I have following two classes:

C#

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; }      
    }

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

C#

ApplicantInfo appObj= new ApplicantInfo();

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

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

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 .

Try out below code :

C#

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();
}

Solution 1

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

I know that way..But my requirement is to get property names from the ApplicantInfo object without a separate loop..

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.

There isn't a way - there is no standard method which returns a heiracrhical structure of all properties.
You need a loop of some form, either direct (for, foreach...) or indirect via Linq
