C＃反射分配

Question

so I need some help with this. I tried searching SOF, but I had no luck.

Using reflection, I need to test .NET String class. I need to show class name, interfaces that, this class implements, the assembly where this class is found, namespace of this class, type that inherits, and basic informations. Is this class abstract, generic, sealed etc. I had been learning this for 20 days, now, and I had no luck, so I was learning attributes, reflection, and assemblies, and metadata assemblies, EDIT: My question is: How to write this properly, I tried like 1000x, and nothing, always some mistakes, always errors, I do not know how to start..

Answer 1

class Program
{
    static void Main()
    {
        TellMeAboutType(typeof(string));
    }
    static void TellMeAboutType(Type type)
    {
        Console.WriteLine("Name: " + type.Name);
        Console.WriteLine("Namespace: " + type.Namespace);
        Console.WriteLine("Assembly: " + type.Assembly.FullName);
        Console.WriteLine("AQN: " + type.AssemblyQualifiedName);
        Console.WriteLine("Abstract: " + type.IsAbstract);
        Console.WriteLine("Generic: " + type.IsGenericType);
        Console.WriteLine("Sealed: " + type.IsSealed);
        Console.WriteLine("Base Type: " + type.BaseType.FullName);
        foreach(var iType in type.GetInterfaces())
        {
            Console.WriteLine("Implements: " + iType.FullName);
        }
    }
}

I know Marc already answered, but I wanted to answer the short version of the question "How to start with reflection?"

Basically, you need a reference to the type. For that there are two methods: 1. In case you know the type (or it is a generic eg <T> ): typeof(MyType) or typeof(T) . 2. In case you have an object instance, then you need to get the type first, which is also simple: myObject.GetType()

In both cases, then you just use the properties of the Type object you got, like Marc shown.
