How to Sort a List by Object Property Using LINQ?

Use linq to list

Object attribute sorting

Question:

Suppose there is a class called Order, which includes Orderid, OrderDate, Quantity, and Total. There is now a list containing these Order objects that sort the list based on specific attributes (such as OrderDate or Orderid).

Using Linq solution:

The most direct method of sorting the attributes of List objects using linq is shown below:

In this example, ObjlistorDer is a list of ORDER objects. The OrderBY method is used to set up the order of the order of the OrderDate attribute. The result is assigned to the SortedList variable.

List<Order> SortedList = objListOrder.OrderBy(o => o.OrderDate).ToList();

Explanation:

The Orderby method accepts a lambda expression as a parameter, which attributes should be sorted in which attributes should be specified in this expression. In this example, Lambda expression o = & gt; O.OrderDate is used to access the OrderDate property of each Order object. The result of the OrderBY method is a sorted Ienumerable

sequence. In order to convert this sequence back to the list, the Tolist method is used. SortedList now contains a list of orderly Order objects.

This method can be easily modified to sort by any other attributes in the Order class. Just simply change the attribute names in Lambda expressions, such as O = & GT; O.O.orderid.

C language data structure: data representation and operation of trees and graphs C language data structure: data representation and operation of trees and graphs Apr 04, 2025 am 11:18 AM

C language data structure: The data representation of the tree and graph is a hierarchical data structure consisting of nodes. Each node contains a data element and a pointer to its child nodes. The binary tree is a special type of tree. Each node has at most two child nodes. The data represents structTreeNode{intdata;structTreeNode*left;structTreeNode*right;}; Operation creates a tree traversal tree (predecision, in-order, and later order) search tree insertion node deletes node graph is a collection of data structures, where elements are vertices, and they can be connected together through edges with right or unrighted data representing neighbors.
