You can convert any pointer type to an array type using slicing.

import std.c.string;
char* cstr;
string dstr = cstr[0..strlen(cstr)];

 import std.c.string;
 char* cstr;
 string dstr = cstr[0..strlen(cstr)];

Or you can use std.string.toString().  It's cleaner, but slower because 
it copies the string.

To go the other way, use toStringz().  Or do dstr ~'\0'.

D string literals always have a null terminator appended so you can use 
them directly with C functions.

No is isn't, it does the exact same thing as what was posted above (cstr[0 
.. strlen(cstr)]).

Aaaaaaaargh!  It's toStringz that copies the string.  Can't remember the 
last time I was wrong about anything. :(

In my defence, phobos 2.0 toString(char*) does actually copy...

when you pass D char[] to windows API *char
you can use std.windows.charset.toMBSz()
