  • Get the count of items in a GroupBy Linq-to-sql Query?

    - by Curtis White
    I have a groupby that I groups all elements. I can see the items are there in LinqPad but can't find a way to get the count. Here is what I have so far: SurveyResponses.Where( q = q.QuestionId == 4).GroupBy(q = q.AnswerNumeric).Where( g = g.Key == 1) In Linq Pad I can see there are 4 items in this query. If I do Count it returns 1. I've tried, ToList().Count, Select(x = x).Count, etc.

  • Length of current selection in Eclipse

    - by Grzegorz Oledzki
    Do you know any easy way to know what is the length of current selection in Eclipse? I.e. I select a line fragment and would like to know how many characters are there? Usually I count them manually, but that's stupid. When being desperate I move to the start, check the column number, move to the end, check the column number, subtract, think a minute if I should add 1 or not... and my selection is lost.

  • Enity framework not loading relationship even when using include

    - by dilbert789
    I have this code: Category selectedCategory = (from c in DB.Category.Include("SubCategory") join a in DB.Accessory on c.AccCatUID equals a.Category.AccCatUID where a.AccUID == currentAccessory.AccUID select c).FirstOrDefault(); It works fine, selectedCategory gets populated as expected. BUT selectedCategory has a child table 'SubCategory' which does not get loaded even though there is the include there. It is not loaded until I do this: selectedCategory.SubCategory.Load(); Why do I have to call load explicitly in order to load the child table?

    Is there a free or open source library to read Excel files (.xls) directly from a C# program? It does not need to be too fancy, just to select a worksheet and read the data as strings. So far, I've been using Export to Unicode text function of Excel, and parsing the resulting (tab-delimited) file, but I'd like to eliminate the manual step.

  • Date range intersection in SQL

    I have a table where each row has a start and stop date-time. These can be arbitrarily short or long spans. I want to query the sum duration of the intersection of all rows with two start and stop date-times. How can you do this in MySQL?
