本篇文章主要是對asp.net上傳execl文件後,在頁面上加載顯示(示例代碼)進行了介紹，需要的朋友可以過來參考下，希望對大家有所幫助
代碼如下: #region 上傳Execl文件 protected void Button1_Click(object sender, EventArgs e) { if (FileUpload1.HasFile) { string NewFileName = string.Empty; string ErrorMess = UpLoadFile(FileUpload1, ".xls|.xlsx", 1024 * 5, Server.MapPath("/Report/SocialApply/"), 1, out NewFileName); if (string.IsNullOrEmpty(ErrorMess)) { Label1.Text = "√文件上傳成功"; ViewState["UpLoadFile"] = "/Report/SocialApply/" + NewFileName; try { FileStream file = new FileStream (Server.MapPath(ViewState["UpLoadFile"] as string), FileMode.Open, FileAccess.Read, FileShare.ReadWrite); DataTable dt1 = FairHR.Util.XmlExcelReport.ReadExcelToDataTable(file, 0, 0); ViewState.Add("ViewDT", dt1); GridView1.DataSource = ViewState["ViewDT"] as DataTable; GridView1.DataBind(); file.Close(); //Maticsoft.Common.MessageBox.ResponseScript(Page, "$.messager.alert('系統提示', '操作成功！', 'info');"); } catch { Maticsoft.Common.MessageBox.ResponseScript(Page, "$.messager.alert('系統提示', '請重新上傳Execl文件再操作', 'warning');"); } } else { Label1.Text = "×文件上傳失敗"; } } else { Label1.Text = "×請先選擇上傳文件"; } ScriptManager.RegisterClientScriptBlock(Page, this.GetType(), "idAlert1", "closeLoad();", true); } #endregion #region 上傳文件 /// <summary> /// 上傳文件 /// </summary> /// <param name="fu">上傳文件</param> /// <param name="type">上傳文件類型,例如.jpg|.gif|.bmp</param> /// <param name="size">限制上傳文件大小，單位為k</param> /// <param name="path">上傳路徑，需使用server.mappath</param> /// <param name="nametype">1為自動命名,0用原名</param> /// <returns></returns> public static string UpLoadFile(FileUpload fu, string type, int size, string path, int nametype, out string newFileName) { newFileName = null; string erorr = null; int Size = fu.PostedFile.ContentLength / 1024; if (Size > size) { erorr = "上傳文件太大！"; return erorr; } string Type = fu.FileName; if (Type.IndexOf(".") == -1) { erorr = "上傳文件類型有誤！"; return erorr; } Type = Type.Substring(Type.LastIndexOf(".")).ToUpper(); type = type.ToUpper(); if (type.IndexOf(Type) == -1) { erorr = "上傳文件類型有誤！"; return erorr; } string filename = ""; if (nametype == 1) { string nowdate = DateTime.Now.ToString(); nowdate = nowdate.Replace(":", "").Replace(" ", "").Replace("-", "").Trim(); Random r = new Random(); int a = r.Next(1000); filename = nowdate + a.ToString() + Type; newFileName = filename; } else { filename = fu.FileName; if (System.IO.File.Exists(path + filename)) { erorr = "此文件名已經存在！"; return erorr; } } fu.SaveAs(path + filename); return erorr;//返回有錯的錯誤信息，沒有錯誤返回null } #endregion
