Valore della proprietà

Version

Oggetto che rappresenta il numero principale, secondario, di build e di revisione dell'assembly.

Esempio

Questa sezione contiene due esempi. Nel primo esempio viene illustrato come recuperare la versione dell'assembly attualmente in esecuzione. Nel secondo esempio viene illustrato come utilizzare la Version proprietà per specificare la versione dell'assembly quando si genera un assembly dinamico.

Esempio 1

Nell'esempio seguente vengono recuperati e visualizzati i numeri di versione dell'assembly attualmente in esecuzione e dell'assembly che contiene la String classe .

using namespace System;
using namespace System::Reflection;

[assembly:AssemblyVersion("1.1.0.0")];

void main()
{
    Console::WriteLine("The version of the currently executing assembly is: {0}",
        Assembly::GetExecutingAssembly()->GetName()->Version);

    Console::WriteLine("The version of mscorlib.dll is: {0}",
        String::typeid->Assembly->GetName()->Version);
}

/* This example produces output similar to the following:

The version of the currently executing assembly is: 1.1.0.0
The version of mscorlib.dll is: 2.0.0.0
 */

using System;
using System.Reflection;

[assembly:AssemblyVersion("1.1.0.0")]

class Example
{
    static void Main()
    {
        Console.WriteLine("The version of the currently executing assembly is: {0}",
            typeof(Example).Assembly.GetName().Version);

        Console.WriteLine("The version of mscorlib.dll is: {0}",
            typeof(String).Assembly.GetName().Version);
    }
}

/* This example produces output similar to the following:

The version of the currently executing assembly is: 1.1.0.0
The version of mscorlib.dll is: 2.0.0.0
 */

Imports System.Reflection

<Assembly:AssemblyVersion("1.1.0.0")>

Class Example

    Shared Sub Main()
    
        Console.WriteLine("The version of the currently executing assembly is: {0} ", _
            GetType(Example).Assembly.GetName().Version)

        Console.WriteLine("The version of mscorlib.dll is: {0} ", _
            GetType(String).Assembly.GetName().Version)
    End Sub
End Class

' This example produces output similar to the following:
'
'The version of the currently executing assembly is: 1.1.0.0
'The version of mscorlib.dll is: 2.0.0.0

Esempio 2

L'esempio seguente genera un assembly dinamico e lo salva nella directory corrente. Quando viene creato l'assembly, la Version proprietà viene utilizzata per specificare le informazioni sulla versione per l'assembly.

Commenti

Tutti i componenti della versione devono essere numeri interi maggiori o uguali a zero. I metadati limitano i componenti principali, secondari, di compilazione e di revisione per un assembly a un valore massimo pari UInt16.MaxValue a - 1. Se un componente supera questo valore, non viene generato alcun errore; Tuttavia, in un assembly dinamico, tale componente è zero.
