AssemblyName.Version 属性
定义
重要
一些信息与预发行产品相关,相应产品在发行之前可能会进行重大修改。 对于此处提供的信息,Microsoft 不作任何明示或暗示的担保。
获取或设置程序集的主版本号、次版本号、内部版本号和修订号。
public:
property Version ^ Version { Version ^ get(); void set(Version ^ value); };
public Version Version { get; set; }
public Version? Version { get; set; }
member this.Version : Version with get, set
Public Property Version As Version
属性值
一个对象,表示程序集的主版本号、次版本号、内部版本号和修订号。
示例
本部分包含两个示例。 第一个示例演示如何检索当前正在执行的程序集的版本。 第二个示例演示如何在发出动态程序集时使用 Version 属性指定程序集版本。
示例 1
以下示例检索并显示当前正在执行的程序集和包含 类的程序集的 String 版本号。
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
示例 2
以下示例发出一个动态程序集,并将其保存到当前目录。 创建程序集时, Version 属性用于指定程序集的版本信息。

注解
版本的所有组件必须是大于或等于零的整数。 元数据将程序集的主组件、次要组件、生成组件和修订组件限制为最大值 UInt16.MaxValue -1。 如果组件超过此值,则不会引发错误;但是,在动态程序集中,该组件为零。
