Get a TextReader from a Stream?

Question

I'm trying to read an embedded text file with System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(resource); but it gives me a Stream. The embedded resource is a text file so, how can I turn this Stream into a TextReader?

Solution 1

TextReader tr = new StreamReader(stream);

Solution 2

A StreamReader is a subclass of TextReader, so you will be able to do:

using(var stream = System.Reflection.Assembly.GetExecutingAssembly().
    GetManifestResourceStream(resource))
using(var reader = new StreamReader(stream))
{
    // Use reader.
}

Solution 3

You can read your resource file like this :

Assembly resourceAssembly = Assembly.LoadFrom(resourceFile.FullName);
string[] manifests = resourceAssembly.GetManifestResourceNames();

using (ResourceReader reader = new ResourceReader(
    resourceAssembly.GetManifestResourceStream(manifests[0])))
{
    foreach (IDictionaryEnumerator dict in reader)
    {
        string key = dict.Key as string;
        object val = dict.Value;
    }
}

Solution 4

You need to get a StreamReader from it (TextReader is an abstract base class of StreamReader and StringReader). Something like:

var stream = System.Reflection.Assembly.GetExecutingAssembly().
    GetManifestResourceStream(resource);
var reader = new StreamReader(stream);
var text = reader.ReadToEnd();

A foreach loop is better than an explicit enumerator.
