Dear Friends,

Where as he/she will be uploading the file with any name.
But while storing it in a folder I have to rename the file with respective User''s ID.
I want to do this in C#, Kindly guide me.

推荐答案

这很容易做到.上载文件后，获取文件扩展名并将其另存为所需名称.请检查下面的示例代码.让Uploader作为您的文件上传控件ID.

Hi,
It is very easy to do. When the file is uploaded, get the extension of the file and save it as with your desired name. Please check the sample code below. Let Uploader be your fileupload control ID.

if (Uploader.HasFile)
        {
            string extension = Path.GetExtension(Uploader.PostedFile.FileName);
            Uploader.SaveAs(uploadFolder + "NewFileName"+ extension);
            labelfile.Text = "File uploaded successfully as: " + "NewFileName"+ extension;
        }

希望对您有帮助..编码愉快..:)

Hope it helps.. Happy coding.. :)

您可以在上传到文件夹中时实现此功能-


这样，您可以使文件名唯一，并使用用户名

Hi you can achieve this while uploadin to your folder -


by this you can make your file name unique and with your username

if (ASPxUploadControl1.HasFile ) or//(Fileupload.Hasfile)
 {
     try
     {
         string extension = Path.GetExtension(ASPxUploadControl1.FileName);
         string id = Guid.NewGuid().ToString();  //here give your username or whatever you want
         string fileLocation = string.Format("{0}/{1}{2}", Server.MapPath("upload/"), id, extension);
         ASPxUploadControl1.SaveAs( fileLocation );
         StatusLabel.Text = "Upload status: File uploaded!";
     }
     catch (Exception ex)
     {
         StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " + ex.Message;
     }
 }
