C# 获取接口属性的运行时getter

声明：

interface I
{
    int i { get; set; }
}

class C : I
{
    public int i { get; set; }
}

代码：

嘿，

v1==v2

，

pi1！=pi2

，但显然调用了相同的方法。我如何在代码中知道

pi1

和

pi2

调用同一个方法体？

您可以使用它来获取特定类型的接口成员和实现成员之间的映射。下面是一个例子：

using System;
using System.Linq;
using System.Threading;

interface I
{
    int Value { get; set; }
}

class C : I
{
    public int Value { get; set; }
}

public class Test
{
    static void Main()
    {
        var interfaceGetter = typeof(I).GetProperty("Value").GetMethod;
        var classGetter = typeof(C).GetProperty("Value").GetMethod;
        var interfaceMapping = typeof(C).GetInterfaceMap(typeof(I));

        var interfaceMethods = interfaceMapping.InterfaceMethods;
        var targetMethods = interfaceMapping.TargetMethods;
        for (int i = 0; i < interfaceMethods.Length; i++)
        {
            if (interfaceMethods[i] == interfaceGetter)
            {
                var targetMethod = targetMethods[i];
                Console.WriteLine($"Implementation is classGetter? {targetMethod == classGetter}");
            }
        }
    }
}

---

。。。然后它将打印

实现是classGetter吗？错误

只是猜测而已。您是否尝试过：

pi1.DeclaringType==pi2.DeclaringType&&pi1.Name==pi2.Name

？@itsme86

DeclaringType

不同：

I

和

C

。

using System;
using System.Linq;
using System.Threading;

interface I
{
    int Value { get; set; }
}

class C : I
{
    public int Value { get; set; }
}

public class Test
{
    static void Main()
    {
        var interfaceGetter = typeof(I).GetProperty("Value").GetMethod;
        var classGetter = typeof(C).GetProperty("Value").GetMethod;
        var interfaceMapping = typeof(C).GetInterfaceMap(typeof(I));

        var interfaceMethods = interfaceMapping.InterfaceMethods;
        var targetMethods = interfaceMapping.TargetMethods;
        for (int i = 0; i < interfaceMethods.Length; i++)
        {
            if (interfaceMethods[i] == interfaceGetter)
            {
                var targetMethod = targetMethods[i];
                Console.WriteLine($"Implementation is classGetter? {targetMethod == classGetter}");
            }
        }
    }
}

interface I
{
    int Value { get; set; }
}

class Foo : I
{
    public int Value { get; set; }
}

class C : Foo
{
    public int Value { get; set; }
}
