Image bitmap = Image.FromFile("C:\MyFile.bmp");

You should be able to use the Save Methodfrom the Image Classand be just fine as shown above. The Save Method has 5 different options or overloads...
您应该能够使用Image 类中的Save 方法，并且如上所示。Save 方法有 5 个不同的选项或重载...
//Saves this Image to the specified file or stream.
img.Save(filePath);
//Saves this image to the specified stream in the specified format.
img.Save(Stream, ImageFormat);
//Saves this Image to the specified file in the specified format.
img.Save(String, ImageFormat);
//Saves this image to the specified stream, with the specified encoder and image encoder parameters.
img.Save(Stream, ImageCodecInfo, EncoderParameters);
//Saves this Image to the specified file, with the specified encoder and image-encoder parameters.
img.Save(String, ImageCodecInfo, EncoderParameters);

SaveFileDialog sv = new SaveFileDialog();
sv.Filter = "Images|*.jpg ; *.png ; *.bmp";
ImageFormat format = ImageFormat.Jpeg;
if (sv.ShowDialog() == DialogResult.OK)
{
switch (sv.Filter )
{
case ".jpg":
format = ImageFormat.Png;
break;
case ".bmp":
format = ImageFormat.Bmp;
break;
}
pictureBox.Image.Save(sv.FileName, format);
}
