Get MethodInfo and MemberInfo

<source lang="csharp"> using System; using System.Reflection; public class Apple {

   public int nSeeds;
   public void Ripen() {
   }

} public class TypeOfApp {

   static void Main(string[] args) {
       Type t = typeof(Apple);
       string className = t.ToString();
       Console.WriteLine(className);
       Console.WriteLine(className);
       MethodInfo[] methods = t.GetMethods();
       foreach (MethodInfo method in methods) {
           Console.WriteLine(method.ToString());
       }
       Console.WriteLine(className);
       MemberInfo[] allMembers = t.GetMembers();
       foreach (MemberInfo member in allMembers) {
           Console.WriteLine(member.ToString());
       }
   }

}

Get variable base type and public numbers

<source lang="csharp"> using System; using System.Text; using System.Windows.Forms; using System.Reflection; class MainClass {

   static void Main() {
       Type t = typeof(double);
       Console.WriteLine("Type Name:  " + t.Name);
       Console.WriteLine("Full Name:  " + t.FullName);
       Console.WriteLine("Namespace:  " + t.Namespace);
       Type tBase = t.BaseType;
       if (tBase != null)
           Console.WriteLine("Base Type:" + tBase.Name);
       Type tUnderlyingSystem = t.UnderlyingSystemType;
       if (tUnderlyingSystem != null)
           Console.WriteLine("UnderlyingSystem Type:" + tUnderlyingSystem.Name);
       Console.WriteLine("\nPUBLIC MEMBERS:");
       MemberInfo[] Members = t.GetMembers();
       foreach (MemberInfo NextMember in Members) {
           Console.WriteLine(NextMember.DeclaringType + " " + NextMember.MemberType + " " + NextMember.Name);
       }
   }
