上下文找不到已经设定好的commandname解决办法_ASP.NET

上下文找不到已经设定好的commandname

HTML code

<asp:LinkButton ID="LinkButton1" runat="server" CommandName="Edit" OnEditCommand="DataList1_EditCommand">确认接收</asp:LinkButton></td>                                </tr>

C# code

protected void DataList1_EditCommand(object source, DataListCommandEventArgs e)    {        if (e.CommandName==Edit)        {            bc.ExecSQL("UPDATE [file] SET examine = '已接收' WHERE fileID ='" + (int)DataList1.DataKeys[e.Item.ItemIndex] + "'");            DataList1.DataSource = bc.GetDataSet("select * from [file] where fileAccepter='" + Session["loginName"].ToString() + "' order by fileTime desc", "file");            DataList1.DataKeyField = "fileid";            DataList1.DataBind();        }
