What is the difference between vb.net and vb? vb.net adds many features of vb and evolves into a fully object-oriented programming language. The following article will compare vb.net and vb, and introduce the differences between vb.net and vb. I hope it will be helpful to everyone.
The difference between vb.net and vb
1. vb.net is a completely object-oriented programming language with abstraction and encapsulation , polymorphism, inheritance, overloading, interface shared member constructors and other features; while VB does not support inheritance.
2. Different error handling
In vb, there are only On Error....goto and On Errer Resume Next. These errors are called unstructured exception handling. The structured exception handling mechanism used in vb.net is try...catch....finally control. Its structure type is as follows:
try
'Code that may cause an exception
catch
'Code that handles exceptions when an exception occurs
Finally
'Clean up the scene
End try
Try statement block is used to throw exceptions. If an exception occurs, handle it in the Catch statement block. Finaly statement blocks are optional and are particularly useful when resources need to be released.
3. The forms generated by the two are different
VB.NET has two new form methods: Windows Forms and Web Forms. VB.NET allows the creation of different types of applications, for example, ASP.NET and ASP.NET Web service applications can be created, and also allows the creation of console applications and applications that run as desktop services.
Different from this, VB can only create Windows Forms.
4. There are differences in database access
vb6.0 implements database access through ADO (Active X Data Objext). vb.net accesses the database through ADO.NET 5. Differences in operation
VB.NET provides flexible reading and writing file functions, and multiple methods can be used to obtain the same result.
5. VB and VB.NET are also very different in control properties.

Community forums such as StackOverflow and Reddit, and 3. Open source projects on GitHub. These resources help developers improve their programming skills from basic learning to advanced applications.
The C# .NET Advantage: Features, Benefits, and Use CasesMay 05, 2025 am 12:01 AMThe advantages of C#.NET include: 1) Language features, such as asynchronous programming simplifies development; 2) Performance and reliability, improving efficiency through JIT compilation and garbage collection mechanisms; 3) Cross-platform support, .NETCore expands application scenarios; 4) A wide range of practical applications, with outstanding performance from the Web to desktop and game development.
Is C# Always Associated with .NET? Exploring AlternativesMay 04, 2025 am 12:06 AMC# is not always tied to .NET. 1) C# can run in the Mono runtime environment and is suitable for Linux and macOS. 2) In the Unity game engine, C# is used for scripting and does not rely on the .NET framework. 3) C# can also be used for embedded system development, such as .NETMicroFramework.
The .NET Ecosystem: C#'s Role and BeyondMay 03, 2025 am 12:04 AMC# plays a core role in the .NET ecosystem and is the preferred language for developers. 1) C# provides efficient and easy-to-use programming methods, combining the advantages of C, C and Java. 2) Execute through .NET runtime (CLR) to ensure efficient cross-platform operation. 3) C# supports basic to advanced usage, such as LINQ and asynchronous programming. 4) Optimization and best practices include using StringBuilder and asynchronous programming to improve performance and maintainability.
C# as a .NET Language: The Foundation of the EcosystemMay 02, 2025 am 12:01 AMC# is a programming language released by Microsoft in 2000, aiming to combine the power of C and the simplicity of Java. 1.C# is a type-safe, object-oriented programming language that supports encapsulation, inheritance and polymorphism. 2. The compilation process of C# converts the code into an intermediate language (IL), and then compiles it into machine code execution in the .NET runtime environment (CLR). 3. The basic usage of C# includes variable declarations, control flows and function definitions, while advanced usages cover asynchronous programming, LINQ and delegates, etc. 4. Common errors include type mismatch and null reference exceptions, which can be debugged through debugger, exception handling and logging. 5. Performance optimization suggestions include the use of LINQ, asynchronous programming, and improving code readability.
C# vs. .NET: Clarifying the Key Differences and SimilaritiesMay 01, 2025 am 12:12 AMC# is a programming language, while .NET is a software framework. 1.C# is developed by Microsoft and is suitable for multi-platform development. 2..NET provides class libraries and runtime environments, and supports multilingual. The two work together to build modern applications.
