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 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;
this.crystalReportViewer1.DockPadding.Bottom = 50;
this.crystalReportViewer1.DockPadding.Left = 5;
this.crystalReportViewer1.DockPadding.Right = 5;
this.crystalReportViewer1.DockPadding.Top = 5;
this.crystalReportViewer1.ReportSource = null;
设置button1的属性如下：
this.button1.Anchor = System.Windows.Forms.AnchorStyles.Bottom;
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( *.* )|*.*";
this.openFileDialog1.Title = "打开水晶报表";
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;
}
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：

private System.ComponentModel.Container components = null;

InitializeComponent( );
InitializeComponent 调用后添加任何构造函数代码
}
protected override void Dispose(bool disposing)

if ( components != null )

components.Dispose( );

}
base.Dispose(disposing);
