如何对字符串数组进行HardCode？

Question

我基本上想输入一个string[]，并且能够基于换行符执行foreach。我试过这样做，但我不相信这能行得通。

static string[] mystrings = {"here"+
"there"+
"mine"
}

我想要一次一次地找到它，然后再回来。这个是可能的吗？

Answer 1

您只需在花括号列表前面添加new[]或new string[]即可。使用逗号，而不是加号。如图所示

string[] mystrings = new[] { "here", "there", "mine" };

仅供参考，C#提供的new[]快捷方式是语法糖，它可以推断您特指的是new string[]。如果要创建混合类型的数组(如object数组)，则必须显式使用new object[]，否则C#编译器不会知道您所暗示的是哪种类型。这就是：

// Doesn't work, even though assigning to variable of type object[]
object[] myArgs = new[] { '\u1234', 9, "word", new { Name = "Bob" } };

// Works
object[] myArgs = new object[] { '\u1234', 9, "word", new { Name = "Bob" } };

// Or, as Jeff pointed out, this also works -- it's still commas, though!
object[] myArgs = { '\u1234', 9, "word", new { Name = "Bob" } };

// ...althouth this does not, since there is not indication of type at all
var myArgs = { '\u1234', 9, "word", new { Name = "Bob" } };

Answer 2

static string[] myStrings = new string[] { "one", "two", "three" };

foreach(string s in myStrings)
{
     Console.WriteLine(s);
}

Answer 3

static string[] items = new[] { "here", "there", "mine" };

然后

foreach (string item in items)
{
   System.Diagnostics.Debug.WriteLine(item);
}

但请记住，数组可以初始化一次，然后您就不能添加更多的项，我建议使用泛型列表List<string>。

IList<string> items = new List<string> { "one", "two", "three" };
