member this.Version : Version with get, set

Public Property Version As Version

Wartość właściwości

Version

Obiekt reprezentujący główne, pomocnicze, kompilacje i numery poprawek zestawu.

Przykłady

Ta sekcja zawiera dwa przykłady. W pierwszym przykładzie pokazano, jak pobrać wersję aktualnie wykonywanego zestawu. W drugim przykładzie pokazano, jak za pomocą Version właściwości określić wersję zestawu podczas emitowania zestawu dynamicznego.

Przykład 1

Poniższy przykład pobiera i wyświetla numery wersji aktualnie wykonywanego zestawu i zestawu zawierającego klasę String .

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

Przykład 2

Poniższy przykład emituje zestaw dynamiczny i zapisuje go w bieżącym katalogu. Po utworzeniu Version zestawu właściwość służy do określania informacji o wersji zestawu.

Uwagi

Wszystkie składniki wersji muszą być liczbami całkowitymi większymi lub równymi zero. Metadane ograniczają składniki główne, pomocnicze, kompilacji i poprawek dla zestawu do maksymalnej UInt16.MaxValue wartości – 1. Jeśli składnik przekroczy tę wartość, nie zostanie zgłoszony żaden błąd; jednak w zestawie dynamicznym ten składnik jest zerowy.
