Though this code appears to work, I suspect it could be streamline.
Total Noob Here.
public bool isit(string c1)
{
string color1 = "blue green red";
Regex re = new Regex("@"+c1, RegexOptions.IgnoreCase |
RegexOptions.Multiline);
if (re.Matches(color1).Count 0)
{
return (true);
}
else
{
return (false);
}
==
I found a sample on the net that does this
if (re.color1 != 0 )
But I get an error about Regex not having a definition for color1
==
Also, what if color1 was an enum, how would test the search string can
be found in any of the items? 5 2889
how about
switch(c1) {
case "blue":
case "green":
case "red":
return true;
default:
return false;
}
More generally, you could use
return re.IsMatch(color1);
If it was an enum, then the Enum helper class can do a lot (i.e. list
available items, parse items, etc); e.g.
enum MyColors { Blue, Red, Green };
static void Main(string[] args) {
Console.WriteLine(IsColor("blue"));
Console.WriteLine(IsColor("red"));
MyColors value;
if (TryMatchColor("green", out value)) {
Console.WriteLine(value);
}
if (TryMatchColor("turquoise", out value)) {
Console.WriteLine(value);
}
}
static bool IsColor(string name) {
MyColors color;
return TryMatchColor(name, out color);
}
static bool TryMatchColor(string name, out MyColors value) {
try {
value = (MyColors) Enum.Parse(typeof(MyColors), name, true);
return true;
} catch (ArgumentException) {
value = 0; // default
return false;
}
}
OK - reading again I may have missed your intention... forgetting about
solving it via Regex (or any other approach) - what exactly are you trying
to do? i.e. input {x}, output {y}...?

The post with the array is going to work.. I wanted to use Regex
because some of the entries will be sentences and I might need to
search for patterns. I know I just asked for a boolean, but Ideally I
wanted to return an array of every entry where the pattern was found.
Thank you!

Thank you.. this is a great help.
if you have it handy.. what if the enteries were very long sentences
and It was a pattern I was searching for (I simplified my original
question). And what if I wanted to return an array of lines that had
the match. I know I might be pushing it and if so I'll go dig around -
I have a very similar VB code I'm trying to migrate over.
Thanks again - really appreciate it! This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
