UploadFileName = FileUpload1.PostedFile.FileName;//文件在本地的原始位置

UploadFileLastName = UploadFileName.Substring(UploadFileName.LastIndexOf(".") + 1);//得到文件的扩展名

Random rd = new Random();//产生随机数

int valationNo = 10 + rd.Next(99);//产生随机数

string suiji = valationNo.ToString();//产生随机数

string UpLoadFileTime = DateTime.Now.ToString("yyyyMMddHHmmss") + suiji;//得到系统时间并加上随机数以便生成上传图片名称

string NewUploadFileName = UpLoadFileTime + "." + UploadFileLastName;//产生上传图片的名称

string UserDirectory = "TestFile";//所要创建文件夹的名字，实际运用中可为用户注册ID

string UserPath = Server.MapPath("UploadFiles").ToString() + "\\" + UserDirectory + "\\" + "ProductsImages";

if (!Directory.Exists(UserPath)) //如果文件夹不存在则创建

{

Directory.CreateDirectory(UserPath);

}

FileUpload1.PostedFile.SaveAs(NewUploadPahtName);//用保存的方法将图片上载

string sUser_ProductsImageUrl = "UploadFiles/" + UserDirectory + "/" + "ProductsImages/" + NewUploadFileName;//得到服务端图片的虚拟路径

//Response.Write(sUser_ProductsImageUrl);
