This free online converter lets you convert code from VB.NET to Kotlin in a click of a button. To use this converter, take the following steps -

  1. Type or paste your VB.NET code in the input box.
  2. Click the convert button.
  3. The resulting Kotlin code from the conversion will be displayed in the output box.

Examples

The following are examples of code conversion from VB.NET to Kotlin using this converter. Note that you may not always get the same code since it is generated by an AI language model which is not 100% deterministic and gets updated from time to time.

Key differences between VB.NET and Kotlin

CharacteristicVB.NETKotlin
SyntaxVB.NET uses a syntax similar to the BASIC programming language, with keywords such as 'If', 'For', and 'While'. It also supports the use of 'Option Strict' to enforce type checking.Kotlin has a modern and concise syntax, influenced by languages like Java and Scala. It uses keywords such as 'if', 'for', and 'while', and supports features like null safety and extension functions.
ParadigmVB.NET is primarily an object-oriented programming language, but it also supports procedural and functional programming paradigms.Kotlin is a statically-typed programming language that supports both object-oriented and functional programming paradigms. It encourages immutability and provides features like higher-order functions and lambda expressions.
TypingVB.NET is a statically-typed language, which means that variable types are checked at compile-time.Kotlin is also a statically-typed language, but it provides type inference, allowing developers to omit explicit type declarations in many cases.
PerformanceVB.NET is compiled to Intermediate Language (IL) code, which is then executed by the .NET runtime. It offers good performance, but it may not be as fast as languages like C++ or Rust.Kotlin is compiled to Java bytecode, which can be executed by the Java Virtual Machine (JVM). It has similar performance characteristics to Java.
Libraries and frameworksVB.NET has access to the extensive .NET Framework, which provides a wide range of libraries and frameworks for various purposes, including web development, database access, and GUI development.Kotlin can leverage the existing Java libraries and frameworks, as it is fully interoperable with Java. It also has its own ecosystem of libraries and frameworks, such as Ktor for web development and Room for database access.
Community and supportVB.NET has a smaller community compared to languages like C# or Java. However, it still has active support from Microsoft and a dedicated user base.Kotlin has gained popularity in recent years and has a growing community. It is officially supported by JetBrains, the company behind IntelliJ IDEA, and has good integration with the Android development ecosystem.
Learning curveVB.NET has a relatively low learning curve, especially for developers familiar with BASIC or other .NET languages like C#. It has a more verbose syntax compared to Kotlin.Kotlin has a moderate learning curve. It is designed to be easy to learn for Java developers, as it shares many similarities with Java. It has a more concise syntax compared to VB.NET.
