如何获取类的属性名称 [英] How to get property name of class

问题描述

我有以下两个课程：

I have following two classes:

public class ApplicantInfo
    {
        public Int32 StudentId { get; set; }
        public String StudentName { get; set; }
        public DateTime DateOfBirth { get; set; } 
        public String Phone { get; set; }
        public String Email { get; set; }
        public Byte[] Image { get; set; }
        public SchoolDetail SchoolDetailObj { get; set; }      
    }   

public class SchoolDetail 
    {
        public string SchoolName { get; set; }
        public string SchoolPhone { get; set; }
        public string SchoolFax { get; set; }
        public string SchoolEmail { get; set; }      
    }    

在ApplicantInfo类中，我放置了SchoolDetail类的对象。



i want获取这两个类的所有属性名称。所以我写下面的代码

In ApplicantInfo class i have placed the object of SchoolDetail class .

i want to get all property names of both these classes. So i write the following code

ApplicantInfo appObj= new ApplicantInfo();

 Type ApplicantInfo = appObj.GetType();
                    PropertyInfo[] properties = ApplicantInfo.GetProperties();

foreach (PropertyInfo property in properties)
                          {
                             var propName= property.Name.ToString()
                             }

获取财产ApplicantInfo的名称完美但不是SchoolDetail类的名称。它将SchoolDetailObj显示为属性。但我想获得SchoolDetail类的属性名称。请帮帮我。

It gets the property name of ApplicantInfo perfectly but not the propery names of SchoolDetail class. It shows SchoolDetailObj as the property. But i want to get the property names of SchoolDetail class . Please help me .

推荐答案

因为你使用的是ApplicantInfo类的对象。为SchoolDetail创建一个单独的对象，并在循环中迭代该属性Collection。

Because you are using the object of ApplicantInfo class. Create a separate object for the SchoolDetail and iterate that property Collection in loop.

SchoolDetailObj是ApplicantInfo类的一个属性，这意味着您正在正确地检索信息 - 但系统没有自动返回属性的属性 - 否则它将返回字符串的所有属性，字节数组，DateTime值等。



如果你想要属性的属性，你需要在该类上再次执行相同的代码作为一个单独的循环。

SchoolDetailObj is a property of the ApplicantInfo class, which means you are retrieving the info correctly - but the system doesn't automatically return the properties of properties - otherwise it would return all the properties of the string, the byte array, the DateTime value, and so on.

If you want the properties of a property, you need to execute the same code again on that class as a separate loop.

尝试下面的代码：

Try out below code :

var properties = ApplicantInfo.GetProperties().ToDictionary(x => x, x => x.GetType().GetProperties());
foreach (var item in properties)
{
    Console.WriteLine(item.Key);
    foreach (PropertyInfo property in item.Value)
    {
         Console.WriteLine(" propName = " + property.Name.ToString());
    }
    Console.WriteLine();
}
