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.
The way you'd do a join on more than one criteria generally is to use an anonymous type: join pc in productcategory on new { Id = p.Id, Other = p.Other } equals new { Id = pc.ProdId, Other = pc.Other }. This works in Linq-to-Objects, and I presume the same will work with database queries as well.
In this article, we’ll take a look at how to use LINQ to join multiple tables on multiple conditions. We’ll start by discussing the basics of LINQ joins, and then we’ll show you how to use LINQ to join tables on different columns, on the same column, and on multiple columns.
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.
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:
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.
LINQ joins allow you to combine data from two or more tables into a single result set. This can be useful for comparing data between tables, or for performing calculations that require data from multiple sources. In this tutorial, you will learn how to perform a LINQ join on multiple columns.
