Load image from resources
Solution 1
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 :)
Solution 2
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;
}
Solution 3
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);
Solution 4
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;
}

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?
