c# - 字符串的最佳方法是什么？加入非字符串数组？

字符串的快捷方式是什么？加入第二个示例中的非字符串数组？

string[] names = { "Joe", "Roger", "John" };
Console.WriteLine("the names are {0}", String.Join(", ", names)); //ok

decimal[] prices = { 39.99M, 29.99m, 29.99m, 19.99m, 49.99m };
Console.WriteLine("the prices are {0}", String.Join(", ", prices)); //bad overload

最佳答案

如果您有LINQ:

decimal[] prices = { 39.99M, 29.99m, 29.99m, 19.99m, 49.99m };
Console.WriteLine("the prices are {0}",
    String.Join(", ",
       prices.Select(p => p.ToString()).ToArray()
    )
);
