This article explores the historical belief that sealed and internal classes in .NET might offer performance advantages, but suggests that in modern .NET runtimes, compiler optimizations, and hardware advancements, the difference in performance is likely negligible, emphasizing that design considerations should drive decisions regarding class sealing or internalization rather than performance concerns.
The article discusses different methods for comparing two collections for identity in programming. It introduces the use of the SequenceEqual() method for comparing sequences in the LINQ extension methods, as well as the StructuralSequenceEqual() method, which is beneficial for comparing custom classes based on the values of their elements rather than object references.
This article explores type conversion in programming, comparing the traditional syntax with the newer "as" keyword in .NET. While the "as" keyword improves code readability, benchmark results suggest that the conventional method is slightly more performant, advising developers to stick with traditional type conversion unless significant performance improvements are observed with the "as" keyword.
This content discusses the performance of using a constant vs. a read-only property.
The article compares two methods of checking for the presence of a specific character in a string in C#.
The post discusses the importance of using constants for static numerical or string values in code, highlighting benefits such as clarity of intent. It provides an example of a read-only property for π and notes that .NET 10 benchmarks show similar performance for both methods. EditorConfig settings for identifying issues are also mentioned.
The article explores the usage of LINQ's MinBy() and MaxBy() methods, which efficiently return the objects with the minimum and maximum values in a sequence based on a specified key selector function.
