In LINQ, you can remap properties by using the Select method to project the properties to a new form. This allows you to transform and modify the properties of objects in a collection.
To remap properties in LINQ, you can use anonymous types to create a new object with the desired properties. For example, you can select specific properties from an object and assign them to new property names or types.
You can also use the Select method with lambda expressions to remap properties dynamically based on conditions or transformations. This allows you to customize the mapping logic based on your specific requirements.
Overall, remapping properties in LINQ gives you the flexibility to manipulate and transform data in a collection based on your specific needs and criteria.

What is property transformation in LINQ result set?
Property transformation in LINQ result set refers to the process of modifying or transforming the properties of the elements in the result set returned by a LINQ query. This can be done using methods like Select, SelectMany, or projections, which allow for mapping, filtering, or aggregating the properties of the objects in the result set. This transformation can be used to manipulate the data in the result set to better suit the needs of the application or to perform calculations or other operations on the properties of the objects.
What is property renaming in LINQ?
Property renaming in LINQ refers to the ability to alias or rename property names in the query results. This can be useful when dealing with data from multiple sources that may have different naming conventions for the same properties. By using property renaming, developers can provide more meaningful and consistent names for the properties in the query results. This can be done using the select clause in LINQ queries, where developers can use the new keyword to create objects with renamed properties.
How to rename properties in LINQ to Objects queries?
In LINQ to Objects, you can use the select clause to rename properties in queries. Here's an example of how to rename a property in a LINQ to Objects query:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
// Define a class with the original property name public class Person { public string Name { get; set; } } // Create a list of Person objects List<Person> people = new List<Person> { new Person { Name = "Alice" }, new Person { Name = "Bob" } }; // Rename the Name property to FullName in the query var renamedProperties = from p in people select new { FullName = p.Name }; // Iterate over the results and access the renamed property foreach (var person in renamedProperties) { Console.WriteLine(person.FullName); } |
In this example, the select clause is used to create a new anonymous type with a property named FullName that contains the value of the original Name property. This allows you to effectively rename the property in the query results.
How to rename properties in LINQ to SQL queries?
In LINQ to SQL, you can rename properties in queries by using the select clause. Here's an example of how you can rename a property:
1 2 3 4 5 6 7 |
var query = from p in db.Products select new { ProductId = p.ProductID, ProductName = p.ProductName, UnitPrice = p.UnitPrice }; |
In this example, we are renaming the ProductID property to ProductId, ProductName property to ProductName, and UnitPrice property to UnitPrice.
You can use this renamed property in your further query operations.
