推荐答案

ReportDocument objCrystalReport = new ReportDocument();
objCrystalReport.Load(AppDomain.CurrentDomain.BaseDirectory + @".. \ StudentRecord.rpt");
objDataSet.Clear();
objDataSet.ReadXml(AppDomain.CurrentDomain.BaseDirectory + @".. \ StudentData.xml");
StudentRecordData objRecords =新的StudentRecordData();
Program.LoadForm = true;
如果(objDataSet！= null&& objDataSet.Tables.Count> 0)
{
如果(objDataSet.Tables [0] .Rows.Count> 0)
{
int计数器= 0;
foreach(objDataSet.Tables [0] .Rows中的DataRow objRow)
{
if(计数器<((int)(objDataSet.Tables [0] .Rows.Count)/2))
{
objRecords.Student.ImportRow(objRow);
}
其他
{
objRecords.Student_Addition.ImportRow(objRow);
}
counter ++;
}
}
其他
{
MessageBox.Show(无法创建报告");
Program.LoadForm = false;
this.Close();
}

objCrystalReport.SetDataSource(objRecords);
crystalReportViewer1.ReportSource = objCrystalReport;
crystalReportViewer1.Show();

ReportDocument objCrystalReport = new ReportDocument();
objCrystalReport.Load(AppDomain.CurrentDomain.BaseDirectory + @"..\StudentRecord.rpt");
objDataSet.Clear();
objDataSet.ReadXml(AppDomain.CurrentDomain.BaseDirectory + @"..\StudentData.xml");
StudentRecordData objRecords = new StudentRecordData();
Program.LoadForm = true;
if (objDataSet != null && objDataSet.Tables.Count > 0)
{
if (objDataSet.Tables[0].Rows.Count > 0)
{
int counter = 0;
foreach (DataRow objRow in objDataSet.Tables[0].Rows)
{
if (counter < ((int)(objDataSet.Tables[0].Rows.Count) / 2))
{
objRecords.Student.ImportRow(objRow);
}
else
{
objRecords.Student_Addition.ImportRow(objRow);
}
counter++;
}
}
else
{
MessageBox.Show("Not able to Create Report");
Program.LoadForm = false;
this.Close();
}

objCrystalReport.SetDataSource(objRecords);
crystalReportViewer1.ReportSource = objCrystalReport;
crystalReportViewer1.Show();
