Question

I have a color dictionary as shown below.

Dictionary<string, List<System.Drawing.Color>> channelColorInformation = 
    new Dictionary<string, List<System.Drawing.Color>>();

List<System.Drawing.Color> colorInfo = new List<System.Drawing.Color>();

System.Drawing.Color color = System.Drawing.ColorTranslator.FromHtml("#FFF0F8FF");
colorInfo.Add(color);
color = System.Drawing.ColorTranslator.FromHtml("#FFFAEBD7");
colorInfo.Add(color);
color = System.Drawing.ColorTranslator.FromHtml("#FF00FFFF");
colorInfo.Add(color);
channelColorInformation.Add("Channel1", colorInfo);

How do I get the System.Drawing.Color information from the dictionary for Channel1 at index 0, 1, 2?

Answer 1

Something like this:

List<Color> listForChannel1 = channelColorInformation["Channel1"];
Color c1 = listForChannel1[0];    
Color c2 = listForChannel1[2];    
Color c3 = listForChannel1[3];

UPDATE

@Jon’s answer is also relevant because it shows two options for dealing with the possibility that the key is not present in the dictionary.
