Write file to memorystream c#

Thank you. Microsoft makes no warranties, express or implied, with respect to the information provided here. Writes the sequence of bytes contained in source into the current memory stream and advances the current position within this memory stream by the number of bytes written. The zero-based byte offset in buffer at which to begin copying bytes to the current stream.

The stream does not support writing. For additional information see CanWrite. The current position is closer than count bytes to the end of the stream, and the capacity cannot be modified. This code example is part of a larger example provided for the MemoryStream class. This method overrides Write. The offset parameter gives the offset of the first byte in buffer to write from, and the count parameter gives the number of bytes to write.

Of course you're right, AlexeiLevenkov, I had forgotten I'd done that refactoring. Isn't it more efficient to set Stream. DavidThielen, while it is more efficient to change position I prefer creation of new MemoryStream since it makes code more explicit and lets use normal using pattern to write data. Note that MemoryStream on existing buffer is very small object, so I think it is good price for correctly looking code.

And if performance is so critical for particular piece of code I would not use MemoryStream due to its memory re-allocation strategy. In playing with this, I got the following prototype to work: using System. Mvc; using NUnit. Sign up or log in Sign up using Google. Sign up using Facebook.
