问题
Is there a fast, efficient way in VB.NET/ADO.NET to insert large amount of data from Geneneric.List(Of Integer) into SQL Server table besides looping thru the list and issuing individual INSERT commands? I am limited to .NET 3.5 and SQL Server 2005.
Thanks!

Ship XML with all the changes to a stored procedure.
Here is an old example here:

Here is a smaller example, but shows the basics.

Send xml to stored procedure. Shred the xml to a @variable or #temp table. Do your UPDATES / INSERTS (or MERGE/UPSERT) using the @variable or #temp table.

Another example.
What I like to do is create a strong dataset. Put your data into the strong dataset. Then send the ds.GetXml() to the stored procedure.
That way, you get strong typing (using the strong dataset), and you don't have to write your own xml-maker, you piggy back off of .GetXml(). Hint: After creating the strong dataset, remove the namespace (tempuri or something like that)
