.NET Academy Ideas

I suggest you...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

Enter your idea and we'll search to see if someone has already suggested it.

  1. Proof Read

    Proof read the content. Numerous typos in the content bring the quality of this site down. Which is a shame because it is a cool concept.

    • Writing to a file with using

      It can't even find the damn file.

      Instructions:

      Write to the local file Actors.txt

      Create a file stream called file with a using statement.
      Create a stream writer called writer using the file stram. This block must not use block syntax { ... } and instead by nested as the single statement under the previous using.
      Write each item in the list actors to the file on a new line. Use a foreach loop for this.

      Code:

      using (var file = new FileStream(@".\Actors.txt", FileMode.Open));

      Error: Run-time exception (line -1): Could not find file 'C:\Resources\directory\ad7365bd64d5400298d02c7e04ef408c.DotNetFiddle.Web.LocalResources\Sandbox\42654742-f66b-4dad-a6ce-ccee853fa647\Actors.txt'.

      How the hell can it not…

      • Reading from a file with using...gives dumb error message

        Please explain to me how the following code could possibly get an error message:

        Here are the instructions:

        Read from the local file 'Movies.txt'

        Create a file stream caleld file with a using statement.
        Create a stream reader called reader using the file stream. This block must be nested using block syntax { ... }.
        While we are not at the end of the stream, create a local string declaration named movie and assign this the value of the next line from the file.
        Write each move to the Console using WriteLine.

        Here's the code:

        using System;
        using System.IO;

        public…

        • have a button to go to next tutorial

          At the end of one section/tutorial, there is a conclusion. You click that on the TOC bar and you can give stars for how good tutorial was. But there is no next button, to go to the next tutorial in line. You have to go to the home page for .net academy, then back into c# and then scroll down to choose next in list. Why is there no next(tutorial/lesson)?

            • check instructions vs validator

              I have run into numerous issues validating, where the name of the object or the requested exercise conflicts with the validator. eg. Collections 4.1 asks for a dictionary to be created, but when you validate a new dictionary, the error says we need to create a list. It might be good to go through exercises and make sure the instructions match the validator.
