MemoryStream Constructor (Int32)

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

Initializes a new instance of the MemoryStream class with an expandable capacity initialized as specified.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Sub New ( _
    capacity As Integer _
)

public MemoryStream(
    int capacity
)

Parameters

  • capacity
    Type: System.Int32
    The initial size of the internal array in bytes.

Exceptions

Exception Condition
ArgumentOutOfRangeException

capacity is negative.

Remarks

The CanRead, CanSeek, and CanWrite properties are all set to true.

The capacity automatically increases when you use the SetLength method to set the length to a value larger than the capacity of the current stream. Except for a MemoryStream constructed with a byte[] parameter, write operations at the end of a MemoryStream expand the MemoryStream.

This constructor exposes the underlying stream that GetBuffer returns.
