无法打开或写入文件。该文件已由另一个用户独占打开，或者您需要查看和写入其数据的权限。'

Question

无法将我的excel文件保存在我在项目中创建的文件夹中...我想我在进行路径规范化时忘记了一些内容...也许我之后需要做些什么？ 我已经向用户授予权限之类的东西，我认为该文件未打开，我只有1个用户，并且没有打开。 这是代码专家：

protected void Upload_Click(object sender, EventArgs e)
    {
        string excelPath = Server.MapPath("~/Files/") + Path.GetFileName(FileUpload1.PostedFile.FileName);
        FileUpload1.SaveAs(excelPath);


        string filepath = Server.MapPath("~/Files/");
        string filename = Path.GetFileName(filepath);

        string ext = Path.GetExtension(filename);
        String strConnection = @"Data Source=PEDRO-PC\SQLEXPRESS;Initial Catalog=costumizado;Persist Security Info=True;User ID=sa;Password=1234";
        string excelConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + filepath + ";Extended Properties=\"Excel 12.0 Xml;HRD=YES;IMEX=1;\"";

        OleDbConnection excelConnection = new OleDbConnection(excelConnectionString);

        OleDbCommand cmd = new OleDbCommand("Select [Name],[city],[age] from [Sheet1$]", excelConnection);


            excelConnection.Open();




            cmd.ExecuteNonQuery();


            DataSet ds = new DataSet();
            SqlDataAdapter da = new SqlDataAdapter("Select [Name],[city],[age] from [Sheet1$]", strConnection);

            OleDbDataReader dReader;
            dReader = cmd.ExecuteReader();
            SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection);

            sqlBulk.DestinationTableName = "Test";
            sqlBulk.WriteToServer(dReader);
            excelConnection.Close();


    }
