What’s the best way to bulk database inserts from c#?

Question

How do I/what’s the best way to do bulk database inserts?

In C#, I am iterating over a collection and calling an insert stored procedure for each item in the collect

Answer 1

Create a XML document that contains all the items to be inserted. Then inside of a stored procedure, use the TSQL xml support (OPENXML) to read all the data from the XML document and insert it into your tables with hopefully one insert statement for each table.

However if you are only inserting data into a single table and don’t need any database side logic, why not use SqlBulkCopy?
