Thanks for your answer but:

        string s = readln();
        auto i = to!int(s);
}

compiles but after i enter a number and press the enter key i get:

std.conv.ConvException@.\..\..\src\phobos\std\conv.d(1595): Can't

what's wrong?

readln() includes the trailing newline character in the resulting 
string. You can use std.string.strip to remove leading and trailing 
whitespace:

import std.stdio;
import std.conv;
import std.string;
void main()
{
    write("Insert number: ");
    string s = readln();
    auto i = to!int(strip(s));
}
