在C＃中实现文件访问的最佳方式

Scenario - I need to access an HTML template to generate a e-mail from my Business Logic Layer. It is a class library contains a sub folder that contains the file. When I tried the following code in a unit test:

场景 - 我需要访问HTML模板以从我的业务逻辑层生成电子邮件。它是一个类库,包含一个包含该文件的子文件夹。当我在单元测试中尝试以下代码时:

string FilePath = string.Format(@"{0}\templates\MyFile.htm", Environment.CurrentDirectory);
string FilePath1 = string.Format(@"{0}\templates\MyFile.htm", System.AppDomain.CurrentDomain.BaseDirectory);

It was using the C:\WINNT\system32\ or the ASP.NET Temporary Folder directory.

它使用的是C:\ WINNT \ system32 \或ASP.NET临时文件夹目录。

What is the best to access this file without having to use an app.config or web.config file?

在不使用app.config或web.config文件的情况下访问此文件的最佳方法是什么?

You're running this from an ASP.Net app right? Use Server.MapPath() instead.

你是从ASP.Net应用程序运行的吗?请改用Server.MapPath()。

Also take a look at System.IO.Path.Combine() for concatenating paths.

另请参阅System.IO.Path.Combine()以连接路径。

[Edit] Since you can't use System.Web, try this:

[编辑]由于你不能使用System.Web,试试这个:

System.Reflection.Assembly.GetExecutingAssembly().Location

Or GetEntryAssembly().

I belive you are looking for

我相信你在寻找

System.IO.Path.GetDirectoryName(Application.ExecutablePath);

I got this working on my site! I haven't been working on just this for the last 2 years!!!

我在我的网站上工作了!在过去的两年里,我一直没有做过这个!

I added this inside my system.serviceModel block of the web.config. It seems to make all the paths relative to where your service is installed.

我在web.config的system.serviceModel块中添加了这个。它似乎使所有路径都相对于您的服务安装位置。

  <system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true">

better late than never?

迟到总比不到好?

Use

System.Web.HttpServerUtility.MapPath( "~/templates/myfile.htm" )
