使用ReportView控件可以显示远端Report service的报表，也可以处理生成本地报表，用法也比较简单，下面列举一下简单的步骤。
首先使用Report Wizard添加一个rdlc报表文件到工程项目，使用这个wizard会自动创建报表使用的DataSet等，其实这些后面都可以用自己的DataSource来替换掉。设计好一个Table的报表，在报表中添加FromDate和ToDate两个参数，然后添加两个TextBox在报表上显示这两个参数的值。
然后添加一个ReportView控件到Form，在一个按钮事件中来初始化和刷新报表：
1 private void button1_Click(object sender, EventArgs e)
2 {
3 reportViewer1.LocalReport.ReportEmbeddedResource = " ReportsApplication1.Report1.rdlc ";
4
5 ReportDataSource reportDataSource= new ReportDataSource();
6 reportDataSource.Name = " MESDBDataSet_ProdFinish ";
7 reportDataSource.Value = getProdFinishTable();
8 reportViewer1.LocalReport.DataSources.Clear();
9 reportViewer1.LocalReport.DataSources.Add(reportDataSource);
10
11 ReportParameter fromParam= new ReportParameter( " FromDate ",dateTimePicker1.Value.ToShortDateString());
12 ReportParameter toParam = new ReportParameter( " ToDate ", dateTimePicker1.Value.ToShortDateString());
13
14 reportViewer1.LocalReport.SetParameters( new ReportParameter[]{fromParam,toParam});
15 reportViewer1.RefreshReport();
16 }
17
18 private DataTable getProdFinishTable()
19 {
20
21 SqlConnection connection= new SqlConnection(Properties.Settings.Default.MESDBConnectionString);
22 connection.Open();
23 string sql = " select * from prodfinish where proddate>=@fromdate and proddate<dateadd(day,1,@todate) ";
24 SqlDataAdapter adapter= new SqlDataAdapter(sql,connection);
25 adapter.SelectCommand.Parameters.AddWithValue( " fromdate ",dateTimePicker1.Value.Date);
26 adapter.SelectCommand.Parameters.AddWithValue( " todate ", dateTimePicker2.Value.Date);
27 DataTable dataTable = new DataTable();
28 adapter.Fill(dataTable);
29 connection.Close();
30 return dataTable;
31 }
3 reportViewer1.LocalReport.ReportEmbeddedResource = " ReportsApplication1.Report1.rdlc ";
4
5 ReportDataSource reportDataSource= new ReportDataSource();
6 reportDataSource.Name = " MESDBDataSet_ProdFinish ";
7 reportDataSource.Value = getProdFinishTable();
8 reportViewer1.LocalReport.DataSources.Clear();
9 reportViewer1.LocalReport.DataSources.Add(reportDataSource);
10
11 ReportParameter fromParam= new ReportParameter( " FromDate ",dateTimePicker1.Value.ToShortDateString());
12 ReportParameter toParam = new ReportParameter( " ToDate ", dateTimePicker1.Value.ToShortDateString());
13
14 reportViewer1.LocalReport.SetParameters( new ReportParameter[]{fromParam,toParam});
15 reportViewer1.RefreshReport();
16 }
17
18 private DataTable getProdFinishTable()
19 {
20
21 SqlConnection connection= new SqlConnection(Properties.Settings.Default.MESDBConnectionString);
22 connection.Open();
23 string sql = " select * from prodfinish where proddate>=@fromdate and proddate<dateadd(day,1,@todate) ";
24 SqlDataAdapter adapter= new SqlDataAdapter(sql,connection);
25 adapter.SelectCommand.Parameters.AddWithValue( " fromdate ",dateTimePicker1.Value.Date);
26 adapter.SelectCommand.Parameters.AddWithValue( " todate ", dateTimePicker2.Value.Date);
27 DataTable dataTable = new DataTable();
28 adapter.Fill(dataTable);
29 connection.Close();
30 return dataTable;
31 }
