如何在 C# 中使用 PrintDialog 打印文檔 (How to print a document using PrintDialog in C#)

問題描述

如何在 C# 中使用 PrintDialog 打印文檔 (How to print a document using PrintDialog in C#)

這是我的示例代碼。但它打印一個空頁面

            printDocument1.DocumentName = "C:\a.pbf";// PrintDocument printDocument1
            printDialog1.Document = printDocument1;
            printDialog1.AllowPrintToFile = true;
            printDialog1.AllowSelection = true;
            printDialog1.AllowSomePages = true;
            printDialog1.PrintToFile = true;
            if (printDialog1.ShowDialog() == DialogResult.OK)
                printDocument1.Print();

這有什麼問題嗎？請幫幫我

參考解法

方法 1:

You need to handle the PrintPage event to actually provide the contents; MSDN has a full example. The DocumentName is purely something to show to the user ‑ it is not the path of an existing file to magically print.

For printing an existing PDF, maybe look at this question

方法 2:

do this :

public static void PrintToASpecificPrinter()
        {     
                using (PrintDialog printDialog=new PrintDialog ())
                {
                printDialog.AllowSomePages = true;
                printDialog.AllowSelection = true;
                if (printDialog.ShowDialog() == DialogResult.OK)
                {
                    var StartInfo = new ProcessStartInfo();
                    StartInfo.CreateNoWindow = true;
                    StartInfo.UseShellExecute = true;
                    StartInfo.Verb = "printTo";
                    StartInfo.Arguments = "\"" + printDialog.PrinterSettings.PrinterName + "\"";
                    StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
                    StartInfo.FileName = fileName;

                    Process.Start(StartInfo);
                }

                }


        }
