.NET(C#)中new Dictionary(字典)初始化值(initializer默认值)

1、C# 4.0中指定默认值的方法

class StudentName
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int ID { get; set; }
}
    Dictionary students = new Dictionary()
    {
        { 111, new StudentName {FirstName="Sachin", LastName="Karnik", ID=211}},
        { 112, new StudentName {FirstName="Dina", LastName="Salimzianova", ID=317}},
        { 113, new StudentName {FirstName="Andy", LastName="Ruth", ID=198}}
    };
//C# 4.0Dictionary myDict =    new Dictionary { { "key1", "value1" },        { "key2", "value2" },        { "key3", "value3" }    };Dictionary> myDictList =    new Dictionary> { { "key1", new List () { "value1" } },        { "key2", new List () { "value2" } },        { "key3", new List () { "value3" } }    };

2、C# 6.0中指定默认值的方法

class StudentName
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int ID { get; set; }
}
   Dictionary students = new Dictionary () {
                [111] = new StudentName { FirstName = "Sachin", LastName = "Karnik", ID = 211 }, 
                [112] = new StudentName { FirstName = "Dina", LastName = "Salimzianova", ID = 317 }, 
                [113] = new StudentName { FirstName = "Andy", LastName = "Ruth", ID = 198 }
            };
//C# 6.0Dictionary dic =    new Dictionary {        ["key1"] = "value1",        ["key2"] = "value2",        ["key3"] = "value3"    };Dictionary> dicList =    new Dictionary> {        ["key1"] = new List () { "value1" },        ["key2"] = new List () { "value2" },        ["key3"] = new List () { "value3" }    };
