Question

I have a WebSite project – ASPX, 4.0. In it I have a folder like:

bin\Xslt\Template.xslt

I want to load this file in my class library. In web.config is:

 <configuration>
    <appSettings>
        <add key="Filepath" value=".\Xslt\Template.xslt" />
    </appSettings>
 </configuration>

But, my class library can’t find it:

 mTransform = new XslCompiledTransform();
 mTransform.Load(ConfigurationManager.AppSettings["Filepath"]);

throws: Could not find a part of the path 'C:\Xslt\Template.xslt'.
I know there’s a catch here, but I can’t remember the proper way…

How to reference a file in an aspx \bin\ folder correctly?

Answer 1

I found the way (since it’s in an assembly and I didn’t want to add dependency on System.Web):

string codeBase = Path.GetDirectoryName(Assembly.GetExecutingAssembly().CodeBase);
string filepathRelative = ConfigurationManager.AppSettings["Filepath"];

string fullFilepath = Path.Combine(codeBase, filepathRelative);

Thanks

edit: The System.AppDomain.CurrentDomain.BaseDirectory also does the trick…
