asp.net-mvc-2 - 如何为字典提供硬编码值

Question

这是我的字典。

Dictionary<string, Test> test = new Dictionary<string, Test>();

在测试中，我有 Id、Name、Score。我想用硬编码值填充这些属性。(不止一个计数)。

如何给字典赋予静态值

我是否应该这样给予...

Dictionary<string, Test> test= new Dictionary<string, Test>();
Groups groups = new Groups();
groups.Id = "1";
groups.Name = "Name";
groups.Description = "Desc";
test.Add(groups.Id, groups);

Answer 1

您可以在 C#3 和 4 中使用集合初始化语法:

var data = new Dictionary<String,Object> {
  { "Foo", "Bax" },
  { "Bar", new DateTime(2010,10,10) },
  { "Xyzzy", 42 }
};

附加:更新后的问题代码:

Dictionary<string, Test> test= new Dictionary<string, Test>();
Groups groups = new Groups();
groups.Id = "1";
groups.Name = "Name";
groups.Description = "Desc";
test.Add(groups.Id, groups);

可以重写为单个表达式(同时注意值类型似乎是 Groups，并显示如何添加多个键值对):

Dictionary<string, Test> test= new Dictionary<string, Groups> {
  {
    "1", new Groups {
      Id = "1",
      Name = "Name",
      Description = "Desc"
    }
  }, {
    "2", new Groups {
      Id = "2",
      Name = "Another Name",
      Description = "Something        }
  }
};
