本篇內容介紹了“ASP.NET上傳實例介紹”的有關知識，在實際案例的操作過程中，不少人都會遇到這樣的困境，接下來就讓小編帶領大家學習一下如何處理這些情況吧！希望大家仔細閱讀，能夠學有所成！
KindEditor是一個不錯的網頁在線編輯器，可是它只提供了asp，php，jsp上傳的類，沒有提供ASP.NET上傳的類。
ASP.NET上傳代碼：
using System;
using System.Globalization;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
public partial class Jscript_KindEditor_upload_cgi_upload : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//文件保存目錄路徑
string SavePath = "/Upload_Images/";
//文件保存目錄URL
string SaveUrl = "/Upload_Images/";
//上傳圖片類型
string[] ExtStr=new string[4];
ExtStr[0] = ".gif";
ExtStr[1] = ".jpg";
ExtStr[2] = ".png";
ExtStr[3] = ".bmp";
//圖片的***大小
int MaxSize = 100000;
//錯誤提示
string[] MsgStr = new string[3];
MsgStr[0] = "上傳文件大小超過限制.";
MsgStr[1] = "上傳文件擴展名是不允許的擴展名.";
MsgStr[2] = "上傳文件失敗\\n請重試.";
string imgWidth = Request.Form["imgWidth"];
string imgHeight = Request.Form["imgHeight"];
string imgBorder = Request.Form["imgBorder"];
string imgTitle = Request.Form["imgTitle"];
string imgAlign = Request.Form["imgAlign"];
string imgHspace = Request.Form["imgHspace"];
string imgVspace = Request.Form["imgVspace"];
HttpPostedFile imgFile = HttpContext.Current.Request.Files["imgFile"];
//獲得文件名
string FileName = System.IO.Path.GetFileName(imgFile.FileName);
if (FileName != "")
{
if (imgFile.ContentLength > MaxSize)
{
Alert(MsgStr[0]);
}
else
{
string fileExtension = System.IO.Path.GetExtension(FileName).ToLower();
if (CheckExt(ExtStr, fileExtension))
{
//重新為文件命名,時間毫秒部分+擴展名
string imgReName = "" + DateTime.Now.ToString("yyyy-MM-dd-HH-mm-ss-ffff",
DateTimeFormatInfo.InvariantInfo) + "" + fileExtension;//文件夾名
string imgFolderName=DateTime.Now.ToString
("yyyyMMdd",DateTimeFormatInfo.InvariantInfo);
try
{
if (!System.IO.Directory.Exists(@Server.MapPath
("" + SavePath + "" +imgFolderName + ""))){
//生成文件完整目錄

("" + SavePath + "" +imgFolderName + ""));}
