How to check a class contains property of another class in c#?

I have a class like -

class AClass {
  public int P1 { get; set; }
  public string P2 { get; set; }
  public string P3 { get; set; }
}

Another class like -

class BClass {
  public int P1 { get; set; }
  public string P2{ get; set; }
}

I want to check check if class AClass contains(should match both name and type) properties of BClass or not. How can do that?

You can use reflection on the types and find the properties with the same name & type

var commonProperties = 
    typeof(AClass).GetProperties().Join(typeof(BClass).GetProperties(),                
    prop => new {prop.PropertyType, prop.Name},
    prop => new {prop.PropertyType, prop.Name},
            (propA, propB)=>propA.Name);

Do note however, that code snippet only checks for Name & Type. There are dozens of other things that could be different, like availability of get, set, attributes,..

a way of testing this with reflection could be this:

var propertiesOfA = typeof(AClass).GetProperties();
var propertiesOfB = typeof(BClass).GetProperties();

var commonProperties = propertiesOfB.Where(
    b => propertiesOfA.Any(
        a => 
            b.Name == a.Name 
            && b.PropertyType == a.PropertyType
        )
    ).ToArray();

You can check the properties of the two classes and select these names.

   var duplicates = typeof(AClass).GetProperties().Where(a => typeof(BClass).GetProperties().Any(b => b.Name == a.Name && b.PropertyType == a.PropertyType)).Select(x => x.Name);

You could solve tis using reflection :

PropertyInfo[] myPropertyInfo;
myPropertyInfo = Type.GetType("System.Type").GetProperties();
Console.WriteLine("Properties of System.Type are:");
for (int i = 0; i < myPropertyInfo.Length; i++)
{
    Console.WriteLine(myPropertyInfo[i].ToString());
}
