I have solved my problem with adding two line of code

The new funciton will be…
static public string CleanString(string s)
{
if (s != null && s.Length > 0)
{
StringBuilder sb = new StringBuilder(s.Length);
foreach (char c in s)
{
//sb.Append(Char.IsControl(c) ? ‘ ‘ : c);
if(Char.IsSymbol(c))
{
continue;
}
sb.Append(Char.IsLetterOrDigit(c) ? c : ‘ ‘);

}
s = sb.ToString();
}
return s;
}

Thanks for sharing such nice function

Nido, see this webpage for the list of “control” characters that are removed:

As I mentioned in the article, the sample code does not remove high ASCII or UNICODE characters which may appear as binary. Run the sample code on your data, and see what binary characters still remain. Then add a check to the loop to remove those characters as well.
