MemoryStream Constructor (Int32)
.NET Framework (current version)
Initializes a new instance of the MemoryStream class with an expandable capacity initialized as specified.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- capacity
-
Type:
System.Int32
The initial size of the internal array in bytes.
| Exception | Condition |
|---|---|
| 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.
