推荐答案

string strFile = "test.xml";

  try
  {
  doc = new XmlDocument();
  doc.Load(strFile);
  }
  catch (Exception ex)
  {
  MessageBox.Show(ex.Message);
  }

如果将xml文件路径写为"test.xml"，则必须将xml文件放在程序的exe文件目录中.

If you write xml file path as "test.xml" then you have to put the xml file in the directory of the program''s exe file.

这是什么意思，它确实无法加载xml?

What do you mean, it does not load the xml?

string strFile = "test1.xml";

xml是否在应用程序所在的根目录中?是目录搜索路径吗?您需要给它路径吗?

另外，您是否遇到异常，您在消息框中得到了什么?

Is the xml in your root directory where your app is located? Is it the directory search path? DO you need to give it the path?

Also, do you get an exception, what did you get in your message box?
