发送取消参数C＃

好的，这是我的整个代码。现在... Detail_BeforePrint()将首先被调用，并且xrPictureBox8_BeforePrint秒。现在我想拨打Detail_BeforePrinte.Cancel = true;里面的else在xrPictureBox8_BeforePrint事件。发送取消参数C＃

private void Detail_BeforePrint(object sender, System.Drawing.Printing.PrintEventArgs e) 
     { 
    //here should e.Cancel = true be if it came from xrPictureBox_BeforePrint() 
     } 

    private void xrPictureBox8_BeforePrint(object sender, System.Drawing.Printing.PrintEventArgs e) 
    { 
     try 
     { 
      if (xrPictureBox8.ImageUrl.Length > 0) { } 
      else 
      { 
      Detail_BeforePrint(null,[call Cancel parameter]); 
      } 

     } 
     catch (Exception) 
     { 

     } 
    }

这个问题太模糊了 - 我现在读了3遍，我还不确定你需要什么帮助。你想要完成什么，以及你的问题到底是什么。还提供了一个代码示例。 – user1666620

也许会有这样的帮助吗？

private void Detail_BeforePrint(object sender, System.Drawing.Printing.PrintEventArgs e) 
{ 
    DoDetail_BeforePrint(e, false); 
} 

private void DoDetail_BeforePrint(System.Drawing.Printing.PrintEventArgs e, bool cancel) 
{ 
    if (cancel) e.Cancel = true; 
    //other things 
} 

private void xrPictureBox8_BeforePrint(object sender, System.Drawing.Printing.PrintEventArgs e) 
{ 
    try 
    { 
     if (xrPictureBox8.ImageUrl.Length > 0) { } 
     else 
     { 
      DoDetail_BeforePrint(e, true); 
      //or just call e.Cancel = true here? 
     } 
    } 
    catch (Exception) 
    { 
    } 
}
