How can I set a variable to be at least a minimum value with C#

Question

I have this code:

Current.Resources["CardSetIconWidth"]   = (width-30)/260 * 160;

I would like to ensure that Current.Resources["CardSetIconWidth"] is always at least a minimum of 160.

Is there an easy way that I can do this?

Answer 1

Try this:

Current.Resources["CardSetIconWidth"] = Math.Max((width - 30) / 260 * 160, 160);

Answer 2

After the assignment, you could do

if (Current.Resources["CardSetIconWidth"]<160) Current.Resources["CardSetIconWidth"]=160;

Another option would be to use @rfmodulator answer into the indexer of a class:

public class SafeValues
{
    private readonly IDictionary<string, int> _dict = new Dictionary<string, int>();

    public int this[string key]
    {
        get { return _dict[key]; } // you can also choose to use Math.Min 
                                   // in the getter to keep the original values in the underlying dictionary
                                   // for debug purposes

        set { _dict[key] = Math.Max(value, 160); }
    }
}

So you can use it like

var Resources = new SafeValues(); // you can easily set a parameter for the min value in the constructor if you want
Resources["CardSetIconWidth"] = (width-30)/260 * 160;
