Sometimes we may need to create the DataTable manually and some specific schema definitions, such as Foreign Key constraints, expression columns and so on.
In this sample, we will demonstrate how to create the DataTable manually with specific schema definitions:
1. Create multiple DataTable and define the initial columns.
2. Create the constraints on the tables.
3. Insert the values and show the tables.
4. Create the expression columns and show the tables.
You can find more code samples that demonstrate the most typical programming scenarios by using Microsoft All-In-One Code Framework Sample Browser or Sample Browser Visual Studio extension.
