Stream.Write Method

Updated: December 2010

When overridden in a derived class, writes a sequence of bytes to the current stream and advances the current position within this stream by the number of bytes written.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)
public abstract void Write(
	byte[] buffer,
	int offset,
	int count
)

Parameters

buffer
Type: System.Byte[]

An array of bytes. This method copies count bytes from buffer to the current stream.

offset
Type: System.Int32

The zero-based byte offset in buffer at which to begin copying bytes to the current stream.

count
Type: System.Int32

The number of bytes to be written to the current stream.

For an example of creating a file and writing text to a file, see How to: Write Text to a File. For an example of reading text from a file, see How to: Read Text from a File. For an example of reading from and writing to a binary file, see How to: Read and Write to a Newly Created Data File.

Use the CanWrite property to determine whether the current instance supports writing.

If the write operation is successful, the position within the stream advances by the number of bytes written. If an exception occurs, the position within the stream remains unchanged.
