When overridden in a derived class, clears all buffers for this stream and causes any buffered data to be written to the underlying device.
Assembly: mscorlib (in mscorlib.dll)
Override Flush on streams that implement a buffer. Use this method to move any information from an underlying buffer to its destination, clear the buffer, or both. Depending upon the state of the object, you might have to modify the current position within the stream (for example, if the underlying stream supports seeking). For additional information see CanSeek.
When using the StreamWriter or BinaryWriter class, do not flush the base Stream object. Instead, use the class's or Close method, which makes sure that the data is flushed to the underlying stream first and then written to the file.
