在C#Windows应用程序中使用通用/文本打印机更改字体 [英] Changing Font with Generic/Text Printer in C# Windows Application

问题描述

我想在C#Windows应用程序中打印文本.
为此，我安装了通用/文本打印机.
在C Sharp Code中，我写为:

I want text printing in C# Windows Application.
For this I installed a Generic/Text Printer.
in C Sharp Code I have written as :

string dwon,dwof;
StreamReader streamToPrint;
Font printFont;
dwon = string.Format("{0}{1}", Convert.ToChar(27), Convert.ToChar(69));
dwof = string.Format("{0}{1}", Convert.ToChar(27), Convert.ToChar(70));
            StreamWriter sw = new StreamWriter(@"G:\TEST.TXT");
            sw.WriteLine(dwon+"Manoj Dua"+dwof);
            sw.WriteLine("Gandhi Colony");
            sw.WriteLine("Muzaffarnagar");
            sw.Close();
            try
            {
                streamToPrint = new StreamReader(@"G:\Test.txt");
                try
                {
                    printFont = new Font("Courier", 10);
                    PrintDocument pd = new PrintDocument();
                    pd.PrintPage += new PrintPageEventHandler
                       (this.pd_PrintPage);
                    pd.Print();
                }
                finally
                {
                    streamToPrint.Close();
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }

但是Manoj Kumar并未以粗体显示.

在Manoj Kumar之前打印E，在Manoj Kumar之后打印F

错误在哪里，请告诉我.

请帮助

But Manoj Kumar is not printed in bold.

It prints E before Manoj Kumar and F after Manoj Kumar

Where is Mistake, Please tell me.

Please Help

推荐答案

dwon = string.Format("{0}{1}", Convert.ToChar(27), Convert.ToChar(69));
dwof = string.Format("{0}{1}", Convert.ToChar(27), Convert.ToChar(70));

因为Char 69是E而Char 70是F.

string.format重载，您说的是ESC，然后将E放入dwon，将ESC和F放入dwof.
然后将其打印出来，您未指定要粗体显示任何文本.

Because Char 69 is an E and Char 70 is an F.

The string.format is overloaded and you are saying Put in an ESC then an E to dwon and an ESC and an F to dwof.
That is then being printed, you are not specifying that you want to Bold any text.
