Question

在尝试将XML绑定到Combobox数据源时，我收到错误“ 复杂数据绑定接受IList或IListSource作为数据源。 ”

 XDocument obj = XDocument.Load("Managers.xml");

 comboBox1.DisplayMember = "ManagerDesig";
 comboBox1.ValueMember = "ManagerID";
 comboBox1.DataSource = obj.Descendants("manager").Select(x => new
 {
   ManagerDesig = x.Attribute("desig").Value,
   ManagerID = x.Attribute("id").Value
 });

Managers.xml

<managers>
  <manager id="123" desig="CEO" />
  <manager id="234" desig="CFO" />
  <manager id="456" desig="CIO" />
</managers>

请帮忙

Answer 1

尝试：

 comboBox1.DataSource = obj.Descendants("manager").Select(x => new
 {
   ManagerDesig = x.Attribute("name").Value,
   ManagerID = x.Attribute("id").Value
 })
.ToList();//convert to list

Answer 2

首先，您的示例中存在拼写错误：您正在检索“name”属性，而只定义了“id”和“desig”属性。

其次，使用ToList扩展方法，如下所示：

comboBox1.DataSource = obj.Descendants("manager").Select(x => new
{
    ManagerDesig = x.Attribute("name").Value,
    ManagerID = x.Attribute("id").Value
}).ToList();
