When using LINQ to DataSet, how can you perform aggregation operations such as sum, count, or average on grouped data?
- By applying the Where clause before grouping the data
- By directly calling the Aggregate method on the DataSet object
- By using the GroupBy clause followed by the aggregation function within the Select statement
- By utilizing the OrderBy clause to sort the data before applying aggregation
When using LINQ to DataSet, you can perform aggregation operations on grouped data by using the GroupBy clause followed by the aggregation function within the Select statement. This allows you to group the data based on a specific criterion and then apply aggregate functions such as sum, count, average, etc., to each group individually. Understanding how to leverage the GroupBy clause for aggregating data is crucial for performing complex data analysis tasks using LINQ to DataSet.
