Question

How in D would I cast integer to string? Something like

int i = 15
string message = "Value of  i  is " ~ toString(i); // cast(string) i - also does not work

Google给我带来了如何使用探戈的答案, 但我想要Phobos版本。

import std.conv;

int i = 15;
string message = "Value of  i  is " ~ to!string(i);

或 format :

import std.string;
string message = format("Value of  i  is %s.", i);

int i = 15
string message = "Value of  i  is " ~ to!string(i);
