How can I use a delegate that I can set to call a non static function
but of any instance of the class ?

eg

class TypeTeader<T>
{
delegate T readDelegate<T>();
readDelegate<T> ReadFunction;
public TypeTeader(readDelegate d)
{
ReadFunction=d;
}
public void read<T>(BinaryReader reader,ref T p)
{
//use the ReadFunction delegate to acces the relevant function of reader
}
}

TypeReader<Int32> Int32reader(/*pass ReadInt32 function of BinaryReader*/);

If I have understood what you want, I think that you can achieve it by means of a MethodInfo instead of a delegate:

using System.Reflection;
....
class TypeTeader<T>
{
MethodInfo ReadFunction;
public TypeReader(MethodInfo d)
{
ReadFunction=d;
}
public void read<T>(BinaryReader reader,ref T p)
{
p = (T)ReadFunction.Invoke(reader, null);
}
}
....
Type t = typeof(BinaryReader);
TypeReader<Int32> Int32reader = new TypeReader<Int32>(t.GetMethod("ReadInt32"));
