C# (pronounced see sharp, like the musical note ) is a general-purpose, multi-paradigm programming language encompassing strong typing, lexically scoped, declarative, imperative, functional, generic, object-oriented, and component-oriented programming disciplines. It was introduced in 2000 by Microsoft as part of its .NET initiative, and later approved as an international standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270:2018).
You can use the WaitForExit method to wait for the process to complete. Your code will wait synchronously for the process to finish, then it will resume execution. Let’s look at an example: The code above will start a new cmd.exe process, and execute the timeout 5 command. The process.WaitForExit() call will force your program…
The using alias directive has been relaxed in C# 12 to allow aliasing any sort of type, not just named types. This means that you can now alias tuples, pointers, array types, generic types, etc. So instead of using the full structural form of a tuple, you can now alias it with a short descriptive…
The With…End With statement in VB allows you to execute a series of statements that epeatedly refer to a single object. Thus the statements can use a simplified syntax for accesing members of the object. For example: Is there a C# syntax equivalent? No. There is not. The closest thing to it would be the…
Starting from C# 12, it is possible to define a primary constructor within classes and structs. The parameters are placed in parentheses right after the type name. The parameters of a primary constructor have a broad scope. They can be utilized to initialize properties or fields, serve as variables in methods or local functions, and…
C# is a modern, general-purpose, object-oriented programming language developed by Microsoft. It is widely used for Windows desktop applications, games (especially using the Unity engine), and web development through the ASP.NET framework. C# is considered to be beginner-friendly and is a great language for new programmers. Below we explore some of the reasons why C#…
As technology continues to evolve, so does the C# programming language. With the release of C# 12 on the horizon, developers can look forward to a host of exciting new features and enhancements that promise to streamline their coding experience and open up new possibilities in software development. If you haven’t yet switched to C#…
While trying out C# 12 features, it’s possible you might come across errors similar to these: Feature is not available in C# 11.0. Please use language version 12.0 or later. or Error CS8652: The feature ‘<feature name>’ is currently in Preview and unsupported. To use Preview features, use the ‘preview’ language version. There are two…
Starting with C# version 12, you can specify default values for your parameters in lambda expressions. The syntax and the restrictions on the default parameter values are the same as for methods and local functions. Let’s take an example: This lambda can now be consumed as follows: params array in lambda expressions You can also…
All right folks, generic attributes are finally a thing in C#! 🥳 You can define one just as you would define any other generic class: And use it like you would use any other attribute: Generic attribute restrictions When applying the attribute, all the generic type arguments must be provided. In other words, the generic…
The file modifier restricts a type’s scope and visibility to the file in which it is declared. This is especially useful in situations where you want to avoid name collisions among types – like in the case of generated types using source generators. A quick example: In terms of restrictions we have the following: On…
C# 11 introduces the concept of raw string literals to the language and with that come a set of new features for string interpolation as well. First of all, you can continue to use the interpolation syntax as you know it in combination with raw string literals like this: The output will be: Escaping braces…
Raw string literals are a new format which enables you to include whitespace, new lines, embedded quotes, and other special characters in your string, without requiring escape sequences. How does it work: A quick example: This will output the following: Whitespace before the closing sequence The whitespace before the closing double-quotes controls the whitespace which…
