如何遍历类属性树? [英] How to loop through class properties tree?

问题描述

class ClassA 
{
   public ClassB myProp {get;set;}
}

class ClassB 
{
   public ClassC anotherProp {get;set;}
}

class ClassC 
{
   public string Name {get;set;}
}

我有一个ClassA类型的对象.如何通过反射递归地迭代以获得ClassC的Name属性值?

I have an object of the ClassA type. How, by the reflection iterate recursively to get ClassC's Name property value ?

推荐答案

好的，解决了.假设我有要获取的值的属性的路径:

Ok, solved. Let's say that I have the path to the Property which value I wanna get:

ClassB.ClassC.Name

然后，在分割了parh之后，我无需递归就遍历了树；)

then, after splitting that parh I iterate through the tree without recursion ;)

var dataPath = column.SortMemberPath.Split(new char[] { '.' });

[...]

foreach (var item in (System.Collections.IList)myObject)
{
   var newItem = item;

   foreach (var path in dataPath)
   {
         var actalValue = newItem.GetType().GetProperty(path).GetValue(newItem, null);
         newItem = actalValue; //it does the trick
   }

   now, the newItem is my wanted property value 
}
