Folks, we’re gonna start a ‘cookbook’ of LINQ entries, which we’ll be building over time. This is just meant to be a series of solutions to specific scenarios, that the team comes across when writing code and using queries. I can’t think of a better way to communicate everything you might use LINQ for!<\/font><\/font><\/p>\n

<\/font> <\/p>\n

The point of the series is to show you the wide array of things LINQ can do. Like any good cookbook, we’ll have categories for the cookbook, so you can easily find items later. Don’t expect any particular ‘recipe’ to have a large description, although they will contain repro steps. Feel free to ask for any recipes you want to see, and we’ll get as many created as we can!<\/p>\n

<\/font><\/font><\/p>\n

o<\/font>   <\/span><\/span><\/span>My own personal favorites are two group boxes, with two labels in front on textboxes (and labels above the group boxes), and a couple of radio buttons in each. This ensures the recursive code is tested<\/font><\/font><\/p>\n

–<\/font>          <\/span><\/span><\/span>Add a button to the form and change the text of the button to ‘Go’. <\/font><\/font>Double-click the button, and modify the EventHandler code and add the method below:<\/p>\n
