这可能是一个简单的问题,我只是没有弄清楚如何正确地说出来。无论如何,请允许我描述我的问题。
所以我写了一个程序,帮助用户管理他们的程序安装。出于显而易见的原因,我提供了对此应用程序的GUI和命令行访问(GUI在WPF中)。
无论如何,我的问题是输出一堆文本到命令行。这是我的代码:
void WriteHelp()
{
// Attach to console to write out to it
if (AttachConsole(-1))
{
Console.WriteLine("InstallAssist helps maintain your Shine Calendar installation.");
Console.WriteLine("Version " + VERSION_STRING + " (" + VERSION_ID + ")");
Console.WriteLine("Written by Jayke R. Huempfner. Copyright 2018.");
Console.WriteLine();
Console.WriteLine("Can be accessed through GUI or by using the arguments below:");
Console.WriteLine();
Console.WriteLine("Argument Action");
Console.WriteLine("-------- ------");
Console.WriteLine("-about (-a) Displays version/system info");
Console.WriteLine("-hardreset (-hr) Perform a hard reset");
Console.WriteLine("-help (-?) Displays this help page.");
Console.WriteLine("-info (-i) Displays version/system info");
Console.WriteLine("-quiet (-q) Quiet mode, don't display GUI");
Console.WriteLine("-reset (-e) Display reset options GUI");
Console.WriteLine("-skipconfirm (-sc) Skip confirmation GUI screen");
Console.WriteLine("-softreset (-s) Perform a soft reset");
Console.WriteLine("-uninstall (-u) Uninstall, keeping user data");
Console.WriteLine("-uninstallall (-ua) Uninstall, deleting user data");
Console.WriteLine();
Console.WriteLine("More information available online at:");
Console.WriteLine("https://shinecalendar.com/help/advanced");
}
}
看起来很简单,不是吗?我认为结果会非常明显。但是,当我进入PowerShell并访问它时,这就是我得到的:
PS C:\Users\jacob\Documents\Visual Studio 2017\Projects\ShineCalendar\ShineWin\bin\Release> .\InstallAssist.exe -help
PS C:\Users\jacob\Documents\Visual Studio 2017\Projects\ShineCalendar\ShineWin\bin\Release> InstallAssist helps maintain your Shine Calendar installation.

格式化出来都没问题,但问题是顶行被写入下一个命令输入。当我开始输入更多命令和诸如此类的东西时,它最终会覆盖行。 (即:
PS C:\Users\jacob\Documents\Visual Studio 2017\Projects\ShineCalendar\ShineWin\bin\Release> .\InstallAssist.exe -help
PS C:\Users\jacob\Documents\Visual Studio 2017\Projects\ShineCalendar\ShineWin\bin\Release> dir
lation.

Mode LastWriteTime Length Name
---- ------------- ------ ----
-a---- 9/9/2016 2:59 PM 77312 CsvHelper.dll
... (rest omitted)
)
我该怎么做才能写出输出然后显示整个"PS C:\Users\...\bin\Release>"
的内容?

您的问题是您的应用程序立即(作为WPF启动代码的一部分)释放控制台。然后cmd.exe准备通过打印提示接受更多输入。
然后,您重新连接到控制台并开始输出帮助文本。但cmd.exe不知道这一点,因此控制台出现乱码。
我建议通过制作两个程序来修复它。按原样保留WPF应用程序,但在前面添加一个小型控制台应用程序。控制台应用程序打印您想要的文本(如果需要),然后启动您的WPF应用程序。
