Hi all,

I want to know if it is possible to check if multiple combinations of values are true for example:
I have 3 boolean values a, b and c andI want to check if a & b are true or a & c are true or b & c are true without doing:

csharp

if (((a == "true") && (b == "true")) || ((a == "true") && (c == "true")) || ((b == "true") && (c == "true")))
{
    //do stuff here
}


I know that this example isn't too bad but if there are more than 3 values it starts getting huge (4 is already twice as long as the one above).

Thanks in advance

Ian

Unfortunately, no. However, you can shorten the code. Boolean value comparisons do not require the == "true" part. You can simplify it like the following. Keep in mind that an IF statement evaluates to a boolean answer, as a result you do not need to spell out what it is comparing to when using boolean values.

As you can see it is much shorter and easier to read.
CODE

if ((a && b) || (a && c) || (b && c))
{
}


Hope that helps.
