MemoryStream.Write Method

.NET Framework 1.1

Writes a block of bytes to the current stream using data read from buffer.

[Visual Basic]
Overrides Public Sub Write( _
   ByVal buffer() As Byte, _
   ByVal offset As Integer, _
   ByVal count As Integer _
)
[C#]
public override void Write(
 byte[] buffer,
 int offset,
 int count
);
[C++]
public: void Write(
 unsigned char buffer __gc[],
 int offset,
 int count
);
[JScript]
public override function Write(
   buffer : Byte[],
 offset : int,
 count : int
);

Parameters

buffer: The buffer to write data from.
offset: The byte offset in buffer at which to begin writing from.
count: The maximum number of bytes to write.

Exceptions

Exception Type	Condition
ArgumentNullException	buffer is a null reference (Nothing in Visual Basic).
NotSupportedException	The stream does not support writing. For additional information see CanWrite. -or- The current position is closer than count bytes to the end of the stream, and the capacity cannot be modified.
ArgumentException	offset subtracted from the buffer length is less than count.
ArgumentOutOfRangeException	offset or count are negative.
IOException	An I/O error occurs.
ObjectDisposedException	The current stream instance is closed.

Remarks

For an example of creating a file and writing text to a file, see Writing Text to a File. For an example of reading text from a file, see Reading Text from a File. For an example of reading from and writing to a binary file, see Reading and Writing to a Newly Created Data File.

This method overrides Write.

The offset parameter gives the offset of the first byte in buffer to write from, and the count parameter gives the number of bytes to write. If the write operation is successful, the current position within the stream is advanced by the number of bytes written. If an exception occurs, the current position within the stream is unchanged.

Except for a MemoryStream constructed with a byte[] parameter, write operations at the end of a MemoryStream expand the MemoryStream.

Example

[Visual Basic, C#, C++] This code example is part of a larger example provided for the MemoryStream class.

[Visual Basic] 
' Write the first string to the stream.
memStream.Write(firstString, 0 , firstString.Length)

[C#] 
// Write the first string to the stream.
memStream.Write(firstString, 0 , firstString.Length);

[C++] 
// Write the first string to the stream.
memStream->Write(firstString, 0 , firstString->Length);
