If your StudentModel has the same properties as your Student entity class, you could map their property values.

var student = new Student 
{
  StudentId = studentModel.ID,
  Name = studentModel.Name,
  Address = studentModel.Address
}

context.Students.Add(student);
context.SaveChanges();

The rows value are repeating because you have your print statement inside the for loop. So what's happening is that the randomized value for a specific index is printed each iteration. Placing the print statement outside the for loop will fix this.

Also, I suggest placing the if statement that checks if all the randomized numbers are equal to the input numbers INSIDE the for loop then place a break statement at the end so it would break out of the loop if true.

It says SuspensionManager Failed. How do I exactly view the stack trace? But anyway other than that, my app is running how it should. It's saving/loading state properly.

SuspensionManagerException was unhandled by user code

Wow. Thank you so much for the help! It's working now!
