How can I determine in C# whether a SQL Server database column is autoincrement?

Question

I need to be able to determine from the DataTable returned by DbConnection.GetSchema() whether a particular column in a SQL Server table is identity/auto-increment or not.

Answer 1

DataTable has Columns property and DataColumn has a property indicating auto-increment:

bool isAutoIncrement = dataTable.Columns[iCol].AutoIncrement
