Question

请问一下C#的savedialog怎么保存图片呢？

我从网上参考了一下，保存到最后发现是个无效图片，谢谢
private void toolStripButton11_Click(object sender, EventArgs e)
{
string localFilPath, fileNameExt;
saveFileDialog1.Filter = "图片文件(*.jpg)|*.jpg";
saveFileDialog1.FilterIndex = 1;
saveFileDialog1.RestoreDirectory = true;
string strPath = saveFileDialog1.FileName;
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
if (saveFileDialog1.FileName != "")
{
localFilPath = saveFileDialog1.FileName.ToString();
fileNameExt = localFilPath.Substring(localFilPath.LastIndexOf("\\") + 1);
System.IO.FileStream fs = (System.IO.FileStream)saveFileDialog1.OpenFile();
SaveFile(); fs.Close();
}
}
}
public void SaveFile()
{ Image im = this.pictureBox1.Image;
Bitmap bit = new Bitmap(im);
bit.Save(Application.StartupPath + "\\hah.jpg",
System.Drawing.Imaging.ImageFormat.Bmp);
}

Answer 1

bit.Save(Application.StartupPath + "\\hah.jpg", System.Drawing.Imaging.ImageFormat.Bmp);

你这图片保存路径被强制指定到跟EXE程序同一目录下的 hah.jpg 里去了，而不是

System.IO.FileStream fs = (System.IO.FileStream)saveFileDialog1.OpenFile();

这个流所指向的地址。

追问
