I made a program to take a screenshot of the screen. How can I save the image without prompting the user for imput?

A:
System.IO.File.WriteAllBytes(filePath, bytes) is what you are looking for. Give it a file path and some bytes, and it will write them to that file. Without seeing what image class you are working with, I can't tell you how to extract the bytes from it.
System.IO.File.WriteAllText(filePath, text) is also handy for writing text files if you need to do that.

That depends. If you want to save it to the Temp directory, you can call Path.GetTempFileName() to get a file name where you can save the file.
If there's a particular directory in which you want to save it, you can settle on a file naming convention like screenshot1, screenshot2, etc. Load the contents of the directory, find the next number in sequence, construct the filename, and save.

I'm asking about save part, not everything above.

A reason for the downvote would be appreciated. It seems like a valid answer to the question, as asked ... before he clarified that he knew where he wanted to save it.

I downvoted you because I asked how to save and you pretty much answered: "save it". I need to know the how of the 'saving' process.

I don't agree this should have been downvoted. The prime purpose of the SaveFileDialog is to allow the user to generate a filename for the file in question. Lack of a dialog implies you're getting the destination directory and filename from some other means, and Jim raises interesting points. This is really a bullshit question, because all you need to do is create a FileStream with the destination filename and appropriate flags. *what* that to use for the filename is the interesting point.

@Nathan: Read my question again and you'll see I asked how to save a file without prompting for path. The accepted answer does just that; I fail to see how this is a bullshit 'question'.

Actually, your question says, "without prompting the user for imput." Combined with your mention (in the question title) of not wanting SaveFileDialog displayed, I assumed you meant that you were looking for a way to automatically generate a file name.
