Question

I am not very experienced in SQL. I am using SQL Server 2008, and MVC3; have a simple view in my Database, trying to make a list using the following script:

 List<vw_LearnerCourse> list = ctx.vw_LearnerCourses.Where(x => x.Course_ID == id).ToList().AsEnumerable();

I get the following error:

Cannot implicitly convert type 'System.Collections.Generic.IEnumerable<vw_LearnerCourse>' to 'System.Collections.Generic.List<vw_LearnerCourse>'. An explicit conversion exists (are you missing a cast?)

Would appreciate your assistance. Thanks in advance.

Answer 1

Call .ToList() on the IEnumerable.

List<vw_LearnerCourse> list = ctx.vw_LearnerCourses.Where(x => x.Course_ID == id).ToList();

From the documentation:

The ToList(IEnumerable) method forces immediate
query evaluation and returns a List that contains the query
results. You can append this method to your query in order to obtain a
cached copy of the query results.
