 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:
