Question

How can you strip non-ASCII characters from a string? (in C#)

Answer 1

This is not optimal performance-wise, but a pretty straight-forward Linq approach:

string strippedString = new string(
    yourString.Where(c => c <= sbyte.MaxValue).ToArray()
    );

The downside is that all the "surviving" characters are first put into an array of type char[] which is then thrown away after the string constructor no longer uses it.
