Code It Any Way You Want: Performance Difference Between Static and Non-Static Methods

The article explores the performance disparity between static and non-static methods, commonly recommended for efficiency by code analysis tools.

Collection Performance: Looping Over a Collection Using Span and ReadOnlySpan

The article explores the performance benefits of utilizing Span and ReadOnlySpan for collection processing, highlighting advantages such as improved performance, reduced memory pressure, enhanced safety, and compatibility with modern API design. Span allows read-write access and efficient iteration with lightweight storage, while ReadOnlySpan provides read-only access to prevent accidental modifications, offering similar benefits for collection processing.

Code It Any Way You Want: Performance Considerations for Sealed and Internal Classes

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.

Collection Performance: Optimizing Sequence Comparison

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.

General Performance Tip: Type Conversion

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.

Reference Type & Structure Performance: Constant vs. Read-only Property

This content discusses the performance of using a constant vs. a read-only property.

String Performance: Checking for a Character

The article compares two methods of checking for the presence of a specific character in a string in C#. Benchmark results reveal that using a character in the search is 3.57 times more efficient than using a string, and Contains() outperforms StringComparison.Ordinal and StringComparison.OrdinalIgnoreCase in terms of speed.

dotNetDave Rocks The Austin .NET User Group (2024)

The dotNetDave No Rest for the Wicked World Tour is coming to the Austin .NET User Group in Texas on May 9th. This session will focus on code and app performance for Microsoft .NET, covering efficient code execution and techniques for minimizing memory footprint. Watch the live session and access related resources to optimize code performance.

Code It Any Way You Want: Constants vs. Read-only Fields

The article discusses best practices for checking strings for null in coding. It outlines three common methods: using == null, is null, or string.IsNullOrEmpty().

Collection Performance: Leveraging LINQ MAXBy() and MINBy() for Efficient and Readable Code

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.
