Code Example
There is an example console application that demonstrates basic usage of the .Net GAEB library on GitHub. The app shows the conversion between any GAEB formats and Excel as well as a simple iteration over all items from an imported GAEB file.
Additionally, you can view an article with example code that will guide you how to create custom GAEB files with the API. Here is additional information on how to use the libraries with Visual Studio.
Import any GAEB file with two lines of code:
public static Dangl.AVA.Project GetProject()
{
using (var gaebStream = File.OpenRead(@"C:\\OfferRequest.X83")
{
var gaebFile = GAEBReader.ReadGaeb(gaebStream);
return Converter.ConvertFromGaeb(gaebFile);
}
}
