Locate resources after Resources Compression and Encryption

Hi,

I'm trying to locate resources following checking 'Resources Compression and Encryption' (in SmartAssembly Professional 6.8.0.121) and while I can reach them by directly naming them, I'm unable to using LINQ to collect a sub-set - something I was able to do prior to using the feature.

Below is an example snippet that demonstrates the problem. 'btnReadResources_Click' returns the expected results, but 'btnFindResources_Click' does not. Is there a good way around this problem, where I can filter the available encrypted resources based on part of the namespace?.

Best regards

John

private void btnReadResources_Click(object sender, RoutedEventArgs e)
{
    var assembly = Assembly.GetExecutingAssembly();
    txtAOutput.Text = "";
    txtBOutput.Text = "";
            
    txtAOutput.Text = txtAOutput.Text + "\n" + GetResText(assembly, "TestEmbeddedResources.MyResFolder.A.FldrA1.TxtA1.txt");
    txtAOutput.Text = txtAOutput.Text + "\n" + GetResText(assembly, "TestEmbeddedResources.MyResFolder.A.FldrA2.TxtA2.txt");
    txtAOutput.Text = txtAOutput.Text + "\n" + "[Done]";

    txtBOutput.Text = txtBOutput.Text + "\n" + GetResText(assembly, "TestEmbeddedResources.MyResFolder.B.FldrB1.TxtB1.txt");
    txtBOutput.Text = txtBOutput.Text + "\n" + GetResText(assembly, "TestEmbeddedResources.MyResFolder.B.FldrB2.TxtB2.txt");
    txtBOutput.Text = txtBOutput.Text + "\n" + GetResText(assembly, "TestEmbeddedResources.MyResFolder.B.FldrB3.TxtB3.txt");
    txtBOutput.Text = txtBOutput.Text + "\n" + "[Done]";
}

       

private void btnFindResources_Click(object sender, RoutedEventArgs e)
{
    var assembly = Assembly.GetExecutingAssembly();
    txtAOutput.Text = "";
    txtBOutput.Text = "";


    var stdResNames = assembly.GetManifestResourceNames()
                        .Where(name => name.StartsWith("TestEmbeddedResources.MyResFolder.A."));

    foreach (var stdResName in stdResNames)
    {
        AddResString(txtAOutput, GetResText(assembly, stdResName));
    }
    AddResString(txtAOutput, "[Done]");



    var proResNames = assembly.GetManifestResourceNames()
                        .Where(name => name.StartsWith("TestEmbeddedResources.MyResFolder.B."));

    foreach (var proResName in proResNames)
    {
        AddResString(txtBOutput, GetResText(assembly, proResName));
    }
    AddResString(txtBOutput, "[Done]");
}

private string GetResText(Assembly assembly, string resName)
{
    string result;
    using (var stream = assembly.GetManifestResourceStream(resName))
    using (var reader = new StreamReader(stream))
    {
            result = reader.ReadToEnd();
    }
    return result;
}

private void AddResString(TextBox txtBx, string strRes)
{
    txtBx.Text = txtBx.Text + "\n" + strRes;
}

    Ok, so I'm going to answer my own question as I've now spotted that the docs for 'Resources Compression and Encryption' state that you can't use it with GetManifestResourceNames, which I am.

    Interestingly, if you just loop through the array returned by GetManifestResourceNames then you end up with a single name (a GUID) of the compressed and encrypted resource. Well I suppose I understand the process better now :)

    I guess, on reflection (small pun intended), I'm really after encryption but not compression, or at least the means to 'lookup' encrypted resources by name.

    Anyway, I hope that help anyone else looking at the feature.

    Best regards

    John
