Inline arrays enable you to create an array of fixed size in a struct type. Such a struct, with an inline buffer, should provide performance comparable to an unsafe fixed size buffer. Inline arrays are mosly to be used by the runtime team and some library authors to improve performance in certain scenarios. You likely…
C# 12 introduces a new simplified syntax for creating arrays. It looks like this: It’s important to note that the array type needs to be specified explicitly, so you cannot use var for declaring the variable. Similarly, if you wanted to create a Span<int>, you can do: Multi-dimensional arrays The advantages of this terse syntax…
dotnet script enables you to run C# scripts (.CSX) from the .NET CLI. The only requirement is to have .NET 6 or newer installed on your machine. You can use the following command to install dotnet-script globally: Then to execute a script file you simply call dotnet script <file_path> like in the example below: How…
This can be fixed in two simple steps:
The most likely cause of this error is an update to Flutter (flutter upgrade) which led to some imcompatibility with your existing code or your project’s dependencies. The Theme.of(context).accentColor property has been deprecated since Flutter 1.17 and is entirely removed from the current version, thus the error your are seeing. What to use instead Or, if…
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 megabyte is a unit of digital information, denoted by the symbol MB. In the International System of Units (SI), the prefix “mega” represents a multiplier of 1,000,000 (10^6). Hence, one megabyte is equivalent to one million bytes of information, and this definition is now an integral part of the International System of Quantities. However,…
This is quite a frequent question. You’ve got: But what comes after quadrillion? The answer is: quintillion. A quintillion, has 18 zeroes. That’s a lot of zeroes: 1.000.000.000.000.000.000. But there’s more. If you look past the quintillion, you’ve got: Interested in how long it would take a PC to count to a trillion? Check out…
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…
.NET 8 introduces several new naming policies that can be used with the System.Text.Json serializer. To name them: Let’s look at the serialized output for each of them. For this, we’re going to use a Car class with the following definition: And we are going to serialize the following object instance: Lower snake case (snake_case)…
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…
With .NET 8 we are introduced to a new dictionary type which improves the performance of read operations. The catch: you are not allowed to make any changes to the keys and values once the collection is created. This type is particularly useful for collections that are populated on first use and then persisted for…
