IEnumerable objects

Exporting data to an Excel doesn’t get easier than this

using (var package = new ExcelPackage())
{
	var sheet = package.Workbook.Worksheets.Add("IEnumerable");
	var data = new[]
	{
		new {Name = "A", Value = 1},
		new {Name = "B", Value = 2},
		new {Name = "C", Value = 3},
	};
	bool generateHeaders = true;
	sheet.Cells["A1"].LoadFromCollection(data, generateHeaders);

	// Overwrite headers with something fancier
	sheet.Cells["A1"].SetHeaders("Name", "Value");
	package.SaveAs(new FileInfo(@""));
}

Comparing NSubstitute syntax with Moq, probably the most used mocking framework out there at the moment.

In case your users want to continue working with the Excels after generation.

Not a problem for EPPlus. Instead of calculating values and writing them to an excel, leverage the power of Excel formulas.

Version 4.5.3.3 is the last version of EPPlus you can use without a license for commercial use.

A listing of handy but less known shortcuts in Windows Explorer and some Autohotkey examples on how to add extra functionality.

Open Windows Explorer, the most direct way:

My PowerShell, Posh-Git and .gitconfig color configuration because of some red-green troubles with the default configurations.

A cheat sheet with everything there is to know about formatting the primitive types, DateTimes and TimeSpans in .NET.

A cheat sheet outlining the syntax differences between VB.NET and C#. This post is written specifically for advanced C# developers with little to no VB.NET knowledge who need to do some VB.NET coding.

Because some things are just so similar but still confusingly different in VB.NET vs C#…

Along the way we’ll make some amazing discoveries like:

• There are things VB.NET just can’t do (pointers, …)
• There are a few cases where VB.NET code is shorter than its C# counterpart (gasp!)
• VB.NET defaults are not what you might expect from a strongly typed language due to its VB6 legacy (Option Strict, Explicit)
• There is some VB.NET only stuff that comes in handy from time to time
