Top 5 Errors In C# That You Need To Know About Them

Mar 23, 2023 | Web Design | 0 comments

Today, the C# programming language is one of the IT industry’s most powerful, rapidly developing, and in-demand languages.

Now, a wide variety of applications is written on it: from small desktop programs to large web portals and web services that serve millions of users every day.

C# is no longer a young language, and like the rest of the .NET platform, it has come a long way. The first version of the language came out with the Microsoft Visual Studio .NET release in February 2002. The current version of the language is C# 11, which was released on November 8, 2022, along with the release of .NET 7. If you suffer from tons of C# assignments at college, it is a wise decision to seek help at https://cwassignments.com/

C# is a language with a C-like syntax and is similar to C++ and Java. Therefore, if you are familiar with one of these languages, then mastering C# will be easier.

For example, C# supports polymorphism, inheritance, operator overloading, and static typing. The object-oriented approach allows us to solve the problems of building large but, at the same time, flexible, scalable, and extensible applications. In addition, C# continues to develop actively, and with each new version, more and more interesting functionalities appear. 

Errors Classification 

Errors in the program are things that you can never avoid. Even skilled programmers write with errors, but they know how to solve problems, and that is the main characteristic of a well-skilled developer. There can be minor errors that do not affect the application run, for example, output text mistakes. And from the other side, errors can be fatal, which makes the application crash; help here.

There are 3 main types of errors syntax, runtime, and logical.

Syntax Errors 

Syntax errors are fatal errors that prevent program compilation. At the same time, syntax errors are simple errors that can be found fast. Usually, programmers know several programming languages, and that leads to using other programming language commands in C# code. In addition, C# is a case-sensitive language, so using capitals will be a syntax error. Do not mix up orthographical text mistakes for the output product interface. Syntax errors represent only by syntax mistakes in code writing. 

Runtime Errors 

Runtime errors are also called exceptions. These types of errors take place during the execution of the program. To find the runtime errors, you should use the method which is called exception handling. It is working on a prediction theory. The C# has been developed enough and has a database of cases with the most common errors, which take place and can be solved at the stage of the software creation. C# has built-in exception classes for different possible errors. For example, if your program is going to divide the value by zero.  However, in case you are creating some specific software with unique rules, you should create a custom exception class.

Let us have a look at the ‘Try-Catch-Finally’ block that is used for excepting handling. With its help of it, you can find the part of the code where you have the error, and you can correct it.

When you run the program in debugging mode, special character information about the application is created. It helps Visual Studio to find out what is happening after every code line. This information helps you to transfer debugging information to the Visual Studio system, check and edit the variable value, pausing of the application run, automatically stop the program at a given point, a program run one line at a time, change variable data, and start selected functions. All these are required to add proper changes in the code with the error. These methods are divided into two types. You can stop the program in the place where the error is taking place, or you can run it to the end and save all the information in the logged files. 

Logical Errors 

Logical errors are happening even when the code was written correctly, but the actual result is different from the expected result. It is very difficult to find them because you should run the ready-made product, make special tests, and know the technical characteristics of the desired product. For example, the application cannot add the data to the database because one of the fields is missing, or you can add invalid data in a field that should not accept this type of data. 

Very often, you can find logical errors only after quality assurance tests or user feedback that something is working in the wrong way. As a result, you will need to do program tracing to find out the issue and how it should work expectedly. For this purpose, the ideal solution will be Visual studio; it has vast options of instruments for this.

Some errors can be found only after code compilation. You will get the error code, which is unique for different types of errors. You can use references to find the error’s name and a solution how to solve it. 

Errors that are found in ready-made IT products are called bugs. When your product is ready, the quality assurance team checks it for errors. They add all of them to the bug-tracking system. When all the bugs are known and systemized, the project manager sets the priority for them. It shows which bugs should be removed faster and which ones can wait.

One of the bugs’ priority gradation options is high, medium, and low. If the bug has a high priority, that means that the error must be corrected as soon as possible because its presence is critical for the project. The medium priority means that the bug must be corrected; its existence is not critical but requires a mandatory solution. And the low priority means that the error must be corrected, its presence is not critical, and it does not require urgent elimination. According to their priority, the high-priority bugs should be eliminated asap, and the last ones are low-priority bugs. 

Conclusion

C# is one of the most popular programming languages. But as every language is dependent on humans, it is not possible to avoid errors. Don’t worry if you face any of them because it is not something fatal. Luckily, you can find help online and cope with the problem fast.
