学步园

看了下建哥的用反射生成的数组(http://blog.csdn.net/ojlovecd/archive/2008/11/11/3277766.aspx)

感觉不错,学习下,

(1)第一个例子是

public MethodInfo GetMethod(string name, Type[] types)

代码如下

using System;<br /> using System.Collections.Generic;<br /> using System.Text;<br /> using System.Reflection;<br /> namespace ConsoleApplication2<br /> {<br /> class Method<br /> {<br /> public void MethodA(int i, int j) { }</p> <p> public void MethodA(int i) { }</p> <p> public void MethodA(ref int r) {}</p> <p> static void Main()<br /> {<br /> MethodInfo MInfo;<br /> //用GetMethod调用method类中Method(int i,int j)中的方法,new Type[] {...对应MethodA()方法中参数}<br /> MInfo = typeof(Method).GetMethod("MethodA", new Type[] { typeof(int),typeof(int)});</p> <p> Console.WriteLine(MInfo.Name);</p> <p> MInfo = typeof(Method).GetMethod("MethodA", new Type[] {typeof(int) });</p> <p> Console.WriteLine(MInfo.Name);</p> <p> MInfo = typeof(Method).GetMethod("MethodA", new Type[] { typeof(int).MakeByRefType() });</p> <p> Console.WriteLine(MInfo.Name);<br /> }<br /> }<br /> }<br />

第二个例子是

MethodBase..::.Invoke 方法 (Object, array<Object>[]()[])

代码如下

using System;<br /> using System.Collections.Generic;<br /> using System.Text;<br /> using System.Reflection;<br /> namespace ConsoleApplication2<br /> {</p> <p> public class A<br /> {<br /> public void Area(int i, int j)<br /> {<br /> Console.WriteLine("Results:{0}", i * j);<br /> }<br /> }<br /> public class B<br /> {<br /> public void Min(int i, int j)<br /> {<br /> Console.WriteLine("Results:{0}", i + j);<br /> }<br /> }<br /> class InvokeInfo<br /> {<br /> static void Main()<br /> {<br /> A MyA = new A();<br /> B MyB = new B();</p> <p> Type TypeA = Type.GetType("ConsoleApplication2.A");//或者是Type TypeA = typeof(A);</p> <p> MethodInfo MethodInfoa = TypeA.GetMethod("Area");</p> <p> Type TypeB = Type.GetType("ConsoleApplication2.B");<br /> MethodInfo MethodInfob = TypeB.GetMethod("Min");<br /> Console.WriteLine("Type Name:{0}{1}", TypeA.FullName, MethodInfoa.Invoke(MyA,new Object[] { 10, 12 }));</p> <p> Console.WriteLine("Type Name:{0}{1}", TypeB.FullName, MethodInfob.Invoke(MyB, new Object[] { 12, 13 }));</p> <p> }<br /> }<br /> }<br />

 其实GetMethod(string name, Type[] types)返回的是MethodInfo对象

代码一中

Method M = new Method();<br /> MInfo = typeof(Method).GetMethod("MethodA", new Type[] { typeof(int), typeof(int) });</p> <p> Console.WriteLine(MInfo.Name);<br /> //调用InVoke方法,Invoke(object obj,[] object param)第二个参数是一个对象数组<br /> MInfo.Invoke(M, new Object[] { 3, 4 });<br />

未完.....
