我试图将NAME提取到VB.NET的组合框中。尝试了几个例子，但没有奏效。请帮助，谢谢。





我有谷歌并尝试过互联网上的几个例子，但没有任何效果。任何heolp都会非常高兴。



我尝试过：

I am trying to fetch the "NAME" into a combo box in VB.NET. Tried several examples, but not working. Kindly help, thank you.


I have google and tried several examples from the internet, but nothing has worked. any heolp would be greatly apprecaited.

What I have tried:

<pre>Dim RA_File As String = "C:\Risk.xml"
        cbxList.Items.Clear()
        Dim xmlDoc As New XmlDocument()
        xmlDoc.Load(RA_File)
        Dim nodes As XmlNodeList = xmlDoc.DocumentElement.SelectNodes("/RISK/RISKITEM")
        Try
            For Each node As XmlNode In nodes
                cbxList.Items.Add(node.SelectSingleNode("NAME").InnerText)
            Next
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try

推荐答案

应该是：

Should be:

For Each node As XmlNode In nodes
      Dim name = node["NAME"].InnerText
      cbxList.Items.Add(Name)
Next
