Loading and accessing template variables inside text file

we have a bunch of text templates that are embedded resources in our visual studio solution.

I'm using a simple method like this to load them:

public string getTemplate()
var assembly = Assembly.GetExecutingAssembly();
var templateName = "ResearchRequestTemplate.txt";
string result;

using (Stream stream = assembly.GetManifestResourceStream(templateName))
using (StreamReader reader = new StreamReader(stream))
result = reader.ReadToEnd();
return result;

So I can load the file with the above method, but how do I replace the template variables inside the file with variables I've created in my code? Is that even possible? Maybe I'm going about this all wrong...


Hello { FellowDisplayName }

You have requested access to the { ResearchProjectTitle } Project.

Please submit all paperwork and badge ID to { ResourceManagerDisplayName }

You could use a series of string.Replace() statements.

Or you could modify the template and make use of string.Format:

Hello {0}

You have requested access to the {1} Project.

    Please submit all paperwork and badge ID to {2}

After you read in the template, insert the correct values:

return string.Format(
    result, fellowDisplayName, researchProjectTitle, resourceManagerDisplayName);

This could be a bit error prone if the template changes often, and someone's not being careful to make sure the numbering in the template matches the order of parameters being passed in.
