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},
	};
	sheet.Cells["A1"].LoadFromCollection(data);
	sheet.Cells["A1"].SetHeaders("Name", "Value");
	package.SaveAs(new FileInfo(@""));
}

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.

EPPlus Excel addresses are not zero based: The first column is column 1!

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
