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 that are fouling up the processing routine.

I already have a static method that I run each input field through but it performs basic checks like removing commas and quotes. Does anybody know how I could add functionality that removes non-ASCII characters too?

Answer 1

Here a simple solution:

public static bool IsASCII(this string value) {     // ASCII encoding replaces non-ascii with question marks, so we use UTF8 to see if multi-byte sequences are there     return Encoding.UTF8.GetByteCount(value) == value.Length; }

Answer 2

string sOut = Encoding.ASCII.GetString(Encoding.ASCII.GetBytes(s))
