How to: Obtain Type and Member Information from an Assembly

The System.Reflection namespace contains many methods for obtaining information from an assembly. This section demonstrates one of these methods. For additional information, see Reflection Overview.

The following example obtains type and member information from an assembly.

Example

Imports System
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 {0} documentable members in ", Mymemberinfoarray.Length)
        Console.Write("{0}.", MyType.FullName)

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

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 {0} documentable members in ", Mymemberinfoarray.Length);
        Console.Write("{0}.", MyType.FullName);

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

using namespace System;
using namespace System::Reflection;

ref 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");
        array<MemberInfo^>^ Mymemberinfoarray = MyType->GetMembers(BindingFlags::Public |
            BindingFlags::NonPublic | BindingFlags::Static |
            BindingFlags::Instance | BindingFlags::DeclaredOnly);

        // Get and display the DeclaringType method.
        Console::Write("\nThere are {0} documentable members in ", Mymemberinfoarray->Length);
        Console::Write("{0}.", MyType->FullName);

        for each (MemberInfo^ Mymemberinfo in Mymemberinfoarray)
        {
            Console::Write("\n" + Mymemberinfo->Name);
        }
    }
};

int main()
{
    Asminfo1::Main();
}
