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.
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.
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:
