Type对象获得泛型类型的两个扩展方法

1、定义扩展对象

1:  public static class ExtendMethod

2:  {

3:   

4:      public static Type GetSingleGenericType(this Type t)

5:      {

6:          Type[] ts = GetGenericType(t);

7:          if (ts == null) return null;

8:          return ts[0];

9:      }

10:   

11:      public static Type[] GetGenericType(this Type t)

12:      {

13:          if (!t.IsGenericType) return null;

14:          List lt = new List();

15:          int begin = t.FullName.IndexOf('[');

16:          int end = t.FullName.LastIndexOf(']');

17:          string str = t.FullName.Substring(begin + 1, end - begin - 1);

18:          while(true)

19:          {

20:              begin = str.IndexOf('[');

21:              if (begin < 0) break;

22:              lt.Add(Type.GetType(str.Substring(begin + 1, str.IndexOf(',') - 1)));

23:              str = str.Remove(0, str.IndexOf(']') + 1);

24:              str = str.TrimStart(',');

25:          }

26:          return lt.ToArray();

27:      }

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

2、应用示例。

1:  Type type = typeof(Dictionary);

2:  Type[] tS = type.GetGenericType();

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

这时tS中分别的System.Int32和System.String的Type对象。
