1.獲取系統版本號   Version version = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version; 2.格式化   string ver = string.Format("{0}.{1}.{2}.{3}", version.Major, version.Minor, version.Build, version.Revision.ToString("0000")); 2.不做另外處理,直接使用   string ver = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString() 參考網址:  By Hao★

下載指定目錄下的文件   protected void DownloadFile( string filename, string filepath) { Response.Clear(); Response.AddHeader( "Content-Disposition" , "attachment; filename=" + HttpUtility .UrlEncode(filename, System.Text.Encoding .Default)); Response.ContentType = "application/octet-stream" ; Response.TransmitFile(filepath); Response.End(); } 參考網址:  By Hao★

查詢包含特定副檔名或是檔案中含有某關鍵字   using System.Text.RegularExpressions; using System.IO; private void FindFile(string dir) { DirectoryInfo Dir = new DirectoryInfo(dir); try { string filepath = ""; foreach (FileInfo file in Dir.GetFiles("*.xls"))//查詢附檔名為xls的文件 { Regex regex = new Regex(@"friend");//查詢檔案名稱中有關鍵字friend的文件 Match match = regex.Match(file.ToString()); if (match.Success) { filepath = Dir + file.ToString()); } } } catch (Exception ex) { Console.WriteLine(ex.Message); } } 參考網址:  By Hao★

隐藏列   GridPanel_1.ColumnModel.SetHidden(1, true); 參考網址:  By Hao★

1.判斷GridPanel中是否選中了某列   if(!GridPanel1.hasSelection()) { Ext.Msg.alert("提示", "請選擇資料!"); return; } 2.獲取選中行的數據   var record = GridPanel1.selModel.getSelected(); var ID = record.data.ID; ID為GridPanel1的Store的欄位名稱。 3.獲取GridPanel中所有的數據   var data = GridPanel1.getStore().getRange(); 可以將得到的所有數據轉換成Josn傳给後台： var Datas = []; var data = GridPanel1.getStore().getRange(); Ext.each(data, function(record) { Datas.push(record.data); }); var jsonData = Ext.encode(Datas); return jsonData; 參考網址:  Ext.Net 使用总结之GridPanel中的选中行   By Hao★

前台   <ext:CompositeField ID="CompositeField2" runat="server" FieldLabel="時間"> <Items> <ext:DateField ID="date_start" Vtype="daterange" runat="server" Flex="1"> <Listeners> <Render Handler="this.endDateField = '#{date_end}'" /> </Listeners> </ext:DateField> <ext:Label ID="Label2" runat="server" Text="~"> </ext:Label> <ext:DateField ID="date_end" Vtype="daterange" runat="server" Flex="1"> <Listeners> <Render Handler="this.startDateField = '#{date_start}'" /> </Listeners> </ext:DateField> </Items> </ext:CompositeField> 參考網址: Ext.Net 使用总结之查询条件中的起始日期   By Hao★
