这是我的情况，我可以编写不带任何问题示例的xml

IM GOING CRAZY !!!

推荐答案

以下是读取XML文件的方法:

Here is how you could read an XML file:

Dim name as string

Public Sub Load(ByVal p_XMLfilename As String)
       XMLFilename = p_XMLfilename

       Dim x As New System.Xml.XmlDocument
       x.Load(p_XMLfilename)

       Dim x_nodes As System.Xml.XmlNodeList = x.SelectNodes("employee")
       For Each node As System.Xml.XmlNode In x_nodes

           For Each node2 As System.Xml.XmlNode In node
               Select Case node2.Name
                   Case Is = "FirstName" : name = node2.InnerText

               End Select
           Next

       Next
   End Sub

您尝试了什么?您知道如何使用 LINQ to XML [ ^ ]或 XmlDocument [ OpenFileDialog [

What have you tried ? Do you know how to use LINQ to XML[^] or the XmlDocument[^] class to read and parse XML ? Do you know how to use the OpenFileDialog[^] class ?
