Load image to image box using C#

I am trying to load an image to picture box the below way worked with me.
image1.Image = Properties.Resources._0;
what it i want make the code reading from resources as variable name like the way below.
var imagename = _0;
image1.Image = Properties.Resources.imagename;
Thanks

Use the ResourceManager and pass it a string:
var imageName = "_0";
image1.Image = (Image)Properties.Resources.ResourceManager.GetObject(imageName);

load an image from resources in Visual C#, using a string?

If I have some resources, eg card1.png, card2.png, etc,
I want to them load them into a picBox, but only load the correct image
eg, something like
int cardNum = rn.Next(0,cardMax);
picCard.Image = Properties.Resources."card"+cardNum+".png";
Obviously that doesn't work, but how would I do what I am trying to do (load the correct resource after building the resource name into a string)

Instead of the generated properties in the Resources class use the ResourceManager directly:
string resName = $"card{cardNum}.png"; // Check the correct name in the .resx file. By using the wizards the extension is omitted, for example.
picCard.Image = (Image)Properties.Resources.ResourceManager.GetObject(resName);

Try using:
var rm = new System.Resources.ResourceManager(((System.Reflection.Assembly)System.Reflection.Assembly.GetExecutingAssembly()).GetName().Name + ".Properties.Resources", ((System.Reflection.Assembly)System.Reflection.Assembly.GetExecutingAssembly()));
Image img = (Bitmap)rm.GetObject("resourcesimagename.jpg");

MODI Document Create path

I am currently working in an OCR reader using MODI dll and my code is like
MODI.Document md = new MODI.Document();
//image path
string fileToOCR="C:\\temp\\1in.jpg";
md.Create(fileToOCR);
md.OCR(MODI.MiLANGUAGES.miLANG_ENGLISH, true, true);
MODI.Image img = (MODI.Image)md.Images[0];
MODI.Layout layout = img.Layout;
layout = img.Layout;
string result = layout.Text;
md.Close(false);
And I want to use
//image path
string fileToOCR="C:\\temp\\1in.jpg";
to
//image path
string fileToOCR="http://example.com/image.png";
How this possible, please help me.

MODI needs a local file to work on. You can use WebClient.DownloadData (see http://msdn.microsoft.com/en-us/library/xz398a3f.aspx) to get the data, then save it locally.

Path to an embedded resource file

I have an icon in my resource file , which I want to reference.
This is the code that needs that path to an icon file:
IWshRuntimeLibrary.IWshShortcut MyShortcut ;
MyShortcut = (IWshRuntimeLibrary.IWshShortcut)WshShell.CreateShortcut(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory) + #"\PerfectUpload.lnk");
MyShortcut.IconLocation = //path to icons path . Works if set to #"c:/icon.ico"
Instead of having an external icon file I want it to find an embedded icon file.
Something like
MyShortcut.IconLocation = Path.GetFullPath(global::perfectupload.Properties.Resources.finish_perfect1.ToString()) ;
is this possible ? if so how ?
Thanks

I think this should work, but I can't remember exactly (not at work to double check).
MyShortcut.IconLocation = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("YourNamespace.IconFilename.ico");

Just expanding on SharpUrBrain's answer, which didn't work for me, instead of:
if (null != stream)
{
//Fetch image from stream.
MyShortcut.IconLocation = System.Drawing.Image.FromStream(stream);
}
It should be something like:
if (null != stream)
{
string temp = Path.GetTempFileName();
System.Drawing.Image.FromStream(stream).Save(temp);
shortcut.IconLocation = temp;
}

I think it will help you in some what...
//Get the assembly.
System.Reflection.Assembly CurrAssembly = System.Reflection.Assembly.LoadFrom(System.Windows.Forms.Application.ExecutablePath);
//Gets the image from Images Folder.
System.IO.Stream stream = CurrAssembly.GetManifestResourceStream("ImageURL");
if (null != stream)
{
//Fetch image from stream.
MyShortcut.IconLocation = System.Drawing.Image.FromStream(stream);
}

The res protocol may be able to help you with this: http://msdn.microsoft.com/en-us/library/aa767740(v=vs.85).aspx

In WPF I have done this before:
Uri TweetyUri = new Uri(#"/Resources/MyIco.ico", UriKind.Relative);
System.IO.Stream IconStream = Application.GetResourceStream(TweetyUri).Stream;
NotifyIcon.Icon = new System.Drawing.Icon(IconStream);

The resource it is embedded, so incapsulated in a DLL assembly. So you cannot get its real path, you have to change your approach.
You would probably want to load the resource in memory and write it down to a temp file, then link it from there. Once the icon is is changed on the destination file, you can delete the icon file itself.

How do I retrieve an image from my resx file?

I have added an image to my form's resource file, myForm.resx, and I would like to use it in my code file, myForm.cs, but I am not entirely clear on how to get a handle to it.

You can just use Visual Studio to add it (Project, Properties, Resources, Add existing file), and then access it by name:
Bitmap bmp = Properties.Resources.<name_you_gave_it>;

See MSDN for ResourceManager
rm = new ResourceManager("Images", this.GetType().Assembly);
pictureBox1.Image = (System.Drawing.Image)rm.GetObject("flag");

The following code is extracted from this link
// Creates the ResourceManager.
System.Resources.ResourceManager myManager = new
System.Resources.ResourceManager("ResourceNamespace.myResources",
myAssembly);
// Retrieves String and Image resources.
System.String myString;
System.Drawing.Image myImage;
myString = myManager.GetString("StringResource");
myImage = (System.Drawing.Image)myManager.GetObject("ImageResource");

pictureBox1.Image = new Bitmap (global::<<project namespace>>.Properties.Resources.<<Filename>>);
Like the following, the one I implemented:
pboxSignedInStaffIcon.Image = new Bitmap(global::EasyRent.Properties.Resources.worker1);
