调用ASP.NET app_code文件夹中的移动检测类方法

本文关键字:移动 检测 类方法 文件夹 code ASP NET app 调用 | 更新日期: 2023-09-27 17:56:40

摘要

我在app_code文件夹中的C#类文件中有一个ASP.NET 3.5网站和一个移动检测方法。我想调用这个方法来设置cookie,然后切换我的主页文件(如果是移动设备(。

我使用了一种方法,我从这篇文章的评论部分得到:http://www.codeproject.com/Articles/34422/Detecting-a-mobile-browser-in-ASP-NET

这似乎比使用51度检测方法更简单,因为我并不真正需要高级别的检测,我也不想将它们发送到不同的URL,而只是切换到不同的母版页,而且NuGet包不适用于ASP.NET 3.5。

我目前遇到的问题是调用该方法。

这是代码

我的使命(

现在我在页面上做,但我想我会在会话开始时在global.asax中做这件事吗?

sectionTitle.InnerHtml = fooBar.ean().ToString(); // test works
sectionTitle.InnerHtml = HttpRequestExt.IsMobileClient.ToString(); // compile error

编译错误:

CS0119:"SWIC.HttpRequestExt.IsMobileClient(System.Web.HttpRequest,System.Web.HttpRequest("是一个"方法",在给定的上下文中无效

我是否必须以某种方式将其转换为当前实例?我应该一起做不同的事情吗?

调用ASP.NET app_code文件夹中的移动检测类方法

您正试图调用一个类似于属性的方法。方法需要括号:

HttpRequestExt.IsMobileClient().ToString()
                             ^^

您还必须在当前请求中调用它,而不仅仅是静态调用,因为它是一个扩展方法(需要一个参数(。例如:

sectionTitle.InnerHtml = Page.Request.IsMobileClient(Page.Response).ToString();
