[RESOLVED] Why exception cannot be raised

Hi,

why can't I detect it as an exception, when tb_ite.Text is having "b" inside?

int int1;
                try
                {
                    int.TryParse(tb_ite.Text, out int1);
                }
                catch (Exception ex)
                {
                    ...
                }
                finally
                {
                }

Becoz u r tyring to parse here, it would have thrown exception if u used
Int32.Parse instead.

The TryParse method is like the
Parse method, except the
TryParse method does not throw an exception if the conversion fails. It eliminates the need to use exception handling to test for a
FormatException in the event that
s is invalid and cannot be successfully parsed.

tryparse is cobination Try and Parse

If any exception will return false

this to avoid exception message.

Whatever the result you will not get exception.

Hi,

Just see the documentation :
http://msdn.microsoft.com/en-us/library/system.int32.tryparse.aspx

TryParse doesn't though an exception. Instead it return a boolean value that tells if the conversion is value so you could check the return value for the TryParse function rather than having a try/catch construct.
