想要操作wps或office表格需要引入相对应的dll,office好找,wps在扩展中找到kingsoft的一些dll.
其中通过特性描述来获取泛型的中文名.
具体实现代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Reflection;
using System.IO;
using ET;
using Microsoft.Office.Interop.Excel;
using System.Diagnostics;
using System.ComponentModel;
namespace src.Common

{
public static string Save<T>(List<T> list, string name, string saveWay, string tableHead)
{
try
{
SaveWPSExcel<T>(list, name, saveWay, tableHead);
return "WPS保存成功";
}
catch (Exception ex)
{
try
{
SaveOfficeExcel<T>(list, name, saveWay, tableHead);
return "office保存成功";
}
catch (Exception ex1)
{
return "请安装office或WPS";
}
}
}
