Trouble with NULL in C#

[rameshonweb]

HI
I created a simple windows application where in there is a textbox where I can enter values and iam using
int.Parse( this.textBox1.Text , NumberStyles.Number, CultureInfo.CurrentCulture )
to convert the entered string(which is a number) to a integer.
There is a button which performs certain action taking that number entered in the text.
The problem is when I delete the number in the text field to enter another number
it gives error

An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll

Additional information: Input string was not in a correct format.

Some one please help me to fix this.
Thanks in advance for the help

That means that this.textBox1.Text has charachters which cannot be converted to an int

Tyr the tryParse method which will give a boolen indicating if the operation was successful instead of throwing errors.

[rameshonweb]

is TryParse defined in .NET 1.1 framework?

oh, ok...

well...i checked out msdn here
Its new to 2.0 so definitely non-existant in 1.1

guess you would have to use try catches around parse

cheers
