Some time ago, the project involved the conversion between MySQL and MSSQL data types. Recently, I was studying Sina Weibo's API, which involved the conversion of GMT time types with time zones, this is a special record for future query.

In this series, we mainly introduce the basics of LINQ to SQL. Because of the powerful nature of LINQ, it has different contents for different data sources, this includes the SQL Server database's LINQ to SQL, the XML document's LINQ to XML, and the
