反射帮助-基于另一个对象在对象上设置属性 [英] Reflection Help - Set properties on object based on another object

问题描述

我可以使用一些帮助.我正在将一个对象传递给另一个对象的构造函数.我需要遍历参数的属性并基于它设置新的对象属性.大多数(但不是全部)params属性存在于新对象中.

I could use a bit of relection help. I am passing an object into the constructor of another object. I need to loop through the parameter's properties and set the new objects properties based on it. Most, but not all, of the params properties exist in the new object.

到目前为止，我已经有了基本骨架.

I have this so far, the basic skeleton.

  public DisabilityPaymentAddEntity(DisabilityPaymentPreDisplayEntity preDisplay)
  {
      Init(preDisplay);
  }

  private void Init(DisabilityPaymentPreDisplayEntity display)
  {
       //need some type of loop using reflection here
  }

在'Init'方法中，我需要遍历'display'的属性，并将任何同名的'DisabilityPaymentAddEntity'属性设置为preDisplay中的值.

In the 'Init' method, I need to loop through 'display's properties and set any of 'DisabilityPaymentAddEntity' properties of the same name to values in the preDisplay.

谁能给我一个线索，我需要做什么?我确定我需要使用PropertyInfo等.

Can anyone give me a clue what I need to do? I am sure I need to use PropertyInfo etc..

谢谢， 圣地亚哥〜ck

推荐答案

我认为这样的事情

Type target = typeof(DisabilityPaymentAddEntity);
foreach(PropertyInfo pi in display.GetType().GetProperties())
{
     PropertyInfo targetProp = target.GetProperty(pi.Name);
     if(targetProp!=null)
     {
        targetProp.SetValue(this, pi.GetValue(display, null), null);
     }
}
