converting string to integer, subtracting strings.


 I have a textbox into which the user will enter a number

I then have button that when the user clicks, the number taken from the textbox will be subtracted by one or more(depending on the users situation) and displayed in a label.  

The problem i am having at the moment is that when i attempt to do this an error comes up saying that "the operator '-' cannot be used with string or int".

String Score1 = txtScore1.Text:

String netScore1;


netScore1 = Score1 - 1;

lblNetScore1.Text = netScore1;


I have also tried to declare my variable as an integer but it wont allow me to implicity convert a string to an integer.

int score1 = txtScore1.Text: 


any suggestion?

Hi guys, I was wondering the difference between small letter string type and a capital letter String type. Does anyone know about this? Highly appreciate for your answers! Thankz! The "proper" version is String, as it references the System.String class of the .NET Framework Class Library. The ability to use string is provided by C#, where it is an alias to String. Similarly, the "proper" version of an integer is Int32, as it references System.Int32.  The ability to use int is provided by C#, and the ability to use Integer is provided by VB.NET, and both int and Integer are aliases...
