如何将引号字符作为路由参数?获取“路径中的非法字符”消息

我有一个搜索框存在于所有页面上。用户可以输入文本,然后单击“搜索”,结果显示在搜索页面上。

http://localhost:2010/search/my%20search%20term

这很管用。但如果我在字符串周围加引号,

http://localhost:2010/search/%22my%20search%20term%22

具有以下堆栈跟踪:

[ArgumentException: Illegal characters in path.]
   System.IO.Path.CheckInvalidPathChars(String path) +7493413
   System.IO.Path.Combine(String path1, String path2) +40
   System.Web.Configuration.UserMapPath.GetPhysicalPathForPath(String path, VirtualDirectoryMapping mapping) +114
   System.Web.Configuration.UserMapPath.GetPathConfigFilename(String siteID, VirtualPath path, String& directory, String& baseName) +72
   System.Web.Configuration.UserMapPath.MapPath(String siteID, VirtualPath path) +30
   System.Web.Configuration.UserMapPath.MapPath(String siteID, String path) +31
   System.Web.Hosting.HostingEnvironment.MapPathActual(VirtualPath virtualPath, Boolean permitNull) +297
   System.Web.Hosting.HostingEnvironment.MapPathInternal(VirtualPath virtualPath, Boolean permitNull) +51
   System.Web.CachedPathData.GetConfigPathData(String configPath) +341
   System.Web.CachedPathData.GetVirtualPathData(VirtualPath virtualPath, Boolean permitPathsOutsideApp) +110
   System.Web.HttpContext.GetFilePathData() +36
   System.Web.HttpContext.GetConfigurationPathData() +26
   System.Web.Configuration.RuntimeConfig.GetConfig(HttpContext context) +43
   System.Web.Configuration.CustomErrorsSection.GetSettings(HttpContext context, Boolean canThrow) +41
   System.Web.HttpResponse.ReportRuntimeError(Exception e, Boolean canThrow, Boolean localExecute) +101
   System.Web.HttpRuntime.FinishRequest(HttpWorkerRequest wr, HttpContext context, Exception e) +383

我不知道这里怎么了。。我需要以某种方式对输入进行编码吗?我需要在路由中指定不同的内容吗?
