C# Calculation using Data Table Compute

Question

I have been using C# Datatable.Compute function to do calculations.

Example:Dot net version 5.0

Given that , Datatable dt = new Datatable();

var a=4000

var b =24

var str = dt.Compute((a/b).ToString(), string.Empty);

The gen0 garbage collector invocation for this single operation is high.

Could you suggest an alternate function to this?

Answer 1

Probably you meant dt.Compute( $"{a} / {b}", string.Empty ).

Answer 2

its a rather heavy operation. the expression must be parsed, converted to il code, then loaded as an assembly.

note: if lambda existed, when designed, than they probably would have been used, and the expression compiled at build instead of runtime.
