Why must I Close() a file in C#?

Question

I know this might seem silly, but why does the following code only work if I Close() the file? If I don\'t close the file, the entire stream is not written.

Steps:

Answer 1

Because you are using a streamwriter and it doesn't flush the buffer until you Close() the writer. You can specify that you want the writer to flush everytime you call write by setting the AutoFlush property of the streamwriter to true.

Check out the docs. http://msdn.microsoft.com/en-us/library/system.io.streamwriter.aspx

If you want to write to a file without "closing", I would use:

System.IO.File
