I want to add values within list of dates using datatable.compute.
List of dates as follows
var dates = Enumerable.Range(0, 7).Select(days => monday.AddDays(days)).ToList();
And I want compute the values in those days.I don't know how to use filter with the list. I've tried following method but no luck.
sumObject1 = table.Compute("Sum(Amount)", "Type='Income' AND Date = dates");
Rest of the code works fine.
CodePudding user response:
You can use LINQ for that:
table.AsEnumerable().Where(r => r["Type"]?.ToString() == "Income" && dates.Contains((DateTime)r["Date"]))
.Sum(rs => (decimal)rs["Amount"]);
You won't be able to use the list with the DataTable expressions.
