C# Class OpenSyno.Services.ReadWriteMemoryStream

A memory stream with the ability to write data at the end of it while reading at an arbitrary position.

Only the Read and Write method were implemented. This stream can be typically used to start using the first chunks of data of a file before it is completely downloaded, when it is located on a slow link. Example : Start playing an mp3 file before it is completely downloaded.

Inheritance: System.IO.MemoryStream

Write() public method

Writes a block of bytes to the current stream using data read from buffer.

is null. The stream does not support writing. For additional information see .-or- The current position is closer than bytes to the end of the stream, and the capacity cannot be modified. subtracted from the buffer length is less than . or are negative. An I/O error occurs. The current stream instance is closed.
