使用使用Server.Mappath（）在ASP.NET MVC中静态字段内 [英] Using Server.MapPath() inside a static field in ASP.NET MVC

问题描述

我建设我使用Lucene.Net搜索查询，其中一个ASP.NET MVC的网站。我asked这里如何正确结构Lucene.Net使用在ASP.NET MVC应用程序，被告知最好的方法是申报我的的IndexWriter 作为一个问题公共静态，因此，它可被重新使用。

I'm building an ASP.NET MVC site where I'm using Lucene.Net for search queries. I asked a question here about how to properly structure Lucene.Net usage in an ASP.NET MVC application and was told that the best method is to declare the my IndexWriter as public static, so that it can be re-used.

下面是一些code那是在我SearchController的顶部：

Here is some code that is at the top of my SearchController:

public static string IndexLocation = Server.MapPath("~/lucene");
public static Lucene.Net.Analysis.Standard.StandardAnalyzer analyzer = new Lucene.Net.Analysis.Standard.StandardAnalyzer();
public static IndexWriter writer = new IndexWriter(IndexLocation,analyzer);

由于作家是静态的， IndexLocation 也必须是静态的。因此，编译器是给我下面的错误为使用Server.Mappath（）：

As writer is static, IndexLocation must also be static. Thus, the compiler is giving me the following error for Server.MapPath():

的对象引用是所必需的非静态字段，方法或属性System.Web.Mvc.Controller.Server.get'

An object reference is required for the non-static field, method, or property 'System.Web.Mvc.Controller.Server.get'

有使用使用Server.Mappath（），或从一个静态字段类似的一种方式？如何解决这个问题？

Is there a way of using Server.MapPath() or something similar from a static field? How can I fix this error?

的先谢谢了。的

推荐答案

尝试<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.hosting.hostingenvironment.mappath.aspx\"><$c$c>HostingEnvironment.MapPath,这是静态。

请参阅确认这太问题的 HostingEnvironment.MapPath 返回相同的值使用Server.Mappath ：<一href=\"http://stackoverflow.com/questions/944219/what-is-the-difference-between-server-mappath-and-hostingenvironment-mappath\">What是使用Server.Mappath之间的差异，HostingEnvironment.MapPath？

See this SO question for confirmation that HostingEnvironment.MapPath returns the same value as Server.MapPath: What is the difference between Server.MapPath and HostingEnvironment.MapPath?
