Question

I need to save to a different setting based on the input string. Why will this line not work?

Properties.Settings.Default + colorOptionNametoSave = selectedIndexString;
Properties.Settings.Default.Save();

Where the colorOptionNametoSave is a different color setting and the selectedIndexString is the value to save. However I get the message:

Error 2: The left-hand side of an assignment must be a variable, property or indexer.

The only work around I can think of is a switch statement, but I have a lot of colors so that would be really long. Any ideas on a more efficient solution?

Answer 1

if/else or a switch is what you are looking for.

You cannot concatenate a variable name!

So a solution for you would be something like this ( if colorOptionNametoSave is a string ):

if(colorOptionNametoSave == "Blue")
{
    Properties.Settings.Default.Blue = selectedIndexString;
}
else if(colorOptionNametoSave == "Red")
{
    Properties.Settings.Default.Red = selectedIndexString;
}
