将Excel导入数据库
在Control 中：

}
//客户导入
[HttpPost]
public ActionResult ImportExcel(HttpPostedFileBase importxls)

//获取文件和扩展名
var fileName = Path.GetFileName(importxls.FileName);
//获取文件路径地址
var path = Path.Combine(Server.MapPath("~/App_Data/"), fileName);
//获取文件的扩展名
var exname = Path.GetExtension(importxls.FileName).ToLower();
try
{
if (exname == ".xls" || exname == ".xlsx")
{
importxls.SaveAs(path);
var connectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Path.Combine(Server.MapPath("~/App_Data/"), fileName) + ";Extended Properties=Excel 12.0;");
var adapterbvandrev = new OleDbDataAdapter("select*from[Sheet1$]", connectionString);
