c# - "There is no editor available for" Can't open .cs

Question

My computer shut down while working on a project and when I opened C# again and recovered it, I got an error saying

There is no editor available 'for filename.cs'
Make sure the application for the file type (.cs) is installed

And now I can't access my code at all.

I'm using Visual C# 2010 express.

I tried opening it directly and it brings up C# but the .cs file opens up in notepad. The file size is 30kb so it didn't get deleted. And there is still a working .exe in the debug folder of the last run. Is there any way to recover the code?

Answer 1

To fix the problem you need:

1. NotePad++

And you should follow this simple steps:

1. Close Visual Studio.

2. Go to the Backup Folder of your VS version usually in: "C:Users(your user name)DocumentsVisual Studio (year)Backup Filesyour project or application name".

3. Open the last Backup file of your corrupted file, usually the name format is : "Recovered-month.-day-year-time.(Your File Name).cs" with NotePad++, and copy the source code.

4. Go to your corrupted file in the project folder and open it with NotePad++, Edit => Select All => Past the source code and Save.

5. Go to windows start list and search for: "Visual Studio Tools" folder, open it and double click on: "Developer Command Prompt for VS(year)".

6. Write this two codes in the Developer Command Prompt: "devenv.exe /setup" and then "devenv /resetskippkgs" .

7. Open your project.

Note: if this didn't work for you try to do the steps before in this arrangement:

1) => 2) => 3) => 4) => 7) => 1) => 5) => 6) => 7)

and your problem will be fixed.

It works 100% for me, i hope this will helps you!
