Writes a subarray of characters to the stream.
Assembly: mscorlib (in mscorlib.dll)
Public Overrides Sub Write ( _ buffer As Char(), _ index As Integer, _ count As Integer _ )
Dim instance As StreamWriter Dim buffer As Char() Dim index As Integer Dim count As Integer instance.Write(buffer, index, count)
public override void Write( char[] buffer, int index, int count )
public: virtual void Write( array<wchar_t>^ buffer, int index, int count ) override
public override function Write( buffer : char[], index : int, count : int )
Parameters
- buffer
- Type: System.Char[]
A character array containing the data to write.
- index
- Type: System.Int32
The index into buffer at which to begin writing.
- count
- Type: System.Int32
The number of characters to read from buffer.
| Exception | Condition |
|---|---|
| ArgumentNullException |
buffer is null. |
| 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.

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