JPG和PNG图像已经被压缩，因此除非您准备降低图像质量，否则无法进一步减小文件大小.

Image.Save方法调用GDI +函​​数 GdipSaveImageToFile [

JPG and PNG images are already compressed, so you can''t reduce file size appreciably further unless you are prepared to lose image quality.

The Image.Save method calls GDI+ function GdipSaveImageToFile [^]with the encoderParams parameter set to null, which equates to 75%. You could use the function directly, supplying a "proper" parameter and change that to get a smaller file size, but the quality will suffer.

只需更改您在默认页面...这可能是权限问题...

Just change the path which you re giveing in the default page...this can be a permission issue...
