Remove all non-ASCII characters from string

Question

I have a C# routine that imports data from a CSV file, matches it against a database and then rewrites it to a file. The source file seems to have a few non-ASCII characters

Answer 1

If you wanted to test a specific character, you could use

if ((int)myChar <= 127)

Just getting the ASCII encoding of the string will not tell you that a specific character was non-ASCII to begin with (if you care about that). See MSDN.
