How to Set Cell Background Patterns and Color in Excel

In this tutorial, we explore setting cell background patterns and colors in Excel using the IronXL and Iron Software Drawing Library. After installing the required packages via NuGet, we dive into the code, where the namespaces IronXL and IronXL.Styles are included for Excel manipulation. Aliasing IronSoftware.Drawing as DoColor helps in clarity. We create a new workbook and set background fill patterns for cells A1 and A2. Cell A1 features alternating bars with an aquamarine color, while cell A2 displays thick vertical bands in a color defined by the hex code #AF2F. The workbook is saved as 'set_background_pattern.xlsx'. Running the project shows the successful application of these styles. The tutorial concludes by encouraging viewers to try out the software and explore its capabilities further with a trial subscription link provided.
