How to Find the Person with the Minimum or Maximum Property Value Using LINQ?

Object

To find the

object with the smallest attribute value, you can use the aggregation function of Linq. Please consider the following methods:

DateOfBirth The following is its working principle: Person

var firstBorn = People.Aggregate((curMin, x) => (curMin == null || (x.DateOfBirth ?? DateTime.MaxValue) < (curMin.DateOfBirth ?? DateTime.MaxValue)) ? x : curMin);

The method is used to traverse the collection and accumulate a single result.

• The anonymous function passed to uses two parameters: Aggregate

: The current minimum
• value I encountered so far (if no value is found, it is null).

  Aggregate : The current

  object being processed.
  • curMin DateOfBirth
  Condition Check whether
  • whether it has effective x values; if it is NULL, set it to Person (assuming that there is no valid
  value exceeding this value).

• Compare determine which object has earlier birth date. (x.DateOfBirth ?? DateTime.MaxValue) x DateOfBirth DateTime.MaxValue The cumulative process continues until all the DateOfBirth objects in the assessment set will eventually produce the

  object with the earliest value of
.

• (curMin == null || (x.DateOfBirth ?? DateTime.MaxValue) < (curMin.DateOfBirth ?? DateTime.MaxValue))

  This Revied Explanation Clarifies the Comparison Logic Within the Aggregate Method, Making the Process Easier to Unders.
