Excel文件未使用值插入表中

Question

我必须使用值将excel文件插入表中。应通过下拉列值获取列的ID。其余的列值已通过Excel工作表插入。问题是，我编写了代码，但是没有将值插入到表中。 请参阅代码供您参考： -

protected void btnImport_Click(object sender, EventArgs e)
{
    string name;
    string storename;
    string address;
    string city;
    int Id;
    DataTable dt = new DataTable();
    foreach (DataRow row in dt.Rows)
    {
        name = row["Merchant_Name"].ToString();
        storename = row["Store_Name"].ToString();
        address = row["Store_Address"].ToString();
        city = row["City"].ToString();
        Id = int.Parse(row["CategoryId"].ToString());
        this.InsertRows(Id, name, storename, address, city);
    }
    if (FileUpload1.HasFile)
    {
        string sPath = Server.MapPath(FileUpload1.FileName);
        FileUpload1.SaveAs(sPath);
        Response.Write("<script>alert('File uploaded successfully');</script>");
    }
}

private void InsertRows(int Id, string name, string storename, string address, string city)
{

    string sSourceConstr1 = string.Format(@"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\AgentList.xls; Extended Properties=""Excel 8.0;HDR=YES;""");
    string sSourceConstr = string.Format(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=""Excel 12.0 Xml;HDR=YES;""");

    OleDbConnection sSourceConnection = new OleDbConnection(sSourceConstr);

    string constrng = ConfigurationManager.ConnectionStrings["DefaultSQLConnectionString"].ConnectionString;
    using (SqlConnection conn = new SqlConnection(constrng))
    {
        using (SqlCommand cmd = new SqlCommand(@"Insert Into MerchantDataTable values (@CategoryId, @MerchantName, @StoreName, @StoreAddress, @City)", conn))
        {
            cmd.Parameters.AddWithValue("@CategoryId", Id);
            cmd.Parameters.AddWithValue("@MerchantName", name);
            cmd.Parameters.AddWithValue("@StoreName", storename);
            cmd.Parameters.AddWithValue("@StoreAddress", address);
            cmd.Parameters.AddWithValue("@City", city);
            conn.Open();
            cmd.ExecuteNonQuery();
            conn.Close();
        }
    }
}
