Microsoft Silverlight will reach end of support after October 2021. Learn more.
This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.
Provides access to unmanaged blocks of memory from managed code.

'Declaration Public Class UnmanagedMemoryStream _ Inherits Stream
public class UnmanagedMemoryStream : Stream
The UnmanagedMemoryStream type exposes the following members.
|CanRead||Infrastructure. Gets a value indicating whether a stream supports reading. (Overrides Stream.CanRead.)|
|CanSeek||Infrastructure. Gets a value indicating whether a stream supports seeking. (Overrides Stream.CanSeek.)|
|CanTimeout||Gets a value that determines whether the current stream can time out. (Inherited from Stream.)|
|CanWrite||Infrastructure. Gets a value indicating whether a stream supports writing. (Overrides Stream.CanWrite.)|
|Capacity||Infrastructure. Gets the stream length (size) or the total amount of memory assigned to a stream (capacity).|
|Length||Infrastructure. Gets the length of the data in a stream. (Overrides Stream.Length.)|
|Position||Infrastructure. Gets or sets the current position in a stream. (Overrides Stream.Position.)|
|PositionPointer||Infrastructure. Gets or sets a byte pointer to a stream based on the current position in the stream.|
|ReadTimeout||Gets or sets a value, in miliseconds, that determines how long the stream will attempt to read before timing out. (Inherited from Stream.)|
|WriteTimeout||Gets or sets a value, in miliseconds, that determines how long the stream will attempt to write before timing out. (Inherited from Stream.)|
|BeginRead||Begins an asynchronous read operation. (Inherited from Stream.)|
|BeginWrite||Begins an asynchronous write operation. (Inherited from Stream.)|
|Close||Closes the current stream and releases any resources (such as sockets and file handles) associated with the current stream. (Inherited from Stream.)|
|CopyTo(Stream)||Reads all the bytes from the current stream and writes them to the destination stream. (Inherited from Stream.)|
|CopyTo(Stream, Int32)||Reads all the bytes from the current stream and writes them to a destination stream, using a specified buffer size. (Inherited from Stream.)|
|Dispose()||Releases all resources used by the Stream. (Inherited from Stream.)|
|Dispose(Boolean)||Infrastructure. Releases the unmanaged resources used by the UnmanagedMemoryStream and optionally releases the managed resources. (Overrides Stream.Dispose(Boolean).)|
|EndRead||Waits for the pending asynchronous read to complete. (Inherited from Stream.)|
|EndWrite||Ends an asynchronous write operation. (Inherited from Stream.)|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)|
|Flush||Infrastructure. Overrides the Flush method so that no action is performed. (Overrides Stream.Flush().)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|Read||Infrastructure. Reads the specified number of bytes into the specified array. (Overrides Stream.Read(array<Byte, Int32, Int32).)|
|ReadByte||Infrastructure. Reads a byte from a stream and advances the position within the stream by one byte, or returns -1 if at the end of the stream. (Overrides Stream.ReadByte().)|
|Seek||Infrastructure. Sets the current position of the current stream to the given value. (Overrides Stream.Seek(Int64, SeekOrigin).)|
|SetLength||Infrastructure. Sets the length of a stream to a specified value. (Overrides Stream.SetLength(Int64).)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|Write||Infrastructure. Writes a block of bytes to the current stream using data from a buffer. (Overrides Stream.Write(array<Byte, Int32, Int32).)|
|WriteByte||Infrastructure. Writes a byte to the current position in the file stream. (Overrides Stream.WriteByte(Byte).)|
This class supports access to unmanaged memory using the existing stream-based model and does not require that the contents in the unmanaged memory be copied to the heap.
