C# 创建 Hashtable、Dictionary、ArrayList 等对象的简写方法

这个问题也是别人问到的,下面贴出来供大家参考。

C# 代码
  public class Person
  {
    public String Name { set; get; }
    public int Age { set; get; }
    public String Url { set; get; }
  }


  protected void Page_Load(object sender, EventArgs e)
  {
    //Dictionary 的简写形式
    Dictionary<int, String> dict = new Dictionary<int, string>() { { 1, "A" }, { 2, "BB" } };
    foreach (KeyValuePair<int, String> d in dict)
    {
      Response.Write("<li>" + d.Key + " = " + d.Value);
    }

    //Hashtable 的简写形式www.zzzyk.com
    Hashtable myHash = new Hashtable() { { "key1", "AA" }, { "key2", "BB" } };
    foreach (DictionaryEntry d in myHash)
    {
      Response.Write("<li>" + d.Key + " = " + d.Value);
    }

    ArrayList ar = new ArrayList() { "A", "B", "C" };
    foreach (string d in ar)
    {
      Response.Write("<li>" + d);
    }

    //创建普通对象
    Person p = new Person() { Name = "net_lover", Age = 28, Url = "http://dotnet.aspx.cc" };
  }
