conerting string to long

for the following piece of code:
long Priority = Convert.ToInt64(IsPdto.Priority);

I want to make sure that I do not get a runtime error, in case IsPdto.Priority is not a number in string format. How can I make sure that I do not perform this operation if it is not convertible to int?

you need to use long.TryParse method


long Priority = 0;
bool isCorrect = long.TryParse(IsPdto.Priority, out Priority);
if(isCorrect)
{
// 
}

If you want, you could put it in a try catch and ignore the error. For example:

try
{
long Priority = Convert.ToInt64(IsPdto.Priority);
}
catch
{
}

Since the error is handled by the code (even though it doesn't do anything), a runtime error won't occur. If you want you can even generate your own error message in your catch statement if it's a field that must be a valid numeric or you can set Priority to 0 if the field doesn't matter.
