Language comparison
Key differences between VB.NET and C#
| Characteristic | VB.NET | C# |
|---|---|---|
| Syntax | VB.NET uses a syntax that is similar to the traditional Visual Basic language, with keywords such as 'Dim' for variable declaration and 'End If' for conditional statements. | C# uses a syntax that is similar to C and C++, with keywords such as 'int' for variable declaration and 'if' for conditional statements. |
| Paradigm | VB.NET supports both procedural and object-oriented programming paradigms. | C# supports both procedural and object-oriented programming paradigms. |
| Typing | VB.NET supports both static typing and dynamic typing. | C# supports only static typing. |
| Performance | VB.NET is generally considered to have slightly lower performance compared to C#. | C# is generally considered to have better performance compared to VB.NET. |
| Libraries and frameworks | VB.NET has access to the same libraries and frameworks as C# since they both target the .NET platform. | C# has access to a wide range of libraries and frameworks, including the .NET Framework and third-party libraries. |
| Community and support | VB.NET has a smaller community compared to C#, but still has active support and resources available. | C# has a larger and more active community, with extensive support and resources available. |
| Learning curve | VB.NET has a relatively gentle learning curve, especially for developers familiar with Visual Basic or other BASIC-like languages. | C# has a moderate learning curve, especially for developers familiar with C, C++, or Java. |
Common questions
Frequently Asked Questions
How do I convert VB.NET to C#?
Paste your VB.NET code into the input box, confirm the languages are set to VB.NET and C#, and click Convert. CodeConvert AI analyzes your VB.NET code and generates equivalent C# code in seconds, preserving the original logic and structure.
What are the main differences between VB.NET and C#?
VB.NET and C# differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each VB.NET construct to its closest C# equivalent. See the comparison table below for the key differences between VB.NET and C#.
Is the converted C# code accurate?
The AI produces high-quality C# code that preserves the behavior of your original VB.NET code and follows C# conventions. It handles common patterns, data structures, and idioms for both VB.NET and C#. For large or performance-critical code, review and test the C# output before using it in production.
Can I convert an entire VB.NET project to C#?
You can convert VB.NET files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from VB.NET to C#. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert C# back to VB.NET?
Yes. CodeConvert AI converts in both directions, so you can convert C# to VB.NET just as easily using our C# to VB.NET converter. Try the C# to VB.NET Converter
Is the VB.NET to C# converter free, and do I need to install anything?
Yes, it is free and runs in your browser with nothing to install and no IDE extension required. You can convert VB.NET to C# without an account for up to 2 conversions per day. Sign in for free for higher limits.
