在GridView c#中按名称而不是按号码呼叫单元

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="PhoneNumber" OnSelectedIndexChanged="GridView1_SelectedIndexChanged">
    <Columns>
        <asp:BoundField DataField="PhoneNumber" HeaderText="号码" />
        <asp:TemplateField HeaderText="名称">
            <ItemTemplate>
                <asp:Label ID="lblName" runat="server" Text='<%# Eval("Name") %>'></asp:Label>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
    GridViewRow selectedRow = GridView1.SelectedRow;
    string phoneNumber = GridView1.DataKeys[selectedRow.RowIndex].Value.ToString();
    
    // 根据号码执行呼叫单元的操作
    // ...
}
