C# 检查是否已成功完成打印
我正在用c#开发windowform应用程序 在我的应用程序中,我编写了以下代码,从本地机器获取所有图像并打印出来C# 检查是否已成功完成打印,c#,.net,winforms,printing,C#,.net,Winforms,Printing,我正在用c#开发windowform应用程序 在我的应用程序中,我编写了以下代码,从本地机器获取所有图像并打印出来 files = Directory.GetFiles(@"C:\temp", "*.jpeg"); foreach (var i in files) { var objPrintDoc = new PrintDocument(); objPrintDoc.PrintPage += (obj, ev
files = Directory.GetFiles(@"C:\temp", "*.jpeg");
foreach (var i in files)
{
var objPrintDoc = new PrintDocument();
objPrintDoc.PrintPage += (obj, eve) =>
{
System.Drawing.Image img = System.Drawing.Image.FromFile(i);
Point loc = new Point(100, 100);
eve.Graphics.DrawImage(img, loc);
};
objPrintDoc.Print();
}
现在我想检查打印是否成功完成,然后我想删除我手动创建的临时文件夹来存储图像
我试过下面的代码,但对我不起作用
PrintServer myPrintServer;
PrintQueueCollection myPrintQueues = myPrintServer.GetPrintQueues();
String printQueueNames = "My Print Queues:\n\n";
foreach (PrintQueue pq in myPrintQueues)
{
printQueueNames += "\t" + pq.Name + "\n";
}
请让我们知道我的问题,并采取必要的措施
谢谢,Prashant这里是PrintSystemJobInfo.JobStatus的msdn说明 我尝试了以下代码并看到了打印状态
private void brnPrint_Click(object sender, EventArgs e)
{
var files = Directory.GetFiles(@"D:\Folder", "*.jpg");
foreach (var i in files)
{
var objPrintDoc = new PrintDocument();
objPrintDoc.PrintPage += (obj, eve) =>
{
Image img = Image.FromFile(i);
Point loc = new Point(100, 100);
eve.Graphics.DrawImage(img, loc);
};
objPrintDoc.Print();
PrintServer myPrintServer = new PrintServer(@"\\ComputerName");
PrintQueueCollection myPrintQueues = myPrintServer.GetPrintQueues();
try
{
foreach (PrintQueue pq in myPrintQueues)
{
pq.Refresh();
PrintJobInfoCollection pCollection = pq.GetPrintJobInfoCollection();
foreach (PrintSystemJobInfo job in pCollection)
{
listBox1.Items.Add(pq.Name);
SpotTroubleUsingJobAttributes(job);
}
}
}
catch (Exception)
{
//throw;
}
}
}
public void SpotTroubleUsingJobAttributes(PrintSystemJobInfo theJob)
{
if ((theJob.JobStatus & PrintJobStatus.Blocked) == PrintJobStatus.Blocked)

但它对我不起作用——它怎么不起作用?@AustinSalonen获取PrintQueueCollection myPrintQueues=myPrintServer.GetPrintQueues();我的意思是你期望什么,得到什么?@AustinSalonen我想检查一下打印是否成功?如果你的代码没有任何异常,那么你可以放心地认为打印机后台处理程序得到了作业,并负责将其发送到打印机。检查打印队列不可靠。很有可能你永远也看不到这份工作,因为它被迅速分派出去了。帮助也没有任何意义,如果打印文档时出现任何问题,用户已经从后台处理程序收到通知。
