About This Tool

The VB to C# Converter targets developers migrating VB.NET codebases to C#. It accepts VB.NET snippets or larger files and outputs idiomatic C# code, preserving structure and intent. Conceptually, it relies on a multi-pass translation that first parses VB.NET, then applies mapping rules to convert declarations, control flow, and common API usage into C# equivalents. The resulting code is formatted for readability and maintainability. This tool is beneficial for teams updating legacy apps, libraries, or samples to align with modern .NET practices. It provides diagnostic information to highlight potential semantic differences and areas needing manual refinement. The converter includes configurable mappings, enabling teams to tailor translations for project conventions or API usage preferences, and to handle common patterns such as Dim declarations, For Each loops, Select Case, properties, and events. It also supports advanced mappings for generics, LINQ, and async/await when requested. Use cases include porting console applications, class libraries, or storefronts while maintaining a clear migration path and reducing time-to-compile.

How to Use

  1. Provide inputs: paste VB.NET source code into the tool input.
  2. Configure optional translation options if needed (e.g., enable advanced mappings).
  3. Run conversion to generate C# output.
  4. Review the converted_code and diagnostics, and adjust as necessary.
  5. Compile and test the translated project to validate behavior.

Frequently Asked Questions

Find Quick Answers

What can the converter translate?
The tool translates common VB.NET syntax including declarations, control flow constructs, properties, and typical API usage into C#. It does not cover VB6-era features or highly platform-specific code; complex scenarios may require manual refinement after translation.
What are the outputs?
The tool returns converted_code in C#, a diagnostics list describing any potential semantic differences or unsupported constructs, and a mapping_report detailing key decisions taken during translation for traceability.
What are the limitations?
It aims for syntactic and stylistic equivalence but does not guarantee full semantic equivalence. Highly dynamic VB code, late-bound APIs, or extensive VB-specific patterns may need manual verification and adjustments post-translation.
Is it free to use?
The converter is provided as a free online utility intended to assist code migration workflows; users should verify license terms in the hosting environment and note that automated translations may require post-processing.
