Relative paths in an ASP.NET application code behind
提问by kmarks2
Being new to ASP.NET I'm unsure of the best solution to my problem. I have a line of code like:
作为 ASP.NET 的新手，我不确定我的问题的最佳解决方案。我有一行代码，如：
xDoc.Load("Templates/template1.cfg");
xDoc is an XmlDocument. In my project, at the top level there is a directory called Templates. When I run the project in debug mode, I get a DirectoryNotFoundException, and apparently it's looking for the Templates dir in C:\Program Files\Common Files\Microsoft Shared\DevServer\10.0\Templates.
xDoc 是一个XmlDocument. 在我的项目中，顶层有一个名为 Templates 的目录。当我在调试模式下运行项目时，我得到一个DirectoryNotFoundException，显然它正在C:\Program Files\Common Files\Microsoft Shared\DevServer\10.0\Templates.
How can correctly point to that directory without hardcoding it?
如何在没有硬编码的情况下正确指向该目录？

Server.MapPath- returns the path of the relative path; ~ensures the relative path is related to the application root
Server.MapPath- 返回相对路径的路径；~确保相对路径与应用程序根相关
xDoc.Load(Server.MapPath("~/Templates/template.cfg"));

xDoc.Load("~/Templates/template.cfg");
might work?
可能有用吗？

Use a tilde "~" in your path.
在您的路径中使用波浪号“~”。
xDoc.Load("~/Templates/template1.cfg");
The tilde represents the base directory for your application.
波浪号代表您的应用程序的基本目录。

I would probably use
我可能会用
xDoc.Load(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Templates", "Template.cfg"));
This makes your XML loading code independent of ASP.NET. If you were to reuse it in, say, a Windows Forms application, this would give a path relative to the directory containing the Windows Forms exectuable.
这使您的 XML 加载代码独立于 ASP.NET。如果您要在 Windows 窗体应用程序中重用它，这将给出一个相对于包含 Windows 窗体可执行文件的目录的路径。

Try:
尝试：
xDoc.Load(Server.MapPath("~/Templates/template1.cfg"));
