You can remove all control characters from your input string with something like this:
string input; // this is your input string
string output = new string(input.Where(c => !char.IsControl(c)).ToArray());
Here is the documentation for the IsControl()
method.
Or if you want to keep letters and digits only, you can also use the IsLetter
and IsDigit
function:
string output = new string(input.Where(c => char.IsLetter(c) || char.IsDigit(c)).ToArray());
