4、双击button1,添加button1_Click点击事件:

private void button1_Click(object sender, System.EventArgs e)
{
 try
 {
  if(openFileDialog1.ShowDialog()==DialogResult.OK)
   this.crystalReportViewer1.ReportSource = @openFileDialog1.FileName;
   //加载水晶报表,将报表文件绑定到CrystalReportView 控件;
 }
 catch(Exception error)
 {
  MessageBox.Show(error.ToString(),"错误");
 }
}

  5、OK!按Ctrl+F5运行吧。

  可以浏览你系统内现有的报表实例:

...\Program Files\Microsoft Visual Studio .NET\Crystal Reports\Samples\Reports\Feature Examples\Chart.rpt
