推荐答案

写一个类似于此&的LINQ.试试

Write a LINQ similar to this & try

// Create the query
            var books = from c in System.Xml.Linq.XElement.Load("Books.xml").Elements("Text")
                        select c;
            if (books != null)
            {
                foreach (var b in books)
                {

                    string subjectvalue = b.Element("Subject").Value; //will give you Alpha
                }
            }

所以您要面对什么问题，您需要解析XML并访问适当的节点，并将其分配给Label的text属性.

您可以使用XPath查询XML.例如，查看链接

So what problem you are facing, You need to parse the XML and access the appropriate nodes and assign it to Label''s text property.

You can query to your XML using XPath. Have a look to the link for example

您可以使用类似

You may use something like

XmlDocument xmldoc = new XmlDocument();
xmldoc.Load("mydata.xml");
label1.Text = xmldoc.SelectSingleNode("/Books/Text/Subject").FirstChild.Value;
label2.Text = xmldoc.SelectSingleNode("/Books/Text/Content").FirstChild.Value;

只要您正确修复了XML文档(底部节点应为</Books>)

Provided you correctly fix your XML document (the bottom node should be </Books>)
