未能找到路径“F:\批量导入\upfiles\20100825024205新建 Microsoft Excel 工作表.xls”的一部分
ASP.NET想把excel导入到SQL数据库，在excel保存到服务器这一部出问题了，是在本机上测试的。后台代码如下：
using System;

using System.Configuration;

public partial class _Default : System.Web.UI.Page
{
string strConn = "server=.;user id=sa;pwd=;DataBase=master"; //链接SQL数据库
protected void Page_Load(object sender, EventArgs e)
{
SqlConnection cn = new SqlConnection(strConn);
cn.Open();
SqlDataAdapter sda = new SqlDataAdapter("select * from hhaspx_gz", cn);
DataSet ds = new DataSet();
sda.Fill(ds, "hhaspx_gz");
this.GridView1.DataSource = ds.Tables["hhaspx_gz"];
this.GridView1.DataKeyNames = new string[] { "hhaspx_id" };
this.GridView1.DataBind();
}
/**/

public DataSet ExecleDs(string filenameurl, string table)
{
string strConn = "Provider=Microsoft.Jet.OleDb.4.0;" + "data source=" + filenameurl + ";Extended Properties='Excel 8.0; HDR=YES; IMEX=1'";
OleDbConnection conn = new OleDbConnection(strConn);
conn.Open();
DataSet ds = new DataSet();
OleDbDataAdapter odda = new OleDbDataAdapter("select * from [Sheet1$]", conn);
odda.Fill(ds, table);
return ds;
}
protected void Button1_Click(object sender, EventArgs e)
{
if (FileUpload1.HasFile == false)//HasFile用来检查FileUpload是否有指定文件
{
Response.Write("<script>alert('请您选择Excel文件')</script> ");
return;//当无文件时,返回
}
string IsXls = System.IO.Path.GetExtension(FileUpload1.FileName).ToString().ToLower();//System.IO.Path.GetExtension获得文件的扩展名
if (IsXls != ".xls")
{
Response.Write("<script>alert('只可以选择Excel文件')</script>");
return;//当选择的不是Excel文件时,返回
}
SqlConnection cn = new SqlConnection(strConn);
cn.Open();
string filename = DateTime.Now.ToString("yyyyMMddhhmmss") + FileUpload1.FileName; //获取Execle文件名 DateTime日期函数
string savePath = Server.MapPath("~\\upfiles\") + filename;//Server.MapPath 获得虚拟服务器相对路径
FileUpload1.SaveAs(savePath); //SaveAs 将上传的文件内容保存在服务器上
DataSet ds = ExecleDs(savePath, filename); //调用自定义方法
DataRow[] dr = ds.Tables[0].Select(); //定义一个DataRow数组
int rowsnum = ds.Tables[0].Rows.Count;
if (rowsnum == 0)
{
Response.Write("<script>alert('Excel表为空表,无数据!')</script>"); //当Excel表为空时,对用户进行提示
}
else
{
for (int i = 0; i < dr.Length; i++)
{
string hhaspx_rq = dr[i]["日期"].ToString();//日期 excel列名【名称不能变,否则就会出错】
string hhaspx_bh = dr[i]["编号"].ToString();//编号 列名 以下类似
string hhaspx_xm = dr[i]["姓名"].ToString();
string hhaspx_dx = dr[i]["底薪"].ToString();
string hhaspx_kh = dr[i]["考核"].ToString();
string hhaspx_jl = dr[i]["奖励"].ToString();
string hhaspx_jt = dr[i]["津贴"].ToString();
string hhaspx_jb = dr[i]["加班"].ToString();
string hhaspx_zb = dr[i]["值班"].ToString();
string hhaspx_jx = dr[i]["绩效"].ToString();
string hhaspx_hj = dr[i]["合计"].ToString();
string sqlcheck = "select count(*) from hhaspx_gz where hhaspx_rq='" + hhaspx_rq + "'And hhaspx_xm='" + hhaspx_xm + "'"; //检查用户是否存在
SqlCommand sqlcmd = new SqlCommand(sqlcheck, cn);
int count = Convert.ToInt32(sqlcmd.ExecuteScalar());
if (count < 1)
{
string insertstr = "insert into hhaspx_gz (hhaspx_rq,hhaspx_bh,hhaspx_xm,hhaspx_dx,hhaspx_kh,hhaspx_jl,hhaspx_jt,hhaspx_jb,hhaspx_zb,hhaspx_jx,hhaspx_hj) values('" + hhaspx_rq + "','" + hhaspx_bh + "','" + hhaspx_xm + "','" + hhaspx_dx + "','" + hhaspx_kh + "','" + hhaspx_jl + "','" + hhaspx_jt + "','" + hhaspx_jb + "','" + hhaspx_zb + "','" + hhaspx_jx + "','" + hhaspx_hj + "')";
SqlCommand cmd = new SqlCommand(insertstr, cn);
try
{
cmd.ExecuteNonQuery();
}
catch (MembershipCreateUserException ex) //捕捉异常
{
Response.Write("<script>alert('导入内容:" + ex.Message + "')</script>");
}
}
else
{
Response.Write("<script>alert('内容重复！禁止导入');location='default.aspx'</script></script> ");
continue;
}
}
Response.Write("<script>alert('Excle表导入成功!');location='default.aspx'</script>");
}
cn.Close();
}
}
错误提示：
行 64: string filename = DateTime.Now.ToString("yyyyMMddhhmmss") + FileUpload1.FileName; //获取Execle文件名 DateTime日期函数
行 65: string savePath = Server.MapPath("~\\upfiles\") + filename;//Server.MapPath 获得虚拟服务器相对路径
行 66: FileUpload1.SaveAs(savePath); //SaveAs 将上传的文件内容保存在服务器上
行 67: DataSet ds = ExecleDs(savePath, filename); //调用自定义方法
行 68: DataRow[] dr = ds.Tables[0].Select(); //定义一个DataRow数组
[解决办法]
看看NETWORK SERVICE(2003下)或者aspnet(xp下)有对F:\批量导入\upfiles\的写权限没？
在文件夹属性的安全页中。
