地址和编号。 根据以上答复，将是：

我尝试了以下方法，但是我不明白如何将xml响应放入我的datagrid中：

 DataSet ds = new DataSet();
 XmlTextReader reader = new XmlTextReader(new StringReader(xml));
 ds.ReadXml(reader);
 dataGridView1.DataSource = ds;

任何帮助将不胜感激！

ReadXml无法使用，因为xml上的嵌套级别数太深。 最终，您将获得大量数据表，并且数据碎片化，无法将数据放回可用格式。 我将致力于解决方案。 请花我几分钟。
