Cannot convert from Models.Class to DbContext.Class using Entity Framework and ASP.NET MVC

I'm using a database first approach and I want to insert some data into the database. I am using this code:

public ActionResult Create(StudentDetails studentDetails)
{
    using (StudentRecordManagementEntities1 obj = new StudentRecordManagementEntities1())
    {
         obj.StudentDetails.Add(studentDetails);  //throws error
    }
}

Model class:

public class StudentDetails
{
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int Id { get; set; }
    public string Name { get; set; }
    public Nullable<long> ContactNumber { get; set; }
    public string Address { get; set; }
    public decimal Fees { get; set; }
    public bool isPaid { get; set; }
}

Error details:

Error CS1503 Argument 1: cannot convert from 'StudentRecordManagement.Models.StudentDetails' to 'StudentRecordManagement.Models.StudentDetail' StudentRecordManagement*

If you need more details, kindly let me know.

It looks like your model class is StudentRecordManagement.Models.StudentDetail, however you are inserting StudentRecordManagement.Models.StudentDetails. So what you can do is to give necessary type to your Database model:

public ActionResult Create(StudentDetails studentDetails)
{
    using (StudentRecordManagementEntities1 obj = new StudentRecordManagementEntities1())
    {
        var studentDetail = new StudentRecordManagement.Models.StudentDetail {
         Name = studentDetails.Name,
         // the other code is omitted for the brevity
     };
     obj.StudentDetails.Add(studentDetail);  //
}
