This class acts like a MemoryStream but allows stream sizes over 2 GiB.
Usage is the same as a standard stream, though ToArray() should be avoided for large streams.
The intent is to use this in place of MemoryStream when serializing/deserializing large objects in memory.

Syntax
The CogMemoryStream type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
 | CogMemoryStream |
Methods
| Name | Description | |
|---|---|---|
| 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.) |
| CreateObjRef | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.) |
 | CreateWaitHandle | Obsolete. Allocates a WaitHandle object. (Inherited from Stream.) |
| Dispose | Releases all resources used by the Stream. (Inherited from Stream.) |
| Dispose(Boolean) | Releases the unmanaged resources used by the Stream and optionally releases the managed resources. (Inherited from Stream.) |
| EndRead | Waits for the pending asynchronous read to complete. (Inherited from Stream.) |
| EndWrite | Ends an asynchronous write operation. (Inherited from Stream.) |
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
| Finalize | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| Flush | (Overrides Stream Flush .) |
| FromSerializationInfo |
Retrieves an object from a series of 1 GiB arrays in the SerializationInfo
This is useful in serialization constructors when large objects need to be retrieved
|
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetLifetimeService | Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| InitializeLifetimeService | Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| MemberwiseClone(Boolean) | Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.) |
| ObjectInvariant | Provides support for a Contract. (Inherited from Stream.) |
| Read | (Overrides Stream Read( Byte , Int32, Int32).) |
| ReadByte | Reads a byte from the stream and advances the position within the stream by one byte, or returns -1 if at the end of the stream. (Inherited from Stream.) |
| Seek | (Overrides Stream Seek(Int64, SeekOrigin).) |
| SetLength | (Overrides Stream SetLength(Int64).) |
| ToSerializationInfo |
Stores an object as a series of 1GiB arrays in the SerializationInfo
This is useful in the GetObjectData method when large objects need to be stored
|
| ToString | Returns a String that represents the current Object. (Inherited from Object.) |
| Write | (Overrides Stream Write( Byte , Int32, Int32).) |
| WriteByte | Writes a byte to the current position in the stream and advances the position within the stream by one byte. (Inherited from Stream.) |
Properties
| Name | Description | |
|---|---|---|
 | CanRead | (Overrides Stream CanRead.) |
| CanSeek | (Overrides Stream CanSeek.) |
| CanTimeout | Gets a value that determines whether the current stream can time out. (Inherited from Stream.) |
| CanWrite | (Overrides Stream CanWrite.) |
| Length | (Overrides Stream Length.) |
| Position | (Overrides Stream Position.) |
| 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.) |
