MemoryStream Constructor (Byte, Int32, Int32, Boolean, Boolean)
[Visual Basic] Public Sub New( _ ByVal buffer() As Byte, _ ByVal index As Integer, _ ByVal count As Integer, _ ByVal writable As Boolean, _ ByVal publiclyVisible As Boolean _ ) [C#] public MemoryStream( byte buffer, int index, int count, bool writable, bool publiclyVisible ); [C++] public: MemoryStream( unsigned char buffer __gc, int index, int count, bool writable, bool publiclyVisible ); [JScript] public function MemoryStream( buffer : Byte, index : int, count : int, writable : Boolean, publiclyVisible : Boolean );
- The array of unsigned bytes from which to create this stream.
- The index into buffer at which the stream begins.
- The length of the stream in bytes.
- The setting of the CanWrite property, which determines whether the stream supports writing.
- true to enable GetBuffer, which returns the unsigned byte array from which the stream was created; otherwise, false.
|ArgumentNullException||buffer is a null reference (Nothing in Visual Basic).|
|ArgumentOutOfRangeException||index or count is negative.|
|ArgumentException||The buffer length minus index is less than count.|
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.
The new stream instance can be written to, but the Capacity of the underlying byte array cannot be changed. The length of the stream cannot be set to a value greater than the initial length of the specified byte array; however, the stream can be truncated (see SetLength).
