I think a more readable and flexible option is to use Where function: var result = from x in entity1 from y in entity2 .Where(y => y.field1 == x.field1 && y.field2 == x.field2) This also allows to easily change from inner join to left join by appending .DefaultIfEmpty(). Share.
Every single example of joins in Linq to Entities involves only one column in the on clause. What is the syntax if I need 2 or more columns to make the join work?
Summary: * LINQ to DataSet supports multi-field joins using the Join method. * You can specify join conditions on multiple fields using the on clause and the equals keyword. * Alternatively, you can use the where clause to filter on multiple fields to achieve an equijoin.
Joining on Multiple Columns. 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: c var result = from customer in customers
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.
In LINQ, joining on multiple fields can be elegantly achieved by creating anonymous types that contain the fields you want to join on. This approach works well and is commonly used for equijoins. In the case of joins with additional conditions, you can indeed add those conditions to the where clause.
7 wrz 2023 · LINQ Inner Join With Multiple Conditions. If you want to use multiple conditions within your join, you can simply use more than one where clause. Let’s update our query once again:
