Can I map a result to Tuple in Dapper?

Question

I am trying to select a list of 2 integer columns map the results to a Tuple. Just as an example:

return connection.Query>(\"sele         


        

Answer 1

This works starting from C# 7. This is a Value Tuple

public (int Id, DateTime? PublishDate) GetItem(string id)
{
    const string sqlCommand = "select top 1 Id, PublishDate from Item where Id = @id";

    return _connection.Query<(int, DateTime?)>(sqlCommand, new { id }).FirstOrDefault();
}       

Using the method

var item = GetItem(123);
Console.WriteLine($"The publish date of item [{item.Id}] is [{item.PublishDate.Value}]");

Make sure you have installed Dapper 1.50.4 or later.
