如何在C#-devexpress中打印gridview双面打印

我想用双面打印gridview，我尝试了下面显示的代码。但是这一行显示了错误

xtrareport1r=newxtrareport1（）。打印gridView时如何使其工作？
我明白了

CS0246:找不到类型或命名空间名称“XtraReport1”。
是否缺少using指令或程序集引用


浏览文档：








要打印网格控件，应使用
或方法
然后处理事件以自定义打印设置
请参阅此示例，该示例让您了解如何访问打印事件以进行进一步自定义：

public Form1()
{
    InitializeComponent();
    sqlDataSource1.Fill();

}

private void button1_Click(object sender, EventArgs e)
{
    gridControl1.Print();
}

private void gridView1_PrintInitialize(object sender, DevExpress.XtraGrid.Views.Base.PrintInitializeEventArgs e)
{
    PrintingSystemBase pb = e.PrintingSystem as PrintingSystemBase;
    pb.StartPrint -= pb_StartPrint;
    pb.StartPrint +=pb_StartPrint;


}

void pb_StartPrint(object sender, PrintDocumentEventArgs e)
{
    e.PrintDocument.PrinterSettings.Duplex = System.Drawing.Printing.Duplex.Horizontal;
    //e.PrintDocument.PrinterSettings.PrintToFile = true;
    e.PrintDocument.PrinterSettings.PrinterName = "Foxit Reader PDF Printer";

}

不如你发布实际的错误，或者用谷歌搜索错误。也许
XtraReport r=newxtrareport（）
？@LarsTech yes我得到
CS0246:找不到类型或命名空间名称
XtraReport1'。是否缺少using指令或程序集引用？`error@user6144226我添加了需要包含程序集的错误/将正确的using添加到定义xtrareport1的命名空间谢谢。文档中没有任何关于双面打印gridcontrol的内容。@user8066749:更新我的答案，现在您可以在开始打印事件时访问打印机设置。。希望这对你有帮助。。
public Form1()
{
    InitializeComponent();
    sqlDataSource1.Fill();

}

private void button1_Click(object sender, EventArgs e)
{
    gridControl1.Print();
}

private void gridView1_PrintInitialize(object sender, DevExpress.XtraGrid.Views.Base.PrintInitializeEventArgs e)
{
    PrintingSystemBase pb = e.PrintingSystem as PrintingSystemBase;
    pb.StartPrint -= pb_StartPrint;
    pb.StartPrint +=pb_StartPrint;


}

void pb_StartPrint(object sender, PrintDocumentEventArgs e)
{
    e.PrintDocument.PrinterSettings.Duplex = System.Drawing.Printing.Duplex.Horizontal;
    //e.PrintDocument.PrinterSettings.PrintToFile = true;
    e.PrintDocument.PrinterSettings.PrinterName = "Foxit Reader PDF Printer";
