denizzzka:
immutable ubyte[] valueBin = cast(immutable(ubyte[])) toStringz(s); // s is string typeError: e2ir: cannot cast toStringz(s) of type immutable(char)* to type immutable(ubyte[])
One way to do it: import std.stdio; void main() { string s = "hello"; auto valueBin = cast(immutable ubyte[])s.dup; writeln(valueBin); } But what are you trying to do? Bye, bearophile
