1、利用shell命令,调用进程打印
string pdfPath = “testPrint.xps";
Process proc = new Process
{
StartInfo =
{
CreateNoWindow = false,
WindowStyle = ProcessWindowStyle.Hidden,
UseShellExecute = true,
FileName = pdfPath,
Verb = "print" //Verb(谓词),它可以通过FileName属性的扩展名(不管FileName存不存在)并查询注册表返回相应文件类型的Shell菜单
命 令,常见有“print”打印,,“open”打开,“edit”编辑,“runas”管理员身份运行
}
};
proc.Start();
//proc.WaitForExit();
proc.Close();
注:此方法适合打印已存在的文件。
2、利用PrintDialog打印xaml页面
FixedPage printPage = (FixedPage)Application.LoadComponent(new Uri(@"../Print.xaml", UriKind.Relative));
PageContent pageContent = new PageContent();
FixedDocument fixedDoc = new FixedDocument();
fixedDoc.DocumentPaginator.PageSize = new Size(96 * 8.5, 96 * 11);
((IAddChild)pageContent).AddChild(printPage);
fixedDoc.Pages.Add(pageContent);
dialog.PrintDocument(fixedDoc.DocumentPaginator, "打印报告");
如果需要预览就要用到DocumentViewer控件,设置Document即可。
3、利用PrintDialog打印界面控件
private void Button_Click(object sender, RoutedEventArgs e)
{
PrintDialog dialog = new PrintDialog();
if (dialog.ShowDialog() == true)
{
dialog.PrintVisual(grid, "PrintTest");
