C# Dynamic If arugment

Building a WPF application in C# I have 5 check boxes and when one or more is selected I want the argument of a it statement to change dynamically. For example, I have Mon, Tue, Wed, Thu & Fri as the check boxes. If user selects Mon, Wed, & Fri then I want the argument for a if statement to change to reflect that. I don't want to make numerous different if statements. Here is a sample I wrote, but the if statement is wrong obviously

string passArg = "";

        if(check_mon.IsChecked == true)
        {
            passArg = "passArg == \"Mon\"";
        }

        if(passArg)
        {
            MessageBox.Show("RAN");
        }

Sorry if this is a dumb question

You can fire an event when the checkbox is Checked or Unchecked and in this method you can set or unset your stuff.
For example in your xaml form: 

<CheckBox Checked="Checked" Unchecked="UnChecked"/>

And then create the events: 

private void UnChecked(object sender, RoutedEventArgs e) {
    //Checked, enable, disable or do whatever you want
}
private void Checked(object sender, RoutedEventArgs e) {
    //Checked, enable, disable or do whatever you want
}

Not as simply as you would like. You can generate code dynamically but it's overkill in this case. All you need is:

bool isChecked = false;

if(check_mon.IsChecked && passArg == "Mon")
{
    isChecked = true;
}
...

if(isChecked)
{
    MessageBox.Show("RAN");
}

I don't want to make numerous different if statements.

Well, you could put the checkboxes in a loop, set the Tag or some other property and compare that against pasArg but I tend to go with the simplest solution that works first then focus on making it better. You may find that you spend more time trying to come up with a clever solution (that you may not understand later) when 7 if statements would work just fine.

You can check for a value in a list:

List<string> checked = new List<string>()

if (check_mon.IsChecked)
{
   checked.Add("Mon");
}

if (checked.Contains(passArg))
{
   MessageBox.Show("RAN");
}
