我必须加载一个包含以下内容的xml文件我添加了root nood视图，因为我不知道xml文件不能有两个父对象，但无论我使用以下方法做什么，我都无法选择使该函数工作的路径。这是使用C#net 4

string text=System.IO.File.ReadAllText（@“XMLFile.XML”）；
XmlDocument currentDocument=新的XmlDocument（）；
尝试
{
currentDocument.LoadXml（文本）；
}

您忘记了路径中的第一个斜杠：

string path = "/View/Data";

第一条斜线表示绝对路径。如果省略它，则表示“基于当前匹配的节点选择
查看/数据
”，与
/View/Data
相同。但由于此时未选择任何节点，因此它不会返回任何内容
要返回所有数据节点，可以使用
/
子代选择器：

"//Data"
要选择除根元素以外的所有元素，请结合使用
*
：

"//*"

只需在路径中添加
/
，即可使其成为绝对路径
