Question

我想为月份生成员工报告。但我不能这样做。我只是试着这样做。但它只返回最后一个员工记录。

使用列表框并选择多个员工生成报告。但我不能这样做。

我的部分鳕鱼在这里..

DataSet4TableAdapters.sp_getalltimesheetTableAdapter TA1 = new DataSet4TableAdapters.sp_getalltimesheetTableAdapter();
DataSet4.sp_getalltimesheetDataTable DS1 = TA1.GetData();
foreach (DataRow dr in DS1.Rows)
{
    string name = Convert.ToString(dr["Employee_ID"]) + "-" + Convert.ToString(dr["Employee_Name"]);
    for (int i = 0; i < lbxempname.Items.Count; i++ )

        if (lbxempname.Items[i].Selected)

            string id = lbxempname.Items[i].Text;
            if (name == id)

                        string PunchDate = oItem.Cells[3].Text;
                        string Day = oItem.Cells[4].Text;
                        string intime = oItem.Cells[5].Text;
                        string outtime = oItem.Cells[6].Text;

                        groupdetails(empid, empname, PunchDate, dept, intime, outtime);
                        if (intime == "" || outtime == "")
                        {
                            remark = "A";
                        }
                        else
                        {
                            remark = "P";
                        }
                        dr1["EmployeeId"] = Convert.ToString(empid);
                        dr1["EmployeeName"] = Convert.ToString(empname);
                        dr1["Department"] = Convert.ToString(dept);
                        dr1["Date"] = Convert.ToString(PunchDate);
                        dr1["Day"] = Convert.ToString(Day);
                        dr1["Intime"] = Convert.ToString(intime);
                        dr1["Outtime"] = Convert.ToString(outtime);
                        dr1["Late_After"] = Convert.ToString(Session["late"].ToString());
                        dr1["Early_Before"] = Convert.ToString(Session["early"].ToString());
                        dr1["Remarks"] = Convert.ToString(remark);
                        dt.Rows.Add(dr1);
                        ViewState["new"] = dt;

                    }
                }
            }

        }

    }
}
grdvw.DataSource = ViewState["new"];
grdvw.DataBind();
System.IO.StringWriter stringwriter = new StringWriter();
HtmlTextWriter htmlwriter = new HtmlTextWriter(stringwriter);
grdvw.RenderControl(htmlwriter);
Response.Write(stringwriter.ToString());
Response.End();

它返回上一个选定员工的输出。但我想从列表框中选择所有员工记录请帮我... 我的输出是这样的......

   EmployeeId   EmployeeName    Department  Date            Day     Intime      Outtime     Late_After  Early_Before    Remarks

以上报告是列表框最后选择的员工。我想为所有员工提供这种报告，并且有一点小小的突破......

我做过同样的事情，请查看此链接描述了整个代码和场景，我认为它会对你有所帮助

Answer 2

我建议看看NPOI，一个Apache POI的.NET移植;此库允许您从API生成MS Office文件，而不需要任何其他依赖项，例如前端对象，MS Office安装等。）
