Reference3.MajorVersion 属性
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。
