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

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

When it is called by trusted applications, writes a subarray of characters to the stream.

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

Syntax

'Declaration
Public Overrides Sub Write ( _
    buffer As Char(), _
    index As Integer, _
    count As Integer _
)

public override void Write(
    char[] buffer,
    int index,
    int count
)

Parameters

  • buffer
    Type: array<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.

Exceptions

Exception Condition
ArgumentNullException

buffer is nulla 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.

Remarks

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.

Platform Notes

Silverlight for Windows Phone Silverlight for Windows Phone

 StreamWriter.Write may throw IndexOutOfRangeException if the stream state becomes corrupted. On Silverlight for Windows Phone, the stream state may become corrupted if multiple threads write to or read from a stream object without using synchronization.
