浏览器检测

Question

我需要将IE和FF浏览器与其他浏览器分开

这是一个伪代码：

If (CurrentBrowser == IE(6+) or FF(2+) )
{
...
}
else 
{
...
}

在protected void Page_Load()事件中（如此）

if ((Request.Browser.Type == "IE") || (Request.Browser.Type == "FF"))
{
    WebMsgBox.Show("1111");
}

没有效果： - /什么是IE和FF类型？

Answer 1

if (Request.Browser.Type.Contains("Firefox")) // replace with your check
{
    ...
} 
else if (Request.Browser.Type.ToUpper().Contains("IE")) // replace with your check
{
    if (Request.Browser.MajorVersion  < 7)
    { 
        DoSomething(); 
    }
    ...
}
else { }

以下是一种可以请求有关所使用浏览器的信息的方法，您可以使用它来执行if语句

System.Web.HttpBrowserCapabilities browser = Request.Browser;
    string s = "Browser Capabilities\n"
        + "Type = "                    + browser.Type + "\n"
        + "Name = "                    + browser.Browser + "\n"
        + "Version = "                 + browser.Version + "\n"
        + "Major Version = "           + browser.MajorVersion + "\n"
        + "Minor Version = "           + browser.MinorVersion + "\n"
        + "Platform = "                + browser.Platform + "\n"
        + "Is Beta = "                 + browser.Beta + "\n"
        + "Is Crawler = "              + browser.Crawler + "\n"
        + "Is AOL = "                  + browser.AOL + "\n"
        + "Is Win16 = "                + browser.Win16 + "\n"
        + "Is Win32 = "                + browser.Win32 + "\n"
        + "Supports Frames = "         + browser.Frames + "\n"
        + "Supports Tables = "         + browser.Tables + "\n"
        + "Supports Cookies = "        + browser.Cookies + "\n"
        + "Supports VBScript = "       + browser.VBScript + "\n"
        + "Supports JavaScript = "     + 
            browser.EcmaScriptVersion.ToString() + "\n"
        + "Supports Java Applets = "   + browser.JavaApplets + "\n"
        + "Supports ActiveX Controls = " + browser.ActiveXControls 
              + "\n";

  <span class="fa fa-search"></span>
  <input placeholder="Search term" id="search" class="keyword">
</div>

Answer 4

    private void BindDataBInfo()
    {
        System.Web.HttpBrowserCapabilities browser = Request.Browser;
        Literal1.Text = "<table border=\"1\" cellspacing=\"3\" cellpadding=\"2\">";
        foreach (string key in browser.Capabilities.Keys)
        {
            Literal1.Text += "<tr><td>" + key + "</td><td>" + browser[key] + "</tr>";
        }
        Literal1.Text += "</table>";
        browser = null;
    }

Answer 5

我不建议使用JS手动浏览特定于浏览器的内容。使用像“prototype”或“jquery”这样的javascript库，它将透明地处理所有特定问题。

或者如果你真的必须使用这些库来确定浏览器类型。

另见Browser & version in prototype library?

为了浏览器兼容性，您可以使用此代码。此方法返回浏览器名称和版本：

private string GetBrowserNameWithVersion
{
    var userAgent = Request.UserAgent;
    var browserWithVersion = "";
    if (userAgent.IndexOf("Edge") > -1)
    {
        //Edge
        browserWithVersion = "Edge Browser Version : " + userAgent.Split(new string[] { "Edge/" }, StringSplitOptions.None)[1].Split('.')[0];
    }
    else if (userAgent.IndexOf("Chrome") > -1)
    {
        //Chrome
        browserWithVersion = "Chrome Browser Version : " + userAgent.Split(new string[] { "Chrome/" }, StringSplitOptions.None)[1].Split('.')[0];
    }
    else if (userAgent.IndexOf("Safari") > -1)
    {
        //Safari
        browserWithVersion = "Safari Browser Version : " + userAgent.Split(new string[] { "Safari/" }, StringSplitOptions.None)[1].Split('.')[0];
    }
    else if (userAgent.IndexOf("Firefox") > -1)
    {
        //Firefox
        browserWithVersion = "Firefox Browser Version : " + userAgent.Split(new string[] { "Firefox/" }, StringSplitOptions.None)[1].Split('.')[0];
    }
    else if (userAgent.IndexOf("rv") > -1)
    {
            //IE11
        browserWithVersion = "Internet Explorer Browser Version : " + userAgent.Split(new string[] { "rv:" }, StringSplitOptions.None)[1].Split('.')[0];
    }
    else if (userAgent.IndexOf("MSIE") > -1)
    {
        //IE6-10
        browserWithVersion = "Internet Explorer Browser  Version : " + userAgent.Split(new string[] { "MSIE" }, StringSplitOptions.None)[1].Split('.')[0];
    }
    else if (userAgent.IndexOf("Other") > -1)
    {
        //Other
        browserWithVersion = "Other Browser Version : " + userAgent.Split(new string[] { "Other" }, StringSplitOptions.None)[1].Split('.')[0];
    }

    return browserWithVersion;
}

Answer 7

我尝试并找到了相同的解决方案

        public static string GetBrowserDetails()
        {
          string  BrowserDetails = HttpContext.Current.Request.Browser.Browser + " - " + HttpContext.Current.Request.Browser.Version + ";  Operating System : " + HttpContext.Current.Request.Browser.Platform;
          return BrowserDetails;
        }

OUTPUT : 
Chrome - 88.0; Operating System : WinNT
