Compiler Error CS0744
Expected contextual keyword 'equals'
The pattern for a join clause is join...in...on...equals, as shown in this example:
var query = from x in array1
join y in array2 on x equals y
select x;
To correct this error
- Add the equals keyword to the join clause.
Example
The following code generates CS0744:
// cs0744.cs
using System;
using System.Linq;
public class C
{
public static int Main()
{
int[] array1 = { 1, 2, 3 ,4, 5, 6,};
int[] array2 = { 5, 6, 7, 8, 9 };
var c = from x in array1
join y in array2 on x y // CS0744
select x;
return 1;
}
}
