本文介绍了C#中的打印机管理器的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 我有3台打印机,而且,我想要打印很多文件,所以,我想知道,我怎么能制作一个简单的系统来管理这台打印机,我知道这个基础,但是,我想知道知道,我如何打印机打印并继续验证,以便在另一台打印机上打印更多文件...所以,基本上我的意思是: private void printer() { int number = 0 ; GetPrintStatus gps = new GetPrintStatus(); for ( int i = 0 ; i < 5 ; i ++) { 如果(数字> 4 ) number = 0 ; gps.SetPrinter = string .Format( HP - {0},数字); switch (gps.ToString()) { case HP - 0: if (gps.Status!= status.Enable) gps.print( 1.pdf ); break ; case HP - 1: if (gps.Status!= status.Enable) gps.print( 1.pdf); break ; case HP - 2: if (gps.Status!= status.Enable) gps.print( 1.pdf); break ; case HP - 3: if (gps.Status!= status.Enable) gps.print( 1.pdf); break ; case HP - 4: if (gps.Status!= status.Enable) gps.print( 1.pdf); break ; } } 好的,但是,代码转到:gps.print ,代码停在那里,然后,当打印机返回正常时继续....但是,我怎么做,代码继续?解决方案 请参阅我的评论问题。 我真的认为你有更严重的问题。在已经是字符串的对象上调用 ToString 。用完全相同的数据重复完全相同的代码5次。 (从未听说过抽象?方法?方法参数?不要重复自己的原则?)你的奇怪认为你总是有5台打印机,而不是2台,而不是6台,以及你准备好为5台打印机专门编写代码...... 这没有任何意义,但即使有某种意义......如果我有一些问题,我会忘记打印。为什么要浪费时间? -SA I have 3 printers, and, I whant to print a lot of files, so, I whant to know, how I can make a little and simple system to manage this printers, the base I know, but, I whant to know, How I can make the printer print and continue with verification to put more files to print in another printer... so, basicly what I mean is:private void printer(){ int number = 0; GetPrintStatus gps = new GetPrintStatus(); for (int i = 0; i < 5; i++) { if (number > 4) number = 0; gps.SetPrinter = string.Format("HP - {0}", number); switch (gps.ToString()) { case "HP - 0": if (gps.Status != status.Enable) gps.print("1.pdf"); break; case "HP - 1": if (gps.Status != status.Enable) gps.print("1.pdf"); break; case "HP - 2": if (gps.Status != status.Enable) gps.print("1.pdf"); break; case "HP - 3": if (gps.Status != status.Enable) gps.print("1.pdf"); break; case "HP - 4": if (gps.Status != status.Enable) gps.print("1.pdf"); break; } }OK, But, when the code go to: gps.print, to code stop there, and, continue when the printer return ok.... but, how I can do, to code continue ? 解决方案 Please see my comment to the question.I really think you have more serious problems. Calling ToString on the object which is already a string. Repeating totally identical code with almost identical data 5 times. (Never heard of abstractions? Method? Method parameters? Don''t Repeat Yourself principle?) Your strange believe that you will always have 5 printers, not 2, not 6, as well as your readiness to write code specifically for 5 printers…It makes no sense, but even if there was some sense… If I had some of your problems, I would forget about printing at all. Why wasting time?—SA 这篇关于C#中的打印机管理器的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 10-30 05:23
