Is it possible in LINQ to join on multiple fields in a single join? EDIT. var result = from x in entity join y in entity2 on new { x.field1, x.field2 } equals new { y.field1, y.field2 } is the solution I referenced as assuming an equijoin above. Further EDIT
You just need to name the anonymous property the same on both sides. on new { t1.ProjectID, SecondProperty = true } equals new { t2.ProjectID, SecondProperty = t2.Completed } into j1. Based on the comments of @svick, here is another implementation that might make more sense:
You can join two tables on multiple columns by using the `on` clause multiple times. For example, the following code joins the `customers` and `orders` tables on the `CustomerId` and `OrderId` columns:
29 maj 2024 · The join methods provided in the LINQ framework are Join and GroupJoin. These methods perform equijoins, or joins that match two data sources based on equality of their keys. (For comparison, Transact-SQL supports join operators other than equals, for example the less than operator.)
A LINQ join on multiple columns is a way to combine data from two or more tables in a single query. This is done by using the `Join` method. The `Join` method takes two or more tables as input, and a join clause that specifies how the tables are related.
4 wrz 2022 · With Entity Framework Core we can use the Join () extension method from the System.Linq library. What the Join method does is to correlate (or join) elements of two sequences using based on matching keys. Let us look at an example on how to join two tables using Entity Framework Core and the Join () method.
7 wrz 2023 · The method syntax allows you to use extension methods to perform the same query: int[] numbers = { 2, 8, 4, 9, 3, 6, 1, 7, 5 }; var largerThanFive = numbers.Where (x => x > 5); What is The LINQ Join Operator? When working with data, a common scenario is having two data sources that you want to combine based on some criteria.
