mvc3 上传图片

浏览数：23 / 时间：2015年06月09日

这是在Control里使用的代码，是在后台管理需要上传图片时使用的，不过我在这犯了一个错误， Request.Files[inputName];inputName名字中的大小写
<input type="file" name="image">应该与model里的字段的名字一致
if (Request.RequestType == "POST")
            {
                foreach (string inputName in Request.Files.AllKeys)
                {
                    HttpPostedFileBase file = Request.Files[inputName];
                    //存入文件
                    if (file.ContentLength > 0)
                    {
                        PropertyInfo pro = model.GetType().GetProperty(inputName);
                        string proValue = (string)pro.GetValue(model, null);
                        if (!string.IsNullOrWhiteSpace(proValue))
                        {
                            Common.FileUpload.DeleteFile(proValue);

                        }
                        string fileName = Common.FileUpload.UploadFile(file);
                        pro.SetValue(model, fileName, null);
                    }
                }
}

   public static string UploadFile(HttpPostedFileBase file)
       {

           // Check if we have a file

           if (null == file) return "";

           // Make sure the file has content

           if (!(file.ContentLength > 0)) return "";

           string fileName = file.FileName;

           string fileExt = Path.GetExtension(file.FileName);

           // Make sure we were able to determine a proper

           // extension

           if (null == fileExt) return "";
           char DirSeparator = ‘/‘;
           string FilesPath = string.Format("{0}team{0}{1}{0}{2}{3}{0}", DirSeparator, DateTime.Now.Year, DateTime.Now.Month.ToString().PadLeft(2, ‘0‘), DateTime.Now.Day.ToString().PadLeft(2, ‘0‘));
           string PhysicalPath = HttpContext.Current.Server.MapPath(FilesPath);
           // Check if the directory we are saving to exists

           if (!Directory.Exists(PhysicalPath))
           {

               // If it doesn‘t exist, create the directory

               Directory.CreateDirectory(PhysicalPath);

           }

           // Set our full path for saving

           string path = PhysicalPath + fileName;

           // Save our file

           file.SaveAs(Path.GetFullPath(path));

           // Return the filename

           return FilesPath + fileName;

       }

       public static void DeleteFile(string fileName)
       {
           if (!string.IsNullOrWhiteSpace(fileName))
           {
               // Don‘t do anything if there is no name

               if (fileName.Length == 0) return;

               // Set our full path for deleting

               string path = HttpContext.Current.Server.MapPath(fileName);

               // Check if our file exists

               if (File.Exists(Path.GetFullPath(path)))
               {

                   // Delete our file

                   File.Delete(Path.GetFullPath(path));

               }
