直接从EXE文件运行时，SaveFileDialog无法正常工作 [英] SaveFileDialog not working when it is being run directly from the EXE file

问题描述

我正在用C＃制作加菲猫漫画浏览器。我有一个按钮，可以将屏幕上的漫画保存到计算机上。但是，当我从Visual C＃Express编译它时，它可以完美地保存。当我从目录运行exe文件时，我收到一条未处理的异常消息，指出GDI +中发生了一般错误。这是我的保存代码：

I am making a Garfield comic viewer in C#. I have a button that saves the comic on screen to the computer. However, when I compile it from Visual C# Express, it saves perfectly. When I run the exe file from the directory, I get an unhandled exception message stating "A generic error occurred in GDI+". Here is my saving code:

private void save_Click(object sender, EventArgs e)
{
     using (SaveFileDialog dialog = new SaveFileDialog())
     {
          dialog.Title = "Save Dialog";
          dialog.Filter = "Bitmap Images (*.bmp)|*.bmp|All files(*.*)|*.*";
          if (dialog.ShowDialog(this) == DialogResult.OK)
          {
              using (Bitmap bmp = new Bitmap(pictureBox1.Image.Width, pictureBox1.Image.Height))
              {
                   pictureBox1.DrawToBitmap(bmp, new Rectangle(0, 0, bmp.Width, bmp.Height));
                   pictureBox1.Image = new Bitmap(pictureBox1.Image.Width, pictureBox1.Image.Height);
                   pictureBox1.Image.Save("c://cc.Jpg");
                   bmp.Save(dialog.FileName);
                   pictureBox1.ImageLocation = "http://garfield.com/uploads/strips" + "/" + whole.ToString("yyyy-MM-dd") + ".jpg";
                   MessageBox.Show("Comic Saved.");
              }
          }
      }
 }

我该怎么办？

What can I do?

推荐答案

Win7上的C：的根目录只读给非管理员。试图创建一个文件会失败。



另外，为什么在这个地球上你在PictureBox上调用DrawToBitmap？它已经显示了一个位图，所以绝对没有理由这样做！

The root of C: on Win7 is readonly to non-Admins. Trying to create a file there will fail.

Also, WHY on this earth are you calling DrawToBitmap on the PictureBox?? It's already showing a Bitmap, so there's absolutely no reason to do this!
