Unity doesn’t have Stream’s CopyTo function? Really? Am I wrong or is that ridiculous?
Assets/Scripts/Utilities/Gzip.cs(22,49): error CS1061: Type System.IO.Compression.GZipStream' does not contain a definition for CopyTo’ and no extension method CopyTo' of type System.IO.Compression.GZipStream’ could be found (are you missing a using directive or an assembly reference?)

int num;
byte[ ] buffer = new byte[4096];
while ((num = src.Read(buffer, 0, buffer.Length)) != 0)
dest.Write(buffer, 0, num);
CopyTo: For when the above code isn’t good enough.
You can’t just call a library from nothing, you have to include it with a include call, or using call etc. etc. otherwise if you know the root of it you can do something like.
using System;
using System.IO;
using System.IO.Compression;
public static class Gzip {
public static byte[ ] Compress(byte[ ] bytes) {
using (MemoryStream iStream = new MemoryStream(bytes)) {
using (MemoryStream oStream = new MemoryStream()) {
using (GZipStream cStream = new GZipStream(oStream, CompressionMode.Compress)) {
iStream.CopyTo(cStream);
return oStream.GetBuffer();
}
}
}
}
public static byte[ ] Decompress(byte[ ] bytes) {
using (MemoryStream iStream = new MemoryStream(bytes)) {
using (MemoryStream oStream = new MemoryStream()) {
using (GZipStream dStream = new GZipStream(iStream, CompressionMode.Decompress)) {
dStream.CopyTo(oStream);
return oStream.GetBuffer();
}
}
}
}
}
I know.
If it were a static class, I would need to reference the namespace as you say. It’s not static. It’s a part of the stream, so it’s only important that the stream declaration includes the namespace.
If you notice, I have the ‘using’ declaration at the top. If that were the issue, then the original declaration wouldn’t work.
Also, I know this code works because I’m using the same class in my Visual C# project. The CopyTo declaration is missing in whatever .NET version Unity uses.
