如何更改mainreport tab上的标题如下：private void SetReportName(CrystalReportViewer CrystalReportViewer1, string newName)
{
 foreach(Control control in CrystalReportViewer1.Controls)
 if (control is CrystalDecisions.Windows.Forms.PageView)
    foreach(Control controlInPage in control.Controls)
    if (controlInPage is TabControl)
   foreach(TabPage tabPage in (controlInPage as TabControl).TabPages)
   if (tabPage.Text == "MainReport")
   {
     tabPage.Text = newName;
     return;
   }
}
