Any events supported in ExcelDna?

Question

我想在Excel上初始化几个变量Dna .dll在Excel中加载？

Answer 1

Excel-DNA will check whether your add has a public class that implements the interface ExcelDna.Integration.IExcelAddIn , and if so will run the AutoOpen method when the add-in is loaded, and the AutoClose method if the user removes the add-in from the add-ins list.

So you'd have something like:

public class MyAddIn : IExcelAddIn
{
    public void AutoOpen()
    {
        // Do your initialization here...
    }

    public void AutoClose()
    {
    }
}
