泛型的简单用法<T>

 1         private void Form1_Load(object sender, EventArgs e)
 2         {
 3             Print<string>("here");
 4             Print<int>(1222);
 5 
 6             GenericCollections<string> gcl = new GenericCollections<string>();
 7             gcl.Add("这是一个字符串的示例");
 8             DisplayResult<string>(gcl);
 9             GenericCollections<string> gcl2 = new GenericCollections<string>();
10             gcl2.Add(true.ToString());
11             DisplayResult<string>(gcl2);
12             Console.ReadLine();
13         }
14 
15         public void Print<T>(T argument)
16         {
17             Console.WriteLine(argument.ToString());
18         }
19 
20         void DisplayResult<T>(GenericCollections<T> gcl)
21         {
22             foreach (T s in gcl)
23             {
24                 Console.WriteLine(s.ToString());
25             }
26         }
