Image.Save Method (String)
Saves this Image to the specified file or stream.
Assembly: System.Drawing (in System.Drawing.dll)
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.

The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
