C# 自动实现属性

在这个代码片断中，Joseph 测试了一个使用 C# 反射来自动实现属性时，发生了一个意想不到行为的方案。之后提供了该方案的分步说明，他提供了示例项目最终输出的截图、相关的 C# 完整代码、Visual Studio 2008的项目下载。

Code

Listing 1: Employee.cs

using System;
namespace CompilerGeneratedProps
{
public class Employee : Person
{
//Fields
protected string Title;
}
}

Listing 2: Person.cs

using System;
namespace CompilerGeneratedProps
{
public class Person
{
//Fields
protected string _LastName; //Declared protected for extensibility.

//Properties
public string FirstName { get; set; } //Auto-implemented property.

public string LastName
{
get
{
return this._LastName;
}
set
{
this._LastName = value;
}
}
}
}

Listing 3: Program.cs

using System;
using System.Reflection;

namespace CompilerGeneratedProps
{
public class Program
{
static void Main(string[] args)
{
Console.WriteLine("Fields seen in an instance of Person");
Console.WriteLine("-------------------------------------------------------");

Person objPerson = new Person();
foreach (FieldInfo fi in
objPerson.GetType().GetFields(BindingFlags.Instance |
BindingFlags.NonPublic | BindingFlags.Public))
{
Console.WriteLine(fi.Name);
}

Console.WriteLine("\n\n\n\nFields seen in an instance of Employee");
Console.WriteLine("-------------------------------------------------------");

Employee objEmployee = new Employee();
foreach (FieldInfo fi in
objEmployee.GetType().GetFields(BindingFlags.Instance |
BindingFlags.NonPublic | BindingFlags.Public))
{
Console.WriteLine(fi.Name);
}
Console.Read();
}
}
}
