GridView 将 int类型 绑定（转成）为 string 类型

cs:

public string FormatState(string state)
        {
            if (state == "2")
            {
                return "1";
            }
            else
            {
                return "2";
            }
        }

aspx:

 <asp:Label ID="Label1" runat="server" Text='<%# FormatState(Eval("state").ToString()) %>'></asp:Label>
