Handling a text field that is null on reading

[Battwell]

If I read a text field string that is Null ( empty)
What is the best way to handle it before trying to convert to double etc?
As this throws an exception

[dezsoe]

Use TryParse:

Code: Select all

double fieldValue;

if (!Double.TryParse(AS3.Getfield(12345), out fieldValue))
{
  exec.AddStatusmessage("Cannot convert to double");
  return;
}

That works well
Thank you
