There is no bulk update. If you don't want to update the data table row by row (via data adapter), you need to build the infrastructure yourself. For example bulk insert the data into a temporary table then run a command or stored procedure to do the update.

Solution 1

Can you explain in more detail,
if you want to update some data and insert some data in same table basis some validation go for merge statement.

You can send the datatable to your database using .net.
Depends how much data you are passing.

Solution 2

My advise would be like

1. Build an XML string of the data you like to update.

2. Send the XML string to a new Stored Procedure which will parse the XML string

3. Use SQL Merge statement to update all the values in one go!

You can do google to get more precise details!
