C#自省

1、根据string,获取type。Type.GetType 方法,获取具有指定名称的 Type,执行区分大小写的搜索。

  

2、根据obj,获取type。Object.GetType 方法,获取当前实例的 Type。

  

int n1 = 12;int n2 = 82;long n3 = 12;Console.WriteLine("n1 and n2 are the same type: {0}",                  Object.ReferenceEquals(n1.GetType(), n2.GetType()));Console.WriteLine("n1 and n3 are the same type: {0}",                  Object.ReferenceEquals(n1.GetType(), n3.GetType()));// The example displays the following output://       n1 and n2 are the same type: True//       n1 and n3 are the same type: False

3、根据type,创建obj。Activator.CreateInstance 方法。

  

4、根据type,获取所有public 成员变量。Type.GetField 方法。

  

5、根据FieldInfo与string,设置obj的成员变量。FieldInfo.SetValue 方法。

  

6、根据obj,获取期成员变量类型。FieldInfo.FieldType 属性。

  

  结果为某个基元数据类型,如 String、Boolean 或 GUID。若要获取 FieldType 属性,请先获取 Type 类。 从 Type 获取 FieldInfo。 从 FieldInfo 获取 FieldType 值。

using System;using System.Reflection;// Make a field.public class Myfield{    private string field = "private field";}public class Myfieldinfo{    public static int Main()    {        Console.WriteLine ("\nReflection.FieldInfo");        Myfield Myfield = new Myfield();        // Get the type and FieldInfo.        Type MyType = typeof(Myfield);        FieldInfo Myfieldinfo = MyType.GetField("field",             BindingFlags.Instance|BindingFlags.NonPublic);        // Get and display the FieldType.        Console.Write ("\n{0}.", MyType.FullName);        Console.Write ("{0} - ", Myfieldinfo.Name);        Console.Write ("{0};", Myfieldinfo.GetValue(Myfield));        Console.Write ("\nFieldType = {0}", Myfieldinfo.FieldType);    return 0;    }}

7、获取所继承的接口。Type.GetInterfaces 方法。
