DateTime.TryParse century control C#

I have a C# app that’s importing data from a .DBF file, and inserts it into SQL Server. There’s a DOB column in the file with the dreaded MM/dd/yy format. I just use the Convert.ToDateTime, and most data converts to the 1900’s like I expected it to. There are a handful of records that don’t convert correctly and have people born 30 years from now. How do I force the conversion to only write MM/dd/19XX?

So for example this date in the .DBF file 12/29/29 gets converted to 12/29/2029.

I’m reading the .DBF file like so:

 var fileInfo = new System.IO.FileInfo(dbfPath);
            string dsPath = fileInfo.DirectoryName.ToString();

            DataSet DSResult = new DataSet();
            using (OleDbConnection cn = new OleDbConnection(
          @"Provider=Microsoft.Jet.OLEDB.4.0;" +
          @"Data Source=" + dsPath + ";" +  //Set the Data Sourde = to the directory of the file.  
          @"Extended Properties=dBASE III;"))

            using (OleDbCommand cm = cn.CreateCommand())
            {
                cn.Open();
                cm.CommandText = "SELECT * FROM UPDATED"; //Specify the file name for the select statement.  
                using (OleDbDataAdapter dba = new OleDbDataAdapter(cm))
                {


                    dba.Fill(DSResult);

                }
            }


            return DSResult;

You can change the Calendar.TwoDigitYearMax property to change the last year of the 100 year range.

DateTimeFormatInfo formatProvider = new DateTimeFormatInfo();
formatProvider.Calendar.TwoDigitYearMax = DateTime.Now.Year;

DateTime date = DateTime.ParseExact("12/12/22", "MM/dd/yy", formatProvider);
