{
if(stream==null)
thrownewArgumentNullException("stream");
if(length<=0)
thrownewArgumentException("Length");
if(entropy==null)
thrownewArgumentNullException("entropy");
if(entropy.Length<=0)
thrownewArgumentException("Entropy");
varinBuffer=newbyte[length];
byte[]outBuffer;
//Readtheencrypteddatafromastream.
if(stream.CanRead)
{
stream.Read(inBuffer,0,length);
outBuffer=ProtectedData.Unprotect(inBuffer,entropy,scope);
}
else
{
thrownewIOException("Couldnotreadthestream.");
}
//Returnthelengththatwaswrittentothestream.
returnoutBuffer;
