递归获取类的所有属性 C# [英] Get all properties of a class recursively C#

问题描述

我有一个看起来像

public class Employee
{
    public string FirstName { get; set; };
    public string LastName { get; set; }; 
    public Address Address { get; set; };  
}

public class Address 
{
    public string HouseNo { get; set; };
    public string StreetNo { get; set; }; 
    public SomeClass someclass { get; set; }; 
}

public class SomeClass 
{
    public string A{ get; set; };
    public string B{ get; set; }; 
}

我已经找到了一种使用反射在类中找出原始属性的方法，例如字符串、int bool 等

I have figured out a way finding out Properties in a class which are primitive like the string, int bool etc using Reflection

但我还需要找出一个类中所有复杂类型的列表，例如 for ex.类 Address 与类 Employee 和类 SomeClass 内的 Address

But I also need to find out the list of all complex types in a class like for ex. class Address withing Class Employee and class SomeClass within Address

推荐答案

如果您已经知道如何使用反射，这应该很容易:

If you already know how to use reflection, this should be easy:

private List<Type> alreadyVisitedTypes = new List<Type>(); // to avoid infinite recursion
public static void PrintAllTypes(Type currentType, string prefix)
{
    if (alreadyVisitedTypes.Contains(currentType)) return;
    alreadyVisitedTypes.Add(currentType);
    foreach (PropertyInfo pi in currentType.GetProperties())
    {
        Console.WriteLine($"{prefix} {pi.PropertyType.Name} {pi.Name}");
        if (!pi.PropertyType.IsPrimitive) PrintAllTypes(pi.PropertyType, prefix + "  ");
    }
}

还有这样的电话

PrintAllTypes(typeof(Employee), string.Empty);

会导致:

String FirstName
  Char Chars
  Int32 Length
String LastName
Address Address
  String HouseNo
  String StreetNo
  SomeClass someclass
     String A
     String B
