Namespace:  System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

public void Save(
	string filename
)

Parameters

filename
Type: System.String

A string that contains the name of the file to which to save this Image.

ExceptionCondition
ArgumentNullException

ExternalException

The image was saved with the wrong image format.

-or-

The image was saved to the same file it was created from.

If no encoder exists for the file format of the image, the Portable Network Graphics (PNG) encoder is used. When you use the Save method to save a graphic image as a Windows Metafile Format (WMF) or Enhanced Metafile Format (EMF) file, the resulting file is saved as a Portable Network Graphics (PNG) file. This behavior occurs because the GDI+ component of the .NET Framework does not have an encoder that you can use to save files as .wmf or .emf files.

Saving the image to the same file it was constructed from is not allowed and throws an exception.

The following code example demonstrates how to call the Save method. This example is designed to be used with Windows Forms. Create a form that contains two buttons named Button1 and Button5. Paste the code into the form, and associate each method with the corresponding button's Click event.

private void Button5_Click(System.Object sender, System.EventArgs e)
{
    try
    {
        if (image1 != null)
        {
            image1.Save("c:\\myBitmap.bmp");
            Button5.Text = "Saved file.";
        }
    }
    catch(Exception)
    {
        MessageBox.Show("There was a problem saving the file." +
            "Check the file permissions.");
    }

}
