[wuyq11]

Bitmap bmp = new Bitmap(filePath);

bmp.Save("", ImageFormat.Bmp);

[cmsong]

wuyq11哥们能具体点嘛，感觉你给的解决方法不好用呢！

请问你的filePath指的是什么？chart没有保存成功啊，如果保存成功，问题就简单了！

[吃饭睡觉打小白]

Bitmap bmp = new Bitmap(@"f:\picture\temp.jpg");
bmp.Save("temp.bmp", ImageFormat.bmp);

[shin1105]

现在我懂了，非常简单，代码如下：


private void Save_Click(object sender, System.EventArgs e)
{
// Create a new save file dialog
SaveFileDialog saveFileDialog1 = new SaveFileDialog();

// Sets the current file name filter string, which determines
// the choices that appear in the "Save as file type" or
// "Files of type" box in the dialog box.
saveFileDialog1.Filter = "Bitmap (*.bmp)|*.bmp|JPEG (*.jpg)|*.jpg|EMF (*.emf)|*.emf|PNG (*.png)|*.png|SVG (*.svg)|*.svg|GIF (*.gif)|*.gif|TIFF (*.tif)|*.tif";
saveFileDialog1.FilterIndex = 2 ;
saveFileDialog1.RestoreDirectory = true ;

// Set image file format
if(saveFileDialog1.ShowDialog() == DialogResult.OK)
{
ChartImageFormat format = ChartImageFormat.Bmp;

if( saveFileDialog1.FileName.EndsWith( "bmp" ) )
{
format = ChartImageFormat.Bmp;
}
else if( saveFileDialog1.FileName.EndsWith( "jpg" ) )
{
format = ChartImageFormat.Jpeg;
}
else if( saveFileDialog1.FileName.EndsWith( "emf" ) )
{
format = ChartImageFormat.Emf;
}
else if( saveFileDialog1.FileName.EndsWith( "gif" ) )
{
format = ChartImageFormat.Gif;
}
else if( saveFileDialog1.FileName.EndsWith( "png" ) )
{
format = ChartImageFormat.Png;
}
else if( saveFileDialog1.FileName.EndsWith( "tif" ) )
{
format = ChartImageFormat.Tiff;
}
else if( saveFileDialog1.FileName.EndsWith( "svg" ) )
{
format = ChartImageFormat.Svg;
}

// Save image
Chart1.SaveImage( saveFileDialog1.FileName, format );
}
}

随便你保存哪种格式，给分吧

没有具体文件，有数据流也可以
Bitmap bmp = Bitmap.FromStream(Stream char1Stream);

bmp.Save("", ImageFormat.Bmp);

弹出来的保存对话框怎么会在页面底层呢？？？？？？？？？
