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.
