In addition to using Tblimp to import Excel object libraries to implement Excel calls.
In fact, you can also use the method of reflection to obtain properties, and the implementation of late binding
An Excel call. The following is a simple call to the Excel program.

{
Private Button MyButton;
Public Testlatebound ()
{
Mybutton=new Button ();
mybutton.text= "Call Excel";
Mybutton.location=new System.Drawing.Point (100,100);
Mybutton.click+=new System.EventHandler (Testbound);

This. Controls.Add (MyButton);
This. text= "Test late bound Excel application";

}

public void Testbound (Object Sender,system.eventargs EF)
{
Type Myexcel;
Myexcel=type.gettypefromprogid ("Excel.Application");
