MemoryStream Constructor (Byte[], Boolean)

Initializes a new non-resizable instance of the MemoryStream class based on the specified byte array with the CanWrite property set as specified.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)
public MemoryStream(
	byte[] buffer,
	bool writable
)

Parameters

buffer
Type: System.Byte[]
The array of unsigned bytes from which to create this stream.
writable
Type: System.Boolean
The setting of the CanWrite property, which determines whether the stream supports writing.
ExceptionCondition
ArgumentNullException

buffer is null.

The CanRead and CanSeek properties are both set to true. Capacity is set to the length of the specified byte array.

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).

This constructor does not expose the underlying stream. GetBuffer throws UnauthorizedAccessException.
