反射以获取 class 属性 在 class 中的值

Question

我有 2 种 class。

public class Info
{
 public string name {get; set;}
 public Address address {get; set;}
}

public class Address
{
 public string addressInfo {get;set;}
 public string country {get;set;}
}

**

Edit:

Info info = new Info();
string subClass="address"; 
Type subType = info .GetType().GetProperty(subClass).PropertyType;
string val = typeof(subType).GetType().GetProperty("addressInfo").GetValue(data, null)?.ToString() ?? "";

This is what I want to achieve but I cannot code in this way, cause it got error. **

现在我想通过Reflection 动态获取Address class 里面Info class 里面的addressInfo 的值。我怎样才能做到这一点？ 谢谢！！！

Answer 1

你可以试试

var info = new Info();

var property = info
   .GetType()
   .GetProperty("address");

string val = (string)property
   .PropertyType
   .GetProperty("addressInfo")
   .GetValue(property.GetValue(info));

_{注意 : 这个是缺少合适的错误校验和容错，酌情加盐}
