Reference3.MajorVersion 属性

项目
10/25/2012

获取引用的主版本号。

命名空间： VSLangProj80
程序集： VSLangProj80（在 VSLangProj80.dll 中）

语法

声明
ReadOnly Property MajorVersion As Integer

int MajorVersion { get; }

property int MajorVersion {
    int get ();
}

abstract MajorVersion : int

function get MajorVersion () : int

属性值

类型：System.Int32
一个整数，其值取决于引用类型。

引用类型	返回的值
程序集	引用的主版本号；0–9999。
COM	一个 Int 值。

备注

引用的版本由四个部分唯一标识，它们是：主版本、次版本、内部版本和修订版本。主版本和次版本部分是必需的。未定义内部版本时，修订版本部分是可选的。 COM 对象没有修订版本和内部版本部分。有关更多信息，请参见程序集版本控制。

示例

此示例向打开的 Visual Basic 或 Visual C# 项目添加程序集和 COM 引用，并显示它们的主版本号。若要将此示例作为外接程序运行，请参见如何：编译和运行自动化对象模型代码示例。

所添加的引用的默认路径为：对于 adodb.dll 为 <安装根目录>\Program Files\Microsoft.NET\Primary Interop Assemblies，对于 spcommon.dll 为 <安装根目录>\Program Files\Common Files\SpeechEngines\Microsoft。请将示例中的 <file path> 替换为这些文件路径或其他适当的文件路径。
