You can use Request.Browser to identify the browser info. These MSDN 1& 2article gives more info abt this.
您可以使用 Request.Browser 来识别浏览器信息。这些 MSDN 1& 2文章提供了更多信息。
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";

You may also want to look at: Request.ServerVariables.
您可能还想查看：Request.ServerVariables。
I have used:
我用过了：
string UserAgent = Request.ServerVariables["HTTP_USER_AGENT"];
Response.Write("User: " + UserAgent);
if(UserAgent.Contains("MSIE")) {
//do something
}
to show me what browser is being used. This can give you a response for IE similar to:
向我展示正在使用的浏览器。这可以为您提供类似于以下内容的 IE 响应：
User: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; Trident/4.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.5.21022; Tablet PC 2.0; .NET CLR 3.5.30729; .NET CLR 3.0.30729; .NET CLR 1.1.4322)
Depending on your version of IE or other browser. Firefox gives me:
取决于您的 IE 或其他浏览器的版本。Firefox 给了我：
User: Mozilla/5.0 (Windows NT 6.0; rv:11.0) Gecko/20100101 Firefox/11.0
It is important to note:I would use the ServerVariables over the Browser Capabilities because using BrowserCapabilities on Chrome will currently return "Desktop" which seems to be the same for Safari when I check it on a mac.
重要的是要注意：我会在浏览器功能上使用 ServerVariables，因为在 Chrome 上使用 BrowserCapabilities 当前将返回“桌面”，当我在 mac 上检查它时，它似乎与 Safari 相同。

This should list all browser capabilities...
这应该列出所有浏览器功能...
System.Web.HttpBrowserCapabilities browser = Request.Browser;
IDictionaryEnumerator enumerator = browser.Capabilities.GetEnumerator();
while (enumerator.MoveNext())
{
string key = (string)enumerator.Key.ToString();
object value = enumerator.Value;
Response.Write(String.Format("Key = {0}, Value = {1}", key, value));
}

Since Requestis a property of the page class, the above code gave me the error Request does not existand I used the following code to get the browser type
由于Request是页面类的一个属性，上面的代码给了我错误请求不存在，我用下面的代码来获取浏览器类型
private string GetBrowserType()
{
string browserType = string.Empty;
if (HttpContext.Current != null)
{
var request = HttpContext.Current.Request;
browserType = request.Browser.Type;
}
return browserType;
}
It gave me Chrome64with Chrome and InternetExplorer11with IE
它给了我Chrome64Chrome 和InternetExplorer11IE
