GridView绑定数据源List列排序
GridView，GirdList绑定数据源是泛型集合List<T>，对GridView进行列排序，使用List<T>自带的委托排序，实现方法如下（适用于C#2.0及以上语法）：
ASPX页面的HTML源码：
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="gvList" runat="server" AutoGenerateColumns="False" CellPadding="4"
ForeColor="#333333" GridLines="None" AllowSorting="true" OnSorting="gvList_Sorting">
<RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
<Columns>
<asp:BoundField DataField="ID" HeaderText="序号" SortExpression="ID" />
<asp:BoundField DataField="Name" HeaderText="姓名" SortExpression="Name" />
<asp:BoundField DataField="Height" HeaderText="身高" SortExpression="Height" />
<asp:BoundField DataField="Weight" HeaderText="体重" SortExpression="Weight" />
<asp:BoundField DataField="Salary" HeaderText="薪水" SortExpression="Salary" />
</Columns>
<FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
<HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<EditRowStyle BackColor="#999999" />
<AlternatingRowStyle BackColor="White" ForeColor="#284775" />
</asp:GridView>
</div>
</form>
</body>
对应的C#代码：
