Assembly: System.Data (in system.data.dll)
String always uses the default CultureInfo from the current thread, but SqlString contains its own locale Id and compare flags. The comparison result of two SqlString structures is independent of operating system and current thread locale.
When you use SqlString comparison operators, note that if the LCIDs of arguments are different, comparison functions throw an exception because they cannot be compared. For example, the statement
SqlString mySqlString = new SqlString("abc");
is equivalent to
SqlString mySqlString = new SqlString("abc", CultureInfo.CurrentCulture.LCID);
