ASP.NET中如何讲Excel表格中的数据导入到SQLServer中去？

不管你是那个数据库，将Excel里面的数据导入到数据库中的原理就是将Excel里面的数据存储到一个dataTable中，然后将数据一行一行添加到数据库的表里。
SqlConnection con = new SqlConnection(ConfigurationManager.AppSettings["aa"].ToString());
con.Open();//数据库连接字符串

DataTable dtXls = new DataTable();
if (this.fudAdd.PostedFile.FileName.ToString().Trim() != "" && this.fudAdd.PostedFile.FileName!=null)
{
string filePath = this.fudAdd.PostedFile.FileName.ToString().Trim();
FileInfo fileTag = new FileInfo(fudAdd.PostedFile.FileName);
string extendedName = fileTag.Extension;
if (extendedName.ToLower() != ".xls" && extendedName.ToLower() != ".xlsx")
{
Response.Write("");
return;
}
else
{
dtXls = ExcelToDataTable(filePath,extendedName);
if (dtXls==null||dtXls.Rows.Count <= 0 || dtXls.Columns[0].ToString() == "")
{
Response.Write("");
return;
}
else
{
if (dtXls.Columns[0].ToString() != "手机号码" || dtXls.Columns[1].ToString() != "状态")
{
Response.Write("");
return;
}
else
{
if (dtXls.Rows[0][0].ToString() == "")
{
Response.Write("");
return;
}
else
{
string result = AddXlsData(dtXls, con);
string[] resultData = result.Split('-');
string msg = "资料上传成功！共计" + resultData[0] + "条成功，" + resultData[1] + "条失败！";
Response.Write("");
logwrite.LogOpera(userid, "UnExistMobile_Mag.aspx", "UnExistMobile_Mag.aspx.cs", "成功上传一批空号");//记录log
BindData();
return;
}
}
}
}
con.Close();
