How to get Class Name given its Property

Question

Is it possible to get the class name given the name of its property. If it is then how? Anyone can help me.

Answer 1

I don't think it is directly possible. You will have to search all the classes via reflection and you will have to look for that particular property in each class

Answer 2

If you have a PropertyInfo then you could use the DeclaringType property. If you only have some string you cannot get much from it. You will have to first get the property but to get the property you first need to get the declaring class, so you already know the declaring class.

Here is an example for mscorlib.dll. It finds all classes which have property named "Capacity".

Assembly asm = Assembly.Load("mscorlib.dll");
foreach (Type type in asm.GetTypes())
{
    foreach (MemberInfo mem in type.GetMembers())
    {
        if ((mem.MemberType == MemberTypes.Property) && (mem.Name == "Capacity"))
            Console.WriteLine(type);
    }
}

Or, using LINQ:

var asm = Assembly.Load("mscorlib.dll");
foreach (var type in from type in asm.GetTypes()
                     from mem in type.GetMembers()
                     where (mem.MemberType == MemberTypes.Property) &&
                        (mem.Name == "Capacity")
                     select type)
    Console.WriteLine(type);

Here is the output:

System.Collections.ArrayList+FixedSizeArrayList
System.Collections.ArrayList+ReadOnlyArrayList
