C# 显示对象所有属性的全名

我有两门课：

public class Customer
{
    public string FirstName { get; set; }

    public string LastName { get; set; }

    public DateTime Date { get; set; }

    public bool isActif { get; set; }

    public Quantity Quantity { get; set; }
}

public class Quantity
{
    public string Color { get; set; }

    public int Number { get; set; }
}

还有一个方法，通过反射和递归显示我的类Customer的一个实例的所有属性：

public static void DisplayProperties(object objectA)
{
    if (objectA != null)
    {
        Type objectType;

        objectType = objectA.GetType();

        foreach (PropertyInfo propertyInfo in objectType.GetProperties(BindingFlags.Public | BindingFlags.Instance).Where(x => x.CanRead))
        {
            object valueA = propertyInfo.GetValue(objectA, null);

            if (typeof(IComparable).IsAssignableFrom(propertyInfo.PropertyType) || propertyInfo.PropertyType.IsPrimitive || propertyInfo.PropertyType.IsValueType)
            {
                Console.WriteLine(propertyInfo.ReflectedType.Name + "." + propertyInfo.Name);
            }
            else
                DisplayProperties(valueA);
        }
    }
}

结果是：

Customer.FirstName
Customer.LastName
Customer.Date
Customer.isActif
Quantity.Color
Quantity.Number

但我想恢复像那样的财产的全名

Customer.FirstName
Customer.LastName
Customer.Date
Customer.isActif
Customer.Quantity.Color
Customer.Quantity.Number

如何做？

一个好方法是在每次调用

DisplayProperties

时传递路径

更改方法签名：

public static void DisplayProperties(object objectA, string path = "")

改变印刷方法

Console.WriteLine("{0}{1}.{2}", path, propertyInfo.ReflectedType.Name, propertyInfo.Name);

DisplayProperties(valueA, objectA.GetType().Name + ".");

更改递归调用方法

Console.WriteLine("{0}{1}.{2}", path, propertyInfo.ReflectedType.Name, propertyInfo.Name);

DisplayProperties(valueA, objectA.GetType().Name + ".");

将您的

DisplayProperties

方法更改为

public static void DisplayProperties(object objectA, string objName="")
{
    if (objectA != null)
    {
        Type objectType;

        objectType = objectA.GetType();

        foreach (PropertyInfo propertyInfo in objectType.GetProperties(BindingFlags.Public | BindingFlags.Instance).Where(x => x.CanRead))
        {
            object valueA = propertyInfo.GetValue(objectA, null);

            if (typeof(IComparable).IsAssignableFrom(propertyInfo.PropertyType) || propertyInfo.PropertyType.IsPrimitive || propertyInfo.PropertyType.IsValueType)
            {
                Console.WriteLine(objName +  (objName==""? "" : ".") + propertyInfo.ReflectedType.Name + "." + propertyInfo.Name);
            }
            else
                DisplayProperties(valueA, objName + (objName == "" ? "" : ".") + objectType.Name);
        }
    }
}
