上次搜狐的
面试人员问我
自动化测试里反射的应用。我当时不知道反射机制的具体应用。
回头看了一下，才终于明白了反射的定义。以前只知道是rename和得到当前的方法。
没有想到，竟然可以执行自动化操作。怪不得他们问我了。
研究了一下msdn。然后从里面提取了一个不错的小例子。对于理解反射非常有帮助。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Reflection;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
test1();
Console.ReadKey();
}
public static void test1()
{
// Loads an assembly using its file name.
Assembly a = Assembly.LoadFrom(@"F:\Documents and Settings\v-yahuan\Desktop\ttt\TestRun0501\WinApp\bin\Debug\WinApp.exe");
// Gets the type names from the assembly.
Type[] types2 = a.GetTypes();
foreach (Type t in types2)
{
Console.WriteLine(t.FullName);
foreach (MemberInfo m in t.GetMethods())
{
Console.WriteLine("methods " + m.Name);
}
}
Console.WriteLine();
}
public static void test2()
{
Type t = typeof(ConsoleApplication1.Program);
Console.WriteLine("Listing all the members (public and non public) of the {0} type", t);
// Lists static fields first.
FieldInfo[] fi = t.GetFields(BindingFlags.Static |
BindingFlags.NonPublic | BindingFlags.Public);
Console.WriteLine("// Static Fields");
PrintMembers(fi);
// Static properties.
PropertyInfo[] pi = t.GetProperties(BindingFlags.Static |
BindingFlags.NonPublic | BindingFlags.Public);
Console.WriteLine("// Static Properties");
PrintMembers(pi);
// Static events.
EventInfo[] ei = t.GetEvents(BindingFlags.Static |
BindingFlags.NonPublic | BindingFlags.Public);
Console.WriteLine("// Static Events");
PrintMembers(ei);
// Static methods.
MethodInfo[] mi = t.GetMethods(BindingFlags.Static |
BindingFlags.NonPublic | BindingFlags.Public);
Console.WriteLine("// Static Methods");
PrintMembers(mi);
// Constructors.
ConstructorInfo[] ci = t.GetConstructors(BindingFlags.Instance |
BindingFlags.NonPublic | BindingFlags.Public);
Console.WriteLine("// Constructors");
PrintMembers(ci);
// Instance fields.
fi = t.GetFields(BindingFlags.Instance | BindingFlags.NonPublic |
BindingFlags.Public);
Console.WriteLine("// Instance Fields");
PrintMembers(fi);
// Instance properites.
pi = t.GetProperties(BindingFlags.Instance | BindingFlags.NonPublic |
BindingFlags.Public);
Console.WriteLine("// Instance Properties");
PrintMembers(pi);
// Instance events.
ei = t.GetEvents(BindingFlags.Instance | BindingFlags.NonPublic |
BindingFlags.Public);
Console.WriteLine("// Instance Events");
PrintMembers(ei);
// Instance methods.
mi = t.GetMethods(BindingFlags.Instance | BindingFlags.NonPublic
| BindingFlags.Public);
Console.WriteLine("// Instance Methods");
PrintMembers(mi);
Console.WriteLine("\r\nPress ENTER to exit.");
Console.Read();
}
public static void PrintMembers(MemberInfo[] ms)
{
foreach (MemberInfo m in ms)
{
Console.WriteLine("{0}{1}", " ", m);
}
Console.WriteLine();
}
}
}
