Using Stored Procedures and Parameters.AddWithValue, Page 3
The code is pretty basic. Call GetCode with the stored procedure name and a connection string. The code reads INFORMATION_SCHEMA.PARAMETERS and fills in the ADO.NET AddWithValue calls in the template string. The results are returned and copied to the clipboard for convenience.
Regex.Unescape is used to take into account the \t (tab) and \r\n (carriage return newlines) for pagination purposes, and the Log property can be assigned Console.Out to display the output of the class—that is, tell you what the class is doing.
With a little extra work, you could add parameter directions, data types, and lengths and take into account elements such as readers, adapters, and DataSets. I hope you have fun playing with the code.
From Alice in Wonderland, Lewis Carroll wrote "Begin at the beginning and go on till you come to the end; then stop." Everyone is at different phases of their programming journey. I hope some basic ADO.NET code helps those new to ADO.NET and that the Tip and sample at the end gave the rest of you a reason to read, too. Thanks for playing.
