Read a string stored in a resource file (resx) with dynamic file name

In my C# application I need to create a .resx file of strings customized for every customer.

What I want to do is avoid recompiling the entire project every time I have to provide my application to my customer, so I need to dynamic access to this string. So, how can I access (during the app execution) to a resx file if I kwow the file name only on the execution time?

Since now I write something similar:

Properties.Resources.MyString1

where Resource is my Resource.resx file. But I need something like this:

GetStringFromDynamicResourceFile("MyFile.resx", "MyString1");

Is it possible?

Thanks Mark

Use LINQ to SQL instead of referencing System.Windows.Forms.ResXResourceReader class in your project.

public string GetStringFromDynamicResourceFile(string resxFileName, string resource)
{
    return XDocument
                .Load(resxFileName)
                .Descendants()
                .FirstOrDefault(_ => _.Attributes().Any(a => a.Value == resource))?
                .Value;
}

And use it:

GetStringFromDynamicResourceFile("MyFile.resx", "MyString1");

You could put the needed resources into a separate DLL (one for each customer), then extract the resources dynamically using Reflection:

Assembly ass = Assembly.LoadFromFile("customer1.dll");
string s = ass.GetManifestResource("string1");

I may have the syntax wrong - it's early. One potential caveat here: accessing a DLL through Reflection will lock the DLL file for a length of time, which may block you from updating or replacing the DLL on the client's machine.

Of course it is possible. You need to read about ResouceSet class in msdn. And if you want to load .resx files directly, you can use ResxResourceSet.

Will something like this help in your case?

Dictionary<string, string> resourceMap = new Dictionary<string, string>();

public static void Func(string fileName)
{
    ResXResourceReader rsxr = new ResXResourceReader(fileName);        
    foreach (DictionaryEntry d in rsxr)
    {
        resourceMap.Add(d.Key.ToString(),d.Value.ToString());           
    }        
    rsxr.Close();
}

public string GetResource(string resourceId)
{
    return resourceMap[resourceId];
}
