What exactly do you mean by "binary"?  If you mean convert a string to a
numerical type, use std.conv.to:

        import std.conv : to;
        auto x = "12345";
        auto i = x.to!int;
        assert(i == 12345);

If you want to print a decimal string in binary:

        import std.stdio;
        auto x = "12345";
        auto i = x.to!int;
        writefln("%b",  i);     // prints: 11000000111001

Or if you want the binary representation in string form:

        import std.format : format;
        auto x = "12345";
        auto i = x.to!int;
        auto s = format("%b",  i);
        assert(s == "11000000111001");
