   大名鼎鼎的 Crystal Reports(水晶报表)已内嵌为微软 Visual Studio .NET的标准报表工具,同时升级到 Crystal Reports for Visual Studio .NET。它的优点是:1、在 .NET 平台能够轻松创建交互式的、高质量显现的报表内容,这也是 Crystal Reports 长期以来所具有的主要优势;2、使用 Crystal Reports for Visual Studio .NET,可以在 Web 平台和 Windows 平台上承载报表,并将 Crystal 报表作为报表 Web 服务在 Web 服务器上发布;3、利用Crystal Report 创建的Web应用程序,使用户可以深化图表并根据需要筛选信息。在 .NET 中,图表实际上就是一个与应用程序中其他控件进行交互的 Crystal 报表。在这里我向大家介绍如何在 Windows 窗体应用程序中浏览水晶报表。    设计步骤:    1、软件环境:要求系统已安装Visual Studio .Net 集成开发系统,仅装有 .Net Framework SDk 不能实现本例效果,成为 .Net Framework SDK 没有水晶报表控件。    2、新建一个 Visual C# 项目 Windows 应用程序,设置Form1的Text="水晶报表浏览器",StartPosition=CenterScreen //程序开始出现在屏幕中央,其它属性均保持默认;    3、从工具箱拖入一个CrystalReportViewer,一个Button,一个openFileDialog,到窗体。    整个设计器的窗体布局只需将button1置于窗体底边中部,不再需要其它多余布局。    设置crystalReportViewer1的属性如下:  this.crystalReportViewer1.Dock = System.Windows.Forms.DockStyle.Fill;  //停靠方式为充满整个窗体 //展开+DockPadding this.crystalReportViewer1.DockPadding.Bottom = 50;  //底部空出放置Button的区域 this.crystalReportViewer1.DockPadding.Left = 5;  this.crystalReportViewer1.DockPadding.Right = 5; this.crystalReportViewer1.DockPadding.Top = 5; this.crystalReportViewer1.ReportSource = null;  //先不载入报表资源    设置button1的属性如下:  this.button1.Anchor = System.Windows.Forms.AnchorStyles.Bottom; //与窗体的下边保持固定 this.button1.Text = "打开报表"; openFileDialog1是打开文件的控件,设置其属性如下:  this.openFileDialog1.Filter  = "Crystal Report (*.rpt)|*.rpt|所有文件(*.*)|*.*";  //提供打开文件对话框的文件类型, 默认类型就是此字符串的最前一种定义的类型 this.openFileDialog1.Title = "打开水晶报表";  //打开文件对话框的标题     布局效果图如下: 
   
   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
