C#桌面办公应用-工资管理系统系列九
今天介绍介绍一下我自主开发的工资管理系统中的“汇总查询打印”模块，改小模块具有以下的功能：可以汇总统计员工的工资发放明细信息，可以查询指定的某个部门下的某些员工的工资发放明细信息，并打印成报表！开发的流程为：建立一个用于汇总的数据库表、制作报表、汇总、查询打印！我自己觉得这个功能是相当有趣的，而且在实际的企业中也具有一定的适用性，可以根据企业的需要自主定制相应的报表！若有博友想获取该系统的源码，或者想作为自己的毕业设计的系统实现，可以加我QQ:1974544863进行交流！
下面以“部门下的员工工资发放明细的汇总统计查询”为例，首先，建立汇总数据库表：tb_employeeSalarySummary
接着，制作企业定制的报表，采用的控件是微软的CrystalReport，即传说中的“水晶报表”。关于其制作过程，我觉得还是需要有技巧的，如果不知道这是个啥玩意，建议还是先去网上了解了解！！日后有时间了再来补充水晶报表的制作！下面是我自主制作的比较简陋的一个“员工工资发放明细”报表
接下来就是重点了，“汇总统计部门下某些或者某个员工的工资发放明细”或者“汇总统计单个员工的工资发放明细”。这个过程，实现起来还是挺辛苦的，由于涉及到“多个表与表之间的关联”，故而，在获取数据的时候，需要根据主外键进行关联，所以获取数据时候需要有一定的时间！
下面是“汇总部门下员工工资发放明细”的核心代码：

下面是点击“打印”之后打印报表的“报表界面”的制作：需要放置一个crystalReportView的控件
下面是进入“汇总统计查询初始化加载时候汇总统计部门下员工工资发放明细信息”事件代码：
private void frmPartEmployeeSalarySummary_Load(object sender, EventArgs e)
{
try
{
//汇总数据：“无”只是用来标识-这是“部门下员工工资的发放明细打印”
summaryEmpSalary.QueryPrintSalOfEmpFunc("全部", "无");
//加载信息
String strLoadSQL = "select salaryId as '工资编号',empId as '员工编号',empName as '员工姓名',partName as '所属部门',salaryYear as '工资年份',salaryMonth as '工资月份',salaryJinTie as '工资津贴',salaryFaJin as '罚金',basicSalaryType as '基本工资类型',basicSalary as '基本工资',rewardType as '奖励金类型',rewardSalary as '奖励金金额',salarySumAmount as '发放总金额',yearSumAmount as '改年总收入',salaryMemo as '备注信息' from tb_employeeSalarySummary ";
salaryPayDetailsService.bindSqlResultToDatagridView(dataGridViewSalaryPayDetailsInfo, strLoadSQL);
dataGridViewSalaryPayDetailsInfo.Columns[14].Width = 200;
}
catch (System.Exception ex)
{
Console.WriteLine("初始化家在信息出错: " + ex.Message);
}
}
下面是“打印”事件对应的源代码：
private void buttonSave_Click(object sender, EventArgs e)
{
//记录当前列表的行数以及工资编号数组
int salaryIdCount = 0;
int[] salaryIds;
try
{
int rows = dataGridViewSalaryPayDetailsInfo.Rows.Count;
if (rows == 0)
{
MessageBox.Show("当前没有可以打印的数据", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
return;
}
if (DialogResult.OK == MessageBox.Show("是否打印上述员工的工资发放明细信息？", "提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Exclamation))
{
salaryIdCount = rows;
salaryIds = new int[rows];
for (int i = 0; i < rows; i++)
{
//MessageBox.Show(dataGridViewSalaryPayDetailsInfo.Rows[i].Cells[0].Value.ToString().Trim());
salaryIds[i] = Convert.ToInt32(dataGridViewSalaryPayDetailsInfo.Rows[i].Cells[0].Value.ToString().Trim());
}
frmPrintEmployeeSalary printEmployeeSalary = new frmPrintEmployeeSalary(salaryIdCount, salaryIds);
printEmployeeSalary.ShowDialog();
}
}
catch (System.Exception ex)
{
Console.WriteLine("打印发生异常: " + ex.Message);
}
}using System;
using System.Collections.Generic;

{
public frmPrintEmployeeSalary(int rows,int[] salaryIds)
{

this.printRows = rows;
this.printSalaryIds = salaryIds;
}
DBOperate operate = new DBOperate();
//记录打印的两个数据
private int printRows;
private int[] printSalaryIds;
//测试数据
private void frmPrintEmployeeSalary_Load(object sender, EventArgs e)
{
}
//加载打印数据
private void crystalReportViewer1_Load(object sender, EventArgs e)
{
string strSQL = "";
try
{
strSQL = "select * from tb_employeeSalarySummary where salaryId = ";
for (int i = 0; i < printRows; i++)
{
strSQL += "'" + printSalaryIds[i] + "' or salaryId = ";
}
int index=strSQL.LastIndexOf("or");
//Console.WriteLine(index);
String newStr=strSQL.Substring(0, index);
Console.WriteLine("真正的打印语句： "+newStr);

String rootPath = Environment.CurrentDirectory;
String newPath=rootPath.Substring(0, rootPath.LastIndexOf("bin"));
String crystalReportPath = newPath + "crystalReport\\CrystalReportOne.rpt";
Console.WriteLine(crystalReportPath);
<span style="white-space:pre"> </span>//下面四条简洁的语句：将需要打印的数据塞进“打印”窗体中！这个很用的
ReportDocument doc = new ReportDocument();
doc.Load(crystalReportPath);
doc.SetDataSource(dsDrivOfPerMsg.Tables[0]);
crystalReportViewer1.ReportSource = doc;
}
catch (System.Exception ex)
{
MessageBox.Show("打印出错信息: \n" + ex.Message);
}
}
}
}
查询得到三条数据，下面点击“打印”，将打印“这三条数据”：
好了，今天介绍到这里吧！
需要说明的是，我自主的开发的这个工资管理系统的介绍已经接近尾声，当然了，其实还有其他很多功能：比如数据备份，比如基础数据的维护，比如如何查看通过软件查看帮助文档等等，这些我都会在系列10以一个文档进行介绍，有兴趣的博友可以下载浏览，这个管理系统可以作为个人毕业设计时的系统实现，如果觉得可以的话，可以加我QQ，我愿意低价出售给你！不过，还是那句话，主要是为了交流！
