string.format if else statement

Question

How would I do if statement in string.format? I need to check if x=0, x=1 or x=null I know I can do with two values but I am not sure how to add another else statment here

String.Format("{0}", x == 0 ? "True" : "False")

What's the type of x? (If it's an int, it can't be null...) — Jon Skeet

And why are you using string.Format when the result is just the True or False string? You really need a more complete example before we can help you much... — Jon Skeet

hey Jon... I am rendering my title on my grid column. Therefore I need to format the title with my json data — EagleFox

That doesn't explain why you'd use string.Format with just a format string of {0}. Nor does it tell us the type of x. Again, a better example is required. — Jon Skeet

guys... all I wanted to know was how to add another else statement in the string.format? Thanks to Alex. Now I have already got it working... Thanks for your concern though Jon :) — EagleFox

String.Format("{0}", x == null ? "<null>": (x == 0 ? "True" : "False"))

I don't like nesting of ternary ifs. In general case and depending on version of C# you use, you can try this:

var values = new Dictionary<int?, string>()
{
    { 0, "zero"},
    { 1, "one"},
    { 2, "two"},
    { null, "none"}
};

String.Format("{0}", values[x]);

IMO, tables always beat complex if statements for more than 3 values.

with more then 2-3 values it is far more readable then ternary if. Try adding another case to ternary if and see what's cleaner. Actually, don't add another, just express these 4 cases with it.

Thank you for this answer as well Zdeslav, but for my simple purpose, I am accepting Alex's answer

how to add another else statment here

Nesting of ?: is possible but almost always a bad idea.

A direct answer, assuming x is int? is to just use ( ) :

 String.Format("{0}", x == null ? "Null" : (x.Value == 0 ? "True" : "False"))

I wouldn't say it's always a bad idea. I've seen it put to very good effect - but I wouldn't do it within the method call here...

I already put 'almost' in front of that. My alternative isn't that great either, but that's also from the confusion about the type of x.
