通过

HttpCapabilitiesBase.Version 属性

  • 参考

定义

命名空间:
System.Web.Configuration
程序集:
System.Web.dll

以字符串形式获取浏览器的完整版本号（整数和小数）。

public:
 property System::String ^ Version { System::String ^ get(); };
public string Version { get; }
member this.Version : string
Public ReadOnly Property Version As String

属性值

String

浏览器的完整版本号（字符串形式）。

示例

下面的代码示例演示如何确定 Version 浏览器。 属性 MajorVersion 和 MinorVersion 属性是串联的，结果用于确定浏览器版本是否大于 5.01。

        System.Web.HttpBrowserCapabilities myBrowserCaps = Request.Browser;

注解

该 Version 属性返回一个字符串。 在某些情况下，该 Version 属性可能包含字母字符，就像是 Beta 版本（如“7.0b”）的浏览器或客户端设备的情况一样。 若要正确获取版本作为可用于数值比较的数据类型，请 MajorVersion 连接和 MinorVersion 属性值。
