I’ve been having error for a while now, and while reading all the other posts her on SO, I didn’t get much more cleaver.
When making a database call I get the error:
Index (zero based) must be greater than or equal to zero
I have the following method which gives me the error:
public bool IsUserInRole(User user, string roleName)
{
using (var repository = new SaxoPublishingEntities())
{
repository.Attach(user);
// THIS CALLS GIVE ME THE ERRROR
var roles = repository.UserRoles.Include("Users").Where(userRole =>
userRole.Name == roleName && userRole.Users.Contains(user)).ToList();
if (roles.Any())
{
return true;
}
return false;
}
}
My database model:

Any ideas is HIGHLY appreciated! 🙂
Attempted rewrite version 1:
public bool IsUserInRole(User user, string roleName)
{
using (var repository = new SaxoPublishingEntities())
{
var users = repository.Users.Where(c => c.Id == user.Id);
if (users.Any())
{
var myUser = users.First();
var roles = repository.UserRoles.Where(userRole =>
userRole.Name == roleName && userRole.Users.Contains(myUser)).ToList();
if (roles.Any())
{
return true;
}
}
return false;
}
}
It is a cryptic message for a well-known EF restriction: you can’t use reference types in
Contains. In stead do this:
