将列表数据绑定到GridView。 GridView找不到我的财产！

Question

Given:

I have a class:

class MyObject
{
  public string Field1;
  public string Field2;
}

and the following code:

var list = SomeFunction(); // returns a valid List<MyObject>
gvMyList.DataSource = list;
gvMyList.DataBind(); // THIS THROWS AN EXCEPTION

And a GridView control in an aspx page:

<asp:GridView ID="gvMyList" AutoGenerateColumns="false" runat="server">
  <Columns>
    <asp:TemplateField HeaderText="Field 1">
      <ItemTemplate>
        <asp:Label ID="lblCourse" runat="server" Text='<%# Eval("Field1") + " " + Eval("Field2") %>'></asp:Label>
      </ItemTemplate>
    </asp:TemplateField>
  </Columns>
</asp:GridView>

Problem:

So I know that if something implements IEnumerable then it can be passed to the DataSource property. As far as I know, if you pass DataSource a List then I should have access to the MyObject 's properties by using Eval("Field1") or Eval("Field2") . Thats not the case here. Instead I get an exception thrown:

DataBinding: 'MyObject' does not contain a property with the name 'Field1'.

Answer 1

Your class contains Fields , not Properties ; You have to define Properties this way :

 class MyObject
    {
      public string Field1 { get; set; }
      public string Field2 { get; set; }
    }
