How can I convert String to Int?

Question

I have a TextBoxD1.Text and I want to convert it to an int to store it in a database.

How can I do this?

Answer 1

As explained in the TryParse documentation, TryParse() returns a Boolean which indicates that a valid number was found:

bool success = Int32.TryParse(TextBoxD1.Text, out val);

if (success)
{
    // Put val in database
}
else
{
    // Handle the case that the string doesn't contain a valid number
}
