采纳反射完成后期绑定设置EXCEL的容易代码(建议加入精华区)

除了采用TblImp导入Excel object库实现Excel的调用外.
其实还可以采用反射的方法获得属性,并进行后期绑定实现
Excel的调用.下面是简单的调用EXCEL程序.

using System;
using System.Reflection;
using System.Windows;
using System.Windows.Forms;

class TestLateBound:System.Windows.Forms.Form
{
private Button myButton;
publicTestLateBound()
{
myButton=new Button();
myButton.Text="调用EXCEL";
myButton.Location=new System.Drawing.Point(100,100);
myButton.Click+=new System.EventHandler(TestBound);

this.Controls.Add(myButton);
this.Text="测试后期绑定 Excel Application";

}

public void TestBound(object sender,System.EventArgs ef)
{
Type myExcel;
myExcel=Type.GetTypeFromProgID("Excel.Application"); 

object objExcel;
objExcel=Activator.CreateInstance(myExcel);

object[] param=new object[1];
param[0]=true;
try
{
myExcel.InvokeMember("Visible",BindingFlags.SetProperty,null,objExcel,param);//和VC++中差不多,需要将参数封装为数组传入
}
catch (Exception e)
{
MessageBox.Show (e.ToString());
}

}
public static void Main()
{
Application.Run(new TestLateBound());
}
}
