Is typedef available in C# ?

No. C# contains no direct equivalent of the C++ typedef keyword. However, C# does feature an alias specified with the using keyword as in the following example:

using ByteList = System.Collections.Generic.List<byte>;

The scope of the alias is limited to the file in which it is declared. Some applications can use inheritance to get around this limitation as in the following example:

public class ByteList : List<byte> {}
