StreamWriter.Write Method (Char[], Int32, Int32)

Writes a subarray of characters to the stream.

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

public override void Write (
	char[] buffer,
	int index,
	int count
)
public void Write (
	char[] buffer, 
	int index, 
	int count
)
public override function Write (
	buffer : char[], 
	index : int, 
	count : int
)
Not applicable.

Parameters

buffer

A character array containing the data to write.

index

The index into buffer at which to begin writing.

count

The number of characters to read from buffer.

Exception typeCondition

ArgumentNullException

buffer is a null reference (Nothing in Visual Basic).

ArgumentException

The buffer length minus index is less than count.

ArgumentOutOfRangeException

index or count is negative.

IOException

An I/O error occurs.

ObjectDisposedException

AutoFlush is true or the StreamWriter buffer is full, and current writer is closed.

NotSupportedException

AutoFlush is true or the StreamWriter buffer is full, and the contents of the buffer cannot be written to the underlying fixed size stream because the StreamWriter is at the end the stream.

This method overrides TextWriter.Write.

The characters are read from buffer beginning at index and continuing through index + (count - 1). All characters are written to the underlying stream unless the end of the underlying stream is reached prematurely. Flush is invoked automatically if AutoFlush is true.

For a list of common I/O tasks, see Common I/O Tasks.

This example writes eight characters from a 13-element array to a file, beginning at the third element of the array.
