MemoryStream Constructor (Int32)

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

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

new : 
        capacity:int -> MemoryStream

Parameters

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

ExceptionCondition
ArgumentOutOfRangeException

capacity is negative.

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.

This code example is part of a larger example provided for the MemoryStream class.

No code example is currently available or this language may not be supported.
