Help checking BackgroundImage

I am using this code to check a backgroundimage:

 if (actionbox1.BackgroundImage == "WaterforMGC.strollinstu.png")

But I get the error Operator '==' cannot be applied to operands of type 'System.Drawing.Image' and 'string'

So how can I开发者_StackOverflow中文版 check the BackgroundImage property?

Just in case, here's my randomizing code:

        //actionbox1
        var imageNames = new List<string> { "WaterforMGC.strollinstu.png", "WaterforMGC.blank.png", "WaterforMGC.swoopinstu.png", "WaterforMGC.waterbottle.png", "WaterforMGC.goop.png", "WaterforMGC.blank.png" };
        var rand = new Random();
        var index = rand.Next(0, imageNames.Count - 1);
        var s = this.GetType().Assembly.GetManifestResourceStream(imageNames[index]);
        actionbox1.BackgroundImage = Image.FromStream(s);

One solution could be simply first load, folowing your example, WaterforMGC.strollinstu.png file into System.Drawing.Image object, and after assign it to the actionbox1.BackgroundImage.

At the moment when you wnat to figure out the exact image, should be enough to check equality between two objects (which actually will call GetHashCode())

Example:

   //somewhere in the code 
   Image img1 = Image.FromFile(@".\.\....\\.\WaterforMGC.strollinstu1.png"); 
   Image img2 = Image.FromFile(@".\.\....\\.\WaterforMGC.strollinstu2.png");

   //assign to back image IMG1
   actionbox1.BackgroundImage = img1;



  //when comes moment to check whcih image is assigned (base on your app logic) 
  if(actionbox1.BackgroundImage == img1) 
  {
     //do somethinmg here, based on your logic
  }
  else if(actionbox1.BackgroundImage == img2) 
  {
     //do somethinmg other, based on your logic
  } 

Hope this helps.

Regards.
