c# parallel implementation example

Updated: January 3, 2024 11:08:33 Author: wangyue4

This article mainly introduces the implementation example of c# parallelism. We use the method and combine it to improve the reading speed. It has certain reference value. If you are interested, you can learn about it.

The following is an example of using C# parallel processing to read a large number of small files. In this example, we useMethods and combinationTo improve the reading speed:

using System;
using ;
using ;
using ;

class Program
{
    static void Main(string[] args)
    {
        string directoryPath = @"path_to_your_directory";
        string searchPattern = "*.txt"; // Or other file extension that meets your needs
        // Get all small files that match the pattern in the specified directory        string[] files = (directoryPath, searchPattern);

        ConcurrentBag&lt;string[]&gt; allLines = new ConcurrentBag&lt;string[]&gt;();

        // Use parallel processing to read all files        (files, file =&gt;
        {
            // Read the entire file at once            string[] lines = (file);
            (lines);
        });

        // Merge and process all rows        string[] allFileContents = (lines =&gt; lines).ToArray();

        // Process all file contents here        foreach (string line in allFileContents)
        {
            // Process each line here        }
    }
}

In this example:

We first get all the specific modes in the specified directory (for example.txtfile with extension).
useMethods read the contents of each file in parallel. This utilizes a multi-core processor to read multiple files simultaneously, thereby increasing speed.
Add the contents of each file to theConcurrentBagmiddle.ConcurrentBagIt is a thread-safe data structure suitable for use in multi-threaded environments.
useSelectManyMethods will contain multiple arrays of stringsConcurrentBagMerge into a single array of strings so that all files can be processed in a loop.

Note that this example assumes that your system and hardware can support parallel processing and have a moderate file size and can be read into memory at one time. In practical applications, you may need to adjust according to specific needs and environment.

This is the end of this article about the implementation example of c# parallelism. For more related c# parallelism, please search for my previous articles or continue browsing the related articles below. I hope everyone will support me in the future!
