Question

I had a look at this previous question however this doesn’t seem to work for XNA 4 for a Windows Phone 7 project: XNA Framework Importers

I’ve been trying to use:

string line; 
using (StreamReader sr = new StreamReader("credits.txt"))
{
    while ((line = sr.ReadLine()) != null)
    {
         //reads line by line until eof        
         //do whatever you want with the text
    }
}

`

but this is throwing a System.MethodAccessException “Attempt to access the method failed: System.IO.StreamReader..ctor(System.String)”

Do I need to look at using IsolatedStorage for this instead?

Edit: Please note I am trying to load a pre-prepared file, not save settings for a running application. e.g. a text file containing credits that I will only read in at run time but need to be able to edit during design time.

Found it; I can do this without IsolatedStorage, just need to use an XML file structured as such:

<?xml version="1.0" encoding="utf-8" ?>
<XnaContent>
  <Asset Type="System.String">
    <credit>
      Firece Game Hunting

      Developer : Sebastian Gray

      Deer (CC) : Martin Pettitt
      

    </credit>
  </Asset>
</XnaContent>

and then load the XML file like this:

public string LoadFromFile()
{
    using (System.Xml.XmlReader reader = System.Xml.XmlReader.Create("XMLFile1.xml"))
    {
        reader.MoveToContent();
        reader.ReadToFollowing("credit");
        credits = reader.ReadInnerXml();
    }
    return credits;
}

The XML file can just be added to the the normal project (not the content project) and set the build action to ‘Content’ and the Copy to Output Directory to ‘Copy always’.
