get an integer from a text box.

[Guest]

Is there some way to convert a string which consists of a number(eg. 24) to an integer type? I am trying to get the value from the text property of a text box.

 

[Klaus H. Probst]

int n = int.Parse("24");
int n = int.Parse(TextBox1.Text);

[Eric Johannsen]

int n = int.Parse("24");

int n = int.Parse(TextBox1.Text);

Be sure to wrap that code in a try...catch block in case someone enters
invalid data, like this:

try
{
int n = int.Parse("24");
int n = int.Parse(TextBox1.Text);
}
catch (Exception ex)
{
// Do something to indicate TextBox1 does not contain a valid integer
}

You could also trap for the specific exceptions that Parse can throw, which
are FormatException, ArgumentException and OverflowException.

Hi owyn,

You can look into C# checked and unchecked keywords. It will throw exceptions if string -> int fail to work.

Correct me if i am wrong. Thanks.
