Version

物件,表示組件的主要、次要、組建和修訂編號。An object that represents the major, minor, build, and revision numbers of the assembly.

範例

本章節包含兩個範例。This section contains two examples. 第一個範例示範如何取得目前執行中元件的版本。The first example shows how to retrieve the version of the currently executing assembly. 第二個範例顯示如何使用 Version 屬性,在發出動態元件時指定元件版本。The second example shows how to use the Version property to specify the assembly version when you emit a dynamic assembly.

範例 1Example 1

下列範例會抓取並顯示目前正在執行之元件的版本號碼,以及包含類別的元件 StringThe following example retrieves and displays the version numbers of the currently executing assembly and the assembly that contains the String class.

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

範例 2Example 2

下列範例會發出動態元件,並將它儲存至目前的目錄。The following example emits a dynamic assembly and saves it to the current directory. 建立元件時, Version 會使用屬性來指定元件的版本資訊。When the assembly is created, the Version property is used to specify version information for the assembly.

備註

版本的所有元件都必須是大於或等於零的整數。All components of the version must be integers greater than or equal to zero. 中繼資料會將元件的主要、次要、組建和修訂元件限制為-1 的最大值 UInt16.MaxValueMetadata restricts the major, minor, build, and revision components for an assembly to a maximum value of UInt16.MaxValue - 1. 如果元件超過此值,就不會擲回任何錯誤;不過,在動態元件中,該元件為零。If a component exceeds this value, no error is thrown; however, in a dynamic assembly, that component is zero.
