String from label.text weird behaviour

So I have a Label being initialized by a WebService. I want to see if that label contains any commas. The problem is, even if the label has commas, Contains() returns false and if I do a Split(), the array is only 1 element long, containing the entire string.

// text is "255,255,0,0"
string wat = myLabel.Text;
string[] wats = wat.Split(',');

// This IF never happens, for some reason
if (wat.Contains(","))
{
    anotherLabel.Text = wats[0] + " VS " + wats[1];
}

Why don't Split() and Contains() work? Can it be some kind of diferent encode in the string that comes from the label? If I do wat = wat + ",", then Contains()returns True.

Unicode symbols are often weird. Unicode has a lot of commas, e.g. 

string wat = "255，255，0，0"; // Full range commas

bool hasComma = wat.Contains(','); // false

If wat.Contains(',') returns false then delimiters are not commas ,. You can check it with string decoded:

string wat = myLabel.Text;

// Let's have a close look at wat: which characters (codes included) does it contain
MessageBox.Show(
  $"wat: [{wat}] encoded as {string.Join(" ", wat.Select(c => ((int)c).ToString("x4")))}");

You should get

wat: [255,255,0,0] encoded as 0032 0035 0035 002c 0032 0035 0035 002c 0030 002c 0030

if not check what character code(s) do you have instead of expected 002c.

The following line is always going to evaluate to false:

if (wats.Contains(","))

string.Split(',') will only return the values in between commas as you are specifying a comma as your delimiter. None of the items in the array will ever contain a comma.

If you want to check whether your label text contains commas simply do:

if (lblteste.Text.Contains(','))
