WebApr 13, 2011 · The CLR has a limit on the size of any particular object anyway (also around 2GB IIRC, even on a 64-bit CLR), so you couldn't have a byte array big enough for it to be a problem. You should always loop when reading anyway, as you can't guarantee that a Read call will read as many bytes as you requested, even if there's more data to come. it\u0027s all about the wood t shirtWebFeb 7, 2012 · 43. The natural way to get the file size in .NET is the FileInfo.Length property you mentioned.
