Using a resource file

NETMF & Gadgeteer
1

Hello,

I’d like to use a resource file and want to read values from it during runtime.

Now I got something like:


using System;
using System.Collections;
using System.Threading;
using System.Resources;
using System.Reflection;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using GHIElectronics.NETMF.FEZ;

namespace MFConsoleApplication1
{
    public class Program
    {   
        public static void Main()
        {
            ResourceManager rm = new ResourceManager("Resources", Assembly.GetExecutingAssembly());

         }
    }
}

I’d like to do something like:

Debug.print(rm.GetString("string1"));

But that won’t work…
Any suggestions?

Thanks,
Jeroen

There is an examples of how to loading the resource here:

Hope this help.

Hi Sam,

Thanks for your reply. I’ve also found that one, but I can only read it like:


Resources.GetString(Resources.StringResources.String1)

Where the string is fixed in the code.

But I want something like:


string sKey="string1";
Resources.GetString(Resources.StringResources(sKey))

Well, It works fine with me!

Here is the code:

using System;
using System.Threading;

using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;

using GHIElectronics.NETMF.FEZ;

namespace FEZ_Domino_Application1
{
    public class Program
    {
        public static void Main()
        {
            // Blink board LED

            bool ledState = false;

            OutputPort led = new OutputPort((Cpu.Pin)FEZ_Pin.Digital.LED, ledState);

            while (true)
            {
                // Sleep for 500 milliseconds
                Thread.Sleep(500);

                // toggle LED state
                ledState = !ledState;
                led.Write(ledState);

                Debug.Print(
                    Resources.GetString(Resources.StringResources.String1));

            }
        }

    }
}

Hi Sam,

That’s working for me as well, but is not what I want.
I Want to get a specific resource, which name is inside a string.
So not Resources.StringResources.String1
string key=“string1”;
But something like Resources.StringResources(key)

Hullie,

That is not how it works. Each resource is given an id which is a short number.

When you add a resource VS adds a value to an enumeration that makes easy for you to access the resource:

Open Resources.Designer.cs. You might find there something like this:

[System.SerializableAttribute()]
        internal enum StringResources : short
        {
            String2 = 1225,
            String1 = 1228,
        }

Visual Studio will add separate enumeration for each type of resource. But again the key is a short value.

Remember it is about “thinking small”. With limited resources it makes sense to use a short value for the key instead of a string.

May I ask why are you insisting on using strings for resource keys other than using what you have for free?

AFAICT, you have to cook that yourself, because we don’t have Enum.GetNames.
Basically, create a switch method that returns the Enum from a name and use the Enum.

private static Properties.Resources.StringResources GetByName(string name)
{
    switch (name.ToLower())
    {
        case "string1":
            return Properties.Resources.StringResources.String1;
        default:
            throw new InvalidOperationException("Invalid resource name");
    }
}

string s = Properties.Resources.GetString(GetByName("string1"));
Debug.Print(s);

Hi William,

Ok thanks!
That’s the way I’m doing it now.
I’ve to explicitly name all the keys which are in the resource file. :frowning:
But, it’s working :slight_smile:
