Procedura: reperire informazioni su tipo e membro da un assembly

Nello spazio dei nomi System.Reflection sono disponibili numerosi metodi per il recupero di informazioni da un assembly. In questa sezione viene illustrato uno di tali metodi. Per ulteriori informazioni, vedere Cenni preliminari sulla reflection.

L'esempio seguente consente di ottenere informazioni relative al tipo e al membro da un assembly.

Esempio

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();
}
