- 6/27/2022
This application will convert C# to VB while trying to preserve comments, formatting and as many Directives as possible. It converts the True side of conditional directives, the False side is not converted. After conversion it tries to compile the code. If a file can't be compiled it can be add to an ignore list so you can continue to process other files.
You can convert text by typing or pasting in into the left Window, a file, project or folder from the menu's.
The Tests under "TestCompile" are designed to translate the C# code in Roslyn and uses GetRoslynRootDirectory to find it. Results of folder conversion are stored in with the same directory structure with the root directory renamed to _VB. The original directories are unchanged.
This version required at least Visual Studio 2019 version 16.3.0 to compile the code it produces because it uses the new Visual Basic feature _ ' Comment to preserve most comments and formatting. To build the converter application, Visual Studio 2019 Version 16.11.9 or Visual Studio 2022 and .Net Core 6.0
Opening the resulting Visual Basic files in Visual Studio will further improve the formatting.
The last five files compiled are saved in an MRU list and you can save the edited Source windows into a Snippet and reload it. This is useful when you are debugging and want to focus on the lines that are a problem. You can search Input or Output buffers and hide the search options by clicking on the X. You can stop folder conversion with the Stop button. You can restart from where you left off by selecting the option "Start Conversion from last file" or start at the beginning by deselecting this option, if this version is selected and you switch to convert a new folder the application will immediately return done and you will need to deselect the option. You can show or hide line numbers from the View Menu.
Work to be done: There are several Stop statements for debugging, and if you continue past them reasonable things will happen but a better translation is possible.
https://dotnetfeed.blob.core.windows.net/dotnet-core/index.json is added to NuGet Package Source to find Microsoft.Dotnet.XUnitExtensions which provides ConditionalFact and PlatformSpecific attributes used for testing.
Any changes to CSharpToVB application needs to change the version information in the project file AND in MyProject/AssemblyInfo.vb until Visual Studio is able to general file automatically for a WinForms application.
