Dictionary<string, string[]> 的 C# 对象初始值设定项应该是什么样的？

Question

我正在尝试声明一个值为字符串数组的字典。我该怎么做？

我尝试了以下代码（不起作用）：

Dictionary<string, string[]> NewDic = new Dictionary<string,string[]>
{
    {"Key_0", {"Value_0.0", "Value_0.1"}},
    {"Key_1", {"Value_1.0", "Value_1.1", "Value_1.2"}},
}

Answer 1

您需要指定您的值是数组，如：

使用implicitly typed array

 {"Key_0", new[] {"Value_0.0", "Value_0.1"}},

或明确指定类型

 {"Key_0", new string[] {"Value_0.0", "Value_0.1"}},

所以你的 class 可能看起来像：

public static class NewClass
{
    private static Dictionary<string, string[]> NewDic = new Dictionary<string, string[]>
    {
        {"Key_0", new[] {"Value_0.0", "Value_0.1"}},
        {"Key_1", new string[] {"Value_1.0", "Value_1.1", "Value_1.2"}},
    };
}
