作者：
这篇文章主要介绍了c#操作excel的示例，里面的方法可以直接导出数据到excel，大家参考使用吧
复制代码 代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Office.Interop.Excel;
using System.Reflection;
namespace ListToExcel
{
class Program
{
static List<objtype> objs = new List<objtype>();
static void Main(string[] args)
{
objs.Add(new objtype() { name = "allen", val = "aaa" });
objs.Add(new objtype() { name = "allen", val = "aaa" });
objs.Add(new objtype() { name = "allen", val = "aaa" });
objs.Add(new objtype() { name = "allen", val = "aaa" });
objs.Add(new objtype() { name = "allen", val = "aaa" });
objs.Add(new objtype() { name = "allen", val = "aaa" });
objs.Add(new objtype() { name = "allen", val = "aaa" });
objs.Add(new objtype() { name = "allen", val = "aaa" });
objs.Add(new objtype() { name = "allen", val = "aaa" });
objs.Add(new objtype() { name = "allen", val = "aaa" });
objs.Add(new objtype() { name = "allen", val = "aaa" });
objs.Add(new objtype() { name = "allen", val = "aaa" });
ExportDataToExcel("", "", @"c:\a.xls", "a");
}

try
{
int n = 0;
for (int i = 1; i < objs.Count; i++)
{
var excelRange = (Range)ws.Cells[i, 1];
excelRange.Value2 = objs[i].val;//Value2?
excelRange = null;
}
}
catch (Exception ex)
{
string str = ex.Message;
}
finally
{
wb.Saved = true;
wb.SaveCopyAs(fileName);//保存
app.Quit();//关闭进程
}
}
}

}
