提取对象的价值？ [英] Extract value from Object?

问题描述

我想让我在其中传递的对象我做的任何实例动态方法，例如：

I wanted to make a dynamic method in which i pass any instance of object i made, for example:

public class Employee()
{
  public string FName;
  public string SName;
  .....etc.
}

我要的方法是这样的：

The method i want is like the following:

public void methodName(Object oObject)
{
  //lets say that i have passed object employee to it.
}

是否有可能从oObject提取任何价值，我试图这样做，但它没有属性，这样做，当我把手表，我可以实际上可以看到类别的雇员，所有的属性在里面。

Is it possible to extract any values from the oObject, i have tried to do so but it have no attributes to do so, and when i put in the watch i can acutally see all the attribute of class employee in it.

那么，有什么办法？

推荐答案

<击>有很多种方法。

更新：你说你要整个对象。 铸造或接口暴露的属性就是这样向前的。

Update: you say you want the whole object. Casting or interfaces to expose the properties is the way foward.

您可以把对象的具体类型：

You can cast the object to the specific type:

if (oObject is Employee)
{
    string name = (oObject as Employee).FName;
}

您可以公开定义方法的期望的接口，然后提供类型实现的接口：

You can expose an interface that defines what the method expects, then provided types implement the interface:

public interface IFirstName
{
    string FName { get; }
}

public void methodName(IFirstName objectWithFirstName)
{
    string name = objectWithFirstName.FName;
}

您可以使用动态，并希望最好在运行时（.NET 4）：

You can use dynamic and hope for the best at runtime (.NET 4):

public void methodName(dynamic oObject)
{
    string name = oObject.FName;
}

再有就是反思。

但更好的问题要问的是，这是一个好方法吗？我是有点怀疑关于采取任何方法，使事情的期待......虽然这并不是说，它不会或不应该发生的。

But the better question to ask is, is this a good method? I would be a little skeptical about methods that take anything and make expectations about things... though that's not to say it doesn't or shouldn't happen.
