Load image from resources

I want to load the image like this:

void info(string channel)
{
    //Something like that
    channelPic.Image = Properties.Resources.+channel
}

Because I don't want to do

void info(string channel)
{
    switch(channel)
    {
        case "chan1":
            channelPic.Image = Properties.Resources.chan1;
            break;
        case "chan2":
            channelPic.Image = Properties.Resources.chan2;
            break;
    }
}

Is something like this possible?

ResourceManager will work if your image is in a resource file. If it is just a file in your project (let's say the root) you can get it using something like this:

System.Reflection.Assembly assembly = System.Reflection.Assembly.GetExecutingAssembly();
System.IO.Stream file = assembly .GetManifestResourceStream("AssemblyName." + channel);
this.pictureBox1.Image = Image.FromStream(file);

Or if you're in WPF:

private ImageSource GetImage(string channel)
{
    StreamResourceInfo sri = Application.GetResourceStream(new Uri("/TestApp;component/" + 
        channel, UriKind.Relative));
    BitmapImage bmp = new BitmapImage();
    bmp.BeginInit();
    bmp.StreamSource = sri.Stream;
    bmp.EndInit();
    return bmp;
}

You can add an image resource in the project then (right click on the project and choose the Properties item) access that in this way:

this.picturebox.image = projectname.properties.resources.imagename;

    this.toolStrip1 = new System.Windows.Forms.ToolStrip();
    this.toolStrip1.Location = new System.Drawing.Point(0, 0);
    this.toolStrip1.Name = "toolStrip1";
    this.toolStrip1.Size = new System.Drawing.Size(444, 25);
    this.toolStrip1.TabIndex = 0;
    this.toolStrip1.Text = "toolStrip1";
    object O = global::WindowsFormsApplication1.Properties.Resources.ResourceManager.GetObject("best_robust_ghost");

    ToolStripButton btn = new ToolStripButton("m1");
    btn.DisplayStyle = ToolStripItemDisplayStyle.Image;
    btn.Image = (Image)O;
    this.toolStrip1.Items.Add(btn);

    this.Controls.Add(this.toolStrip1);

Try this for WPF

StreamResourceInfo sri = Application.GetResourceStream(new Uri("pack://application:,,,/WpfGifImage001;Component/Images/Progess_Green.gif"));
picBox1.Image = System.Drawing.Image.FromStream(sri.Stream);

You can always use System.Resources.ResourceManager which returns the cached ResourceManager used by this class. Since chan1 and chan2 represent two different images, you may use System.Resources.ResourceManager.GetObject(string name) which returns an object matching your input with the project resources

Example

object O = Resources.ResourceManager.GetObject("chan1"); //Return an object from the image chan1.png in the project
channelPic.Image = (Image)O; //Set the Image property of channelPic to the returned object as Image

Notice: Resources.ResourceManager.GetObject(string name) may return null if the string specified was not found in the project resources.

Thanks,
I hope you find this helpful :)

You can do this using the ResourceManager:

public bool info(string channel)
{
   object o = Properties.Resources.ResourceManager.GetObject(channel);
   if (o is Image)
   {
       channelPic.Image = o as Image;
       return true;
   }
   return false;
}
