Dapper is designed to be fast, efficient, and simple to use, which makes it a superb choice for developers who want to maximize efficiency and productivity.

As it is possible to see, there is nothing new with these two methods. We have a question and parameters, and we execute our statements Along with the ExecuteAsync approach.

I believe this method exists largely for earning easier to undertake Dapper in legacy codebases where as opposed to working with strongly typed lists you have to deal with a DataReader, and refactoring to utilize a typed listing it can be impossible. If that’s the situation, then is the strategy in your case. As being the title advise it just returns a IDataReader.

general public int CustomerID get; established; public string FirstName get; established; general public string LastName get; set; community string E-mail get; established;
