How to: Get type and member information by using reflection

The System.Reflection namespace contains many methods for obtaining information about types and their members. This article demonstrates one of these methods, Type.GetMembers. For additional information, see Reflection overview.

Example

The following example obtains type and member information by using reflection:

using System;
using System.Reflection;

class Asminfo1
{
    public static void Main()
    {
        Console.WriteLine ("\nReflection.MemberInfo");

        // Get the Type and MemberInfo.
        // Insert the fully qualified class name inside the quotation marks in the
        // following statement.
        Type MyType = Type.GetType("System.IO.BinaryReader");
        MemberInfo[] Mymemberinfoarray = MyType.GetMembers(BindingFlags.Public |
            BindingFlags.NonPublic | BindingFlags.Static |
            BindingFlags.Instance | BindingFlags.DeclaredOnly);

        // Get and display the DeclaringType method.
        Console.Write($"\nThere are {Mymemberinfoarray.Length} documentable members in ");
        Console.Write($"{MyType.FullName}.");

        foreach (MemberInfo Mymemberinfo in Mymemberinfoarray)
        {
            Console.Write("\n" + Mymemberinfo.Name);
        }
    }
}

Imports System.Reflection

Class Asminfo1
    Public Shared Sub Main()
        Console.WriteLine("\nReflection.MemberInfo")

        ' Get the Type and MemberInfo.
        ' Insert the fully qualified class name inside the quotation marks in the
        ' following statement.
        Dim MyType As Type = Type.GetType("System.IO.BinaryReader")
        Dim Mymemberinfoarray() As MemberInfo = MyType.GetMembers(BindingFlags.Public Or
            BindingFlags.NonPublic Or BindingFlags.Static Or
            BindingFlags.Instance Or BindingFlags.DeclaredOnly)

        ' Get and display the DeclaringType method.
        Console.Write($"\nThere are {Mymemberinfoarray.Length} documentable members in ")
        Console.Write($"{MyType.FullName}.")

        For Each Mymemberinfo As MemberInfo in Mymemberinfoarray
            Console.Write("\n" + Mymemberinfo.Name)
        Next
    End Sub
End Class
