StrComp
Definition: Returns a value indicating the result of a
string comparison.
Can we tell you whether two strings or identical? We can, provided you tell us one thing: do you want a case-sensitive comparison or a case-insensitive comparison?
Let’s try a case-insensitive comparison for starters. In the following set of commands we assign values to variables $ a and$b. We then use the System.Stringclass and the Compare( )method to compare the two strings. Note that we pass the Compare() method three parameters: the two strings to be compared, and the value $True, which indicates that we want to do a case-insensitive comparison:
$a = "dog"
$b = "DOG"
$c = [String]:
:Compare($
a,$b,$True)
When you run this command and then echo back the value of $c you should get the following:
0
Note. A 0 means that the strings are identical.Any other value means that the strings are notidentical.
Of course, these strings are identical because we did a case-insensitive comparison. Suppose we use thiscommand, which does a case –sensitive comparison:
$c = [String]:
:Compare($
a,$b,$False)
This time you get back -1, meaning that the strings are notidentical (because the letter cases are not the same).
