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*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：

事实上，将报表绑定到CrystalReportViewer控件有很多方法。
