[jitheshborgia]

Thank you

Hi

What exactly do you mean by extract?
To address a specific image you can use the key of the image:

myImageList.Images["ImageKey"]

or find it by its index. I suggest supplying a key to each image you add to the ImageList as this makes the code more maintainable.

i mean how we can view the images from imageList?is it possible to add the images to a picture box one by one?

hi !!!

First drag and drop imageList control from your ToolBox to the form...
Go to the imagelist properties...and in there select Images property....select a few images.....
Set the ColorDepth Property to Depth32Bit..
this property determines the color resolution of your images...
Set the ImageSize property to the picture Box size.....
Put up a button in your form and a picture box too...
Declare a global variable such as int i=0;
Now Put up this code into thr button click event

 if (i < imageList1.Images.Count)
            {
                pictureBox1.Image = imageList1.Images[i];
                i++;
            }
            else
            {
                i = 0;
            }
 

this code will show images one by one in the image list.....and will keep revolving.......

ThatThatGuy was very helpful. It's amazing how hard it is to find a simple answer to this obvious question. Us VB6 guys new to C# .NET probably screw up by trying to use:

pictureBox1.Image = imageList1.Images("MyImageName");

That's how it looks in VB6, but here is how it looks in C# .NET (using BMPs imported into the imagelist):

pictureBox1.Image = imageList1.Images["MyImageName.bmp"]

There is no '.Item' member on the collection to let you use "()" instead of "[]" and the ".bmp" gets automatically included with the filename as the key. So simple! But all the examples are just loading images off the disc to the image list and/or getting the graphics object off the WinForm and drawing the image to that.
