i need to check if my textbox doesn't contain specific string "Fold". I used to do this like this
if (textbox.Text.Contains("Fold"){}
else { do stuff }
but now i need some alternative of this.

4Why do you have an alternative? This is the simplest way.Soner Gönül– Soner Gönül2015-12-19 14:48:19 +00:00Commented Dec 19, 2015 at 14:48

im checking 4-5 things at a time and i will have to do a lot of if statements also there's quite some code if the statement is true and i will have to either make it into new method or copy and paste it ..kopelence– kopelence2015-12-19 14:49:07 +00:00Commented Dec 19, 2015 at 14:49

You need to reverse the boolean:
if (!textBox.Text.Contains("Fold")) { ... }
Or you can compare with false as @adv12 said:
if (textBox.Text.Contains("Fold") == false) { ... }

Thanks to adv12 i found this piece of code to work perfectly
if (textBox.Text.Contains("Fold")==false)
or
if (!textBox.Text.Contains("Fold"))

You can get in a real time using TextChanged event of the TextBox. Much better way before users submits their result.
