String comparion against a set of string values
.net, c#, string
Solution
There are many ways of doing it. One would be as follows:
var target = new HashSet<string>{ "abc", "efg", "lmn" };
if (target.Contains(x)) {
...
}
At max [my list of strings] can grow to 50 strings which is a rare possibility.
Then you should make `target` a `static readonly` in your class, like this:
private static readonly StringTargets = new HashSet<string>{ "abc", "efg", "lmn" };
Doing so would ensure that the set is created only once, and is not re-created each time the execution goes through the method that uses it.
Problem
I have a function like this(foo): I need to compare the input string and perform a task accordingly . Task is same, but only for a selected set of values. For all other values do nothing. ``` function foo(string x) { if(x == "abc") //do Task1 if(x == "efg") //do Task1 if(x == "hij") //do Task1 if(x == "lmn") //do Task1 } ``` Is there any other means to do checking other than this? Or putting `OR` operator inside `if`? What is the preferred way?
