Question

How can I improve the performance if this Code snippet.

bool OrSetFinalResult =true;
string OrSet = "(1&1)|0";
string[] AndSets = OrSet.Split('&');
foreach (string AndSet in AndSets)
{
    if (AndSet == "0")
    {
        // A single "false" statement makes the entire And statement FALSE
        OrSetFinalResult = false;
        break;
    }
}

Is there any way to remove the ForEach loop with any of the LINQ expressions ?

Answer 1

Sounds like:

if (AndSets.Contains("0"))
{
    OrSetFinalResult = false;
}

No need for LINQ at all. It’ll still loop internally of course, but it’s still a lot simpler.

EDIT: As noted in comments, you could also use:

OrSetFinalResult = OrSetFinalResult && !OrSet.Split('&').Contains("0");
