我有一个xml文件

I have a xml file

<Student>
  <Students Name="StudentName" Type="string" symbol="=,%,!=" /> 
  <Students Name="EmployeeName" Type="string" symbol="=,%,!=" /> 
  <Students Name="ManagerName" Type="undefines" symbol="=,%,!=" /> 
  <undefined value="1" Name="Manager1">
  <undefined value="2" Name="Manager2">
  <Students Name="Level1" Type="string" Operators="=,%,!=" /> 
  <Students Name="Level2" Type="undefines" Operators="=,%,!=" />

推荐答案

在您的aspx页面上添加两个下拉列表。

在页面加载下调用以下函数：

Add two dropdown lists to your aspx page.
Call below function on page load:

public void LoadXML()
       {
           string myXMLfile = Server.MapPath("~/YourFile.xml");
           DataSet ds = new DataSet();
           try
           {
               dsStudent.ReadXml(myXMLfile);
               DropDownList1.DataSource = ds;
               DropDownList1.DataValueField = "Name";
               DropDownList1.DataTextField = "Name";
               DropDownList1.DataBind();

               DropDownList2.DataSource = ds;
               DropDownList2.DataValueField = "Name";
               DropDownList2.DataTextField = "symbol";
               DropDownList2.DataBind();


           }
           catch (Exception ex)
           {
               Response.Write(ex.ToString());
           }
       }

将SlectedIndex更改事件添加到DropDownList1：

Add SlectedIndex change event to DropDownList1:

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{

  DropDownList2.Items.FindByValue(DropDownList1.SelectedValue).Selected = true;

}
