If you have to hit that limit, you've got bigger issues with your application...

It's System.Int32.MaxValue, or 2,147,483,647. But since you wont be able to reach that limit without generating an OutOfMemory Exception, it's limited by available memory.

You can find the limitations in MSDN but I don't have a link.

From MSDN[^]:

To add rows to a DataTable, you must first use the NewRow method to return a new DataRow object. The NewRow method returns a row with the schema of the DataTable, as it is defined by the table's DataColumnCollection. The maximum number of rows that a DataTable can store is 16,777,216. For more information, see Adding Data to a DataTable.
