PathHelper

PathHelper class provides methods for combine and format ContentDirectory paths.

Configure()

Configure PathOptions in composition root of your application and then use Format() and Combine() methods.

PathOptions properties:

Property name	Property type	Description

    options.Template = (directory) => $"|{directory}Directory|";
    options.Directories[ContentDirectory.Base] = "D:\\WebApp";
    options.Directories[ContentDirectory.Data] = "D:\\WebApp\\App_Data";
});

Combine()

After configuring PathOptions you can simply combine ContentDirectory absolute path and relative path into a common path.

string path = PathHelper.Combine(ContentDirectory.Data, "readme.txt"); // Returns "D:\\WebApp\\App_Data\\readme.txt".

Format()

After configuring PathOptions you can simply replace content directory templates from path to content directory absolute paths.

var path = "|DataDirectory|\\foo\\bar\\baz.txt";
PathHelper.Configure(options =>
{
    options.Template = (directory) => $"|{directory}Directory|";
    options.Directories[ContentDirectory.Base] = "D:\\WebApp";
    options.Directories[ContentDirectory.Data] = "D:\\WebApp\\App_Data";
});

var result = PathHelper.Format(path, ContentDirectory.Data); // Returns "D:\\WebApp\\App_Data\\foo\\bar\\baz.txt".
