Stream.Flush Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

When overridden in a derived class, clears all buffers for this stream and causes any buffered data to be written to the underlying device.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public MustOverride Sub Flush
public abstract void Flush()

Exceptions

Exception Condition
IOException

An I/O error occurs.

Remarks

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 Flush or Close method, which makes sure that the data is flushed to the underlying stream first and then written to the file.
