The article explores the performance implications of using LINQ for collection queries, finding that a conventional foreach() loop outperforms LINQ by 1.75 times in identifying items matching a given query. The conclusion suggests benchmarking to determine the optimal approach based on the nature of the query and elements being sought.
The post discusses alternative approaches to adding items to a collection using For() or ForEach() from the Task Parallel Library.
Modern best practices in method design emphasize returning empty collections instead of null values when no items are found, enhancing code safety and clarity.
The post discusses two methods for searching a specific key in a Dictionary. The ContainsKey() method is recommended by Microsoft for improved performance but is it more performant?
The post demonstrates the usage of Parallel.ForEachAsync() with a List of reference types.
LINQ's SequenceEqual() method compares two Byte arrays, returning a Boolean indicating equal length and matching elements. Access more on collection performance by subscribing.
The article introduces FastAny(), a method in the DotNetTips.Spargine.Extensions NuGet package designed to accelerate LINQ's Any() call, showcasing a 1.08 times performance improvement over the standard method. Notably, FastAny() not only enhances speed but also includes a built-in null check for the collection.
The ImmutableArrayExtensions contain a SequenceEqual() method for comparing ImmutableArray items. The method compares elements using the default equality comparer for TSource and can be used with a for() loop for performance validation.
The author delves into the performance disparities of using reference types, value types, and record types in collections.
Beginning with .NET 8, you have the option to employ the novel collection expression to generate frequently used collection values. A collection expression comprises a concise syntax, which, upon evaluation, can be assigned to a wide array of collection types. Key Features of Collection Expressions: Concise Syntax: Easily create collections using square brackets [] and comma-separated elements, such as … Continue reading Collection Expressions in .NET 8
