News

3.4.2026: I realized today that my GetWords method was broken by a new ReadOnlySpan I tried to use (written by ChatGPT). The old way worked for 20 years, so I went back to that. Also some Microsoft NuGet packages were updated.

2.13.2026: I added a method to FileHelper - IsFileInUse.

11.21.2025: I updated this project to .NET 10.

11.12.2025: Version 9.1.6 - I added a new FontHelper class. This class makes it easy to search for installed fonts. This is used by a demo project I have coming up.

11.12.2025: Version 9.1.5 - I added a feature that can be used with PixelDatabase.NET to draw text on an image. The method SplitTextIntoLines was added, and this returns a List with the Text And Top set for each image.

11.12.2025: Version 9.1.3 - I added a new property Top to the TextLine object (int). This property is used by PixelDatabase.NET to convert text into lines of text, and the images are drawn to a certain place on the image

7.31.2025: Version 9.1.2 - added anew method to FolderHelper called IsFolderEmpty This method returns true if the folder is empty.

public static bool IsFolderEmpty(string folderPath) { // Initial Value bool isEmpty = false; // If the directory exists if (Directory.Exists(folderPath)) { // Get all files and subfolders string[] entries = Directory.GetFileSystemEntries(folderPath); // Set the return value isEmpty = (entries.Length == 0); } // Return value return isEmpty; }

7.11.2025: I added a new method FolderHelper.GetFolders()

// Gets the folders as a List<string> List<string> folders = FolderHelper.GetFolders(path);

2.23.2025: Added a new class called Morpheas

This class is used to determine if an object has changes.

// generate a hash string hash = Morpheas.Serialize(obj); // has this object changed bool hasChanges = Morpheas.Compare(obj, hash)';

I use to enable button for Save if an object has changes.

2.17.2025: I added a new method to FolderHelper Exists

bool Exists(string path);

1.22.2025: Added a new method to TextHelper

FindTextInQuotes(string input)

1.21.2025: Two new methods to TextHelper:

ReplaceTextInFile(string fileName, string textToFind, string replacementText) ReplaceTextInFile(string fileName, List<Replacement> replacements

A Replacement is just a class with two properties: SearchText and ReplacementValue

11.12.2024: I updated the project to .NET 9.

9.2.2024: I fixed a bug with GetTextLines in case the text just has \r, instead of \r\n for new lines.

8.14.2024: I changed NumericHelper.RoundDown and RoundUp to now take into account digits.

1.16.2024: The description was wrong for this project. I had forgot to change the description to, This project has been updated to .NET 8.

12.14.2023: I added a new method CloneLines to TextHelper. This method create a new List of TextLine objects, and copies the text from the source parameter. This is used by DataJuggler.RandomUSD.

11.20.2023: Added a new method to TextHelper - ExportWords. I also added a new property Index to Word and TextLine objects, and set the value for Index when GetWords and GetTextLines is called.

11.14.2023: This project has been updated to .NET 8.

8.29.2023: I added a new method to NumericHelper - DivideDoublesAsDecimals. .NET does not handle division by doubles very well, so this method casts the doubles given to decimals, and returns the quotient as a double.

8.13.2023 - Added a new method to TextHelper - GetTextLinesFromFile. I also modified the method GetTextLines, to have an option to parse the words foreach line. The new method GetTextLinesFromFile reads the text from the file, and then calls GetTextLines with optional parameters to also get the words and pass in your own delimiter. I also added an icon (png) for the project.

8.11.2023 - Added a new method to DateHelper - ParseEightDigitDate.

Blazor Excelerate

Code Generate C# Classes From Excel Header Rows

Live Site https://excelerate.datajuggler.com

Code: https://github.com/DataJuggler/Blazor.Excelerate

Blazor Excelerate uses Nuget package DataJuggler.Excelerate, which allows you to load and save entire worksheets and workbooks with a few lines of code.

List of classes:

BooleanHelper

Parses booleans and allows you set to a default value.

CodeHelper

Used in formatting code. An example of this is in the live site https://codopy.com, which is an opensource project here: https://github.com/DataJuggler/Codopy Format C# Code From Visual Studio when pasting to Git Hub read me files, or the social media.

CodeLine

A code line is a line of C# code. This class is used in conjunction with TextLine.cs and CodeHelper.cs

ConfigurationHelper

This class reads app settings from an app.config or web.config. This was created for .NET Framework, but still works.

DateHelper

This class has methods to help parse dates safely.

EnumHelper

This class make it easier to parse and iterate enumerations.

EnvironmentVariableHelper

This class makes it simple to get and set values for System, User or Process Environment Variables.

FileHelper

This class has many method that help with dealing with files, such as get all files recursively from a folder, create a file name with a partial guid to ensure uniqueness in a folder and more.

ListHelper

This class is a must for anyone who deals with Lists or List. My two favorite methods are HasOneOrMoreItems and HasXOrMoreItems.

NullHelper

Check if multiple objects at once with NullHelper.Exists(object1, object2, object3, object4, object5);

NumericHelper

This class started as a way to parse int's, double's and decimal's, however it has evolved since and has many helpful methods such as EnsureInRange and IsInRange and more.

TextHelper

This is one of my favorite classes. TextHelper.Exists(string1, string2, string3, string4) is much easier to write than if ((!String.IsNullOrEmpty(string1)) && ((!String.IsNullOrEmpty(string2)) && (!String.IsNullOrEmpty(string3)) && (!String.IsNullOrEmpty(string4))). Also there are methods such as CapitalizeFirstChar, GetTextLines, GetWords, StartsWithVowel, and more.

XmlPatternHelper

This class is used to encode and decode xml text if the file contains ampersands (&) or greater than or less than signs.

This class is used by Regionizer and Regionizer2022 Visual Studio Extensions, where the custom comment dictionary has to be able to save < > and &'s in Xml.
