C# Constraints in Generic

January 24, 2021
C#

The easiest way to remember C# Constraints is to write them down
For example having two generic parameters with different Constraints will be written like this:

1
2
3
4
5
6
7
8
9
10
11
12
13
public class SqlRepository<T, T2>
: IRepository<T> where T : class, IEntity
                 where T2 : struct
{
    DbContext _ctx;
    DbSet<T> _set;

    public SqlRepository(DbContext ctx)
    {
        _ctx = ctx;
        _set = _ctx.Set<T>();
    }
}
