MemoryStream Constructor (array<Byte[], Boolean)

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

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)

Syntax

'Declaration
Public Sub New ( _
    buffer As Byte(), _
    writable As Boolean _
)

public MemoryStream(
    byte[] buffer,
    bool writable
)

Parameters

  • buffer
    Type: array<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.

Exceptions

Exception Condition
ArgumentNullException

buffer is nulla null reference (Nothing in Visual Basic).

Remarks

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.
