How do you determine if a letter is in the range from A-Z or Digit 0-9? We are getting some corrupted data ‘I_999Š=ÄÖÆaðøñòòñ’.
I thought I could use Char.IsLetterOrDigit(‘Š’) to ID the corrupted data from ‘I_999Š’, but unexpectedly this is returning true. I need to trap this, any thoughts?
Well there are two quick options. The first is to use a regular expression the second is to use the Asc() function to determine if the Ascii value is in the range of those allowable characters. I would personally use Asc() for this.
