上传图片和显示的问题 [英] problem with Upload picture and display

问题描述

嗨。



我写了以下代码用于上传图片然后立即显示，

Hi.

I have written the following code for uploading the image and then dispaly it instantly,

protected void SendImageButton_Click(object sender, EventArgs e)
        {
            string ImageName = FileUpload.FileName.ToString();
            string ImagePath = "/~ImageStorage/" + ImageName;
            FileUpload.SaveAs(Server.MapPath(ImagePath));

            int ImageSize = FileUpload.PostedFile.ContentLength;

            if (FileUpload.PostedFile != null && FileUpload.PostedFile.FileName != "")
            {
                SqlCommand Command = DataProvider.GenerateCommand("[dbo].[Insert_UploadPicture_SP]", CommandType.StoredProcedure);
                Command.Parameters.AddWithValue("@IdCode", GlobalVariables.IdCode);
                Command.Parameters.AddWithValue("@ImagePath", ImagePath);
                Command.Parameters.AddWithValue("@ImageName", ImageName);
                Command.Parameters.AddWithValue("@ImageSize", ImageSize);

                try
                {
                    Command.Connection.Open();
                    Command.ExecuteNonQuery();
                    Command.Connection.Close();
                }
                catch (Exception ex)
                {
                    EventLogger.Log(ex.Message, LogType.Error);
                }
                finally
                {
                    DataProvider.DisposeCommand(Command);
                }
            }

        }

但当我按下发送按钮时会抛出此异常：



DirectoryNotFoundException未被用户代码处理。

找不到路径的一部分''E：\ BackUp \VisualStudio2010\Marashi910816\Marashi \〜ImageStorage\Lighthouse.jpg''。



你能告诉我如何修改代码以立即显示图像？因为这个图像既不插入也不显示。

but when i press the Send button this exception is thrown :

DirectoryNotFoundException was unhandled by user code.
Could not find a part of the path ''E:\BackUp\VisualStudio2010\Marashi910816\Marashi\~ImageStorage\Lighthouse.jpg''.

and would you please tell me how can i modify the code to display the image instantly? becacuse this image neither is inserted and nor is displayed.
