Default.aspx.cs

    </form>
</body>
</html>


Default.aspx.cs
using System;

namespace WebApplication2
{
    public partial class Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }
        protected void Button1_Click(object sender, EventArgs e)
        {
            System.Web.HttpBrowserCapabilities browser = Request.Browser;
            string s = "Browser Capabilities<br /><br />"
                + "Type = " + browser.Type + "<br />"
                + "Name = " + browser.Browser + "<br />"
                + "Version = " + browser.Version + "<br />"
                + "Major Version = " + browser.MajorVersion + "<br />"
                + "Minor Version = " + browser.MinorVersion + "<br />"
                + "Platform = " + browser.Platform + "<br />"
                + "Is Beta = " + browser.Beta + "<br />"
                + "Is Crawler = " + browser.Crawler + "<br />"
                + "Is AOL = " + browser.AOL + "<br />"
                + "Is Win16 = " + browser.Win16 + "<br />"
                + "Is Win32 = " + browser.Win32 + "<br />"
                + "Supports Frames = " + browser.Frames + "<br />"

                + "Supports VBScript = " + browser.VBScript + "<br />"
                + "Supports JavaScript = " +
                    browser.EcmaScriptVersion.ToString() + "<br />"
                + "Supports Java Applets = " + browser.JavaApplets + "<br />"
                + "Supports ActiveX Controls = " + browser.ActiveXControls
                      + "<br />";
            Label1.Text = s;
        }
    }
}

編譯有警告，先不理會

            // 警告  CS0618  'HttpCapabilitiesBase.JavaScript' 已經過時: 'The recommended alternative is the EcmaScriptVersion property. A Major version value greater than or equal to 1 implies JavaScript support. http://go.microsoft.com/fwlink/?linkid=14202'  Browser D:\CodeTemp\Browser\Browser\Default.aspx.cs 28  作用中
