Console.Clear可以用来仅清除行而不是整个控制台？ [英] Can Console.Clear be used to only clear a line instead of whole console?

问题描述

而关于学校的问题/应答程序的工作，它发生，我认为我可以使用 Console.Clear（）来消灭屏幕上的一切。我不知道如果我可以使用到Console.ReadLine（valueOne），那么只输出没有答案的问题。如果我只问了一个问题，在 Console.Clear 和

While working on a question/answer program for school, it occurred to me that I can use Console.Clear() to wipe out everything on the screen. I wonder if I can use Console.Readline(valueOne), then output only the answer without the question. If I only asked one question, the Console.Clear works.

我有没有值引用几个问题，如果可能的话抹掉。我要离开了问题，只显示几个答案。我想如果我储存的答案，我可以使用 Console.Clear（）然后就 Console.WriteLine（）与三个变量。我可以做这样的事情：

I have several questions with values not references, to erase if possible. I want to leave out the questions and only display several answers. I think if I store the answers, I could use Console.Clear() then just Console.WriteLine() with three variables. I could do something like this:

Console.WriteLine("Value 1 is: {0:c}" + "Value 2 is: {1:c}" + "Value 3 is: {2:c}, valueOne, valueTwo, valueThree).

问题是引用更容易，因为值被存储和检索。如果我只是使用方法按价值计算，输出的值，主要通过（）将不会有一个参考的数值要再次清除和输出。这就是为什么我想知道如果我可以问一个问题，然后删除该行并只输出答案（或答案）。

The problem is easier with references because the values are stored and retrieved. If I simply use methods to pass by value and output the value, main() will not have a reference to those values to clear and output again. That's why I wonder if I can just ask a question, then erase the line and output only the answer (or answers).

我只是想了解的可能性，而不是试图安装一个程序。我想知道输出从参考和值而无需额外的输出问题的值的能力。

I am just trying to understand the possibilities and not trying to setup a program. I like to know the abilities of outputting a value from reference and by value without extra output questions.

推荐答案

您可以使用 Console.SetCursorPosition 函数去一个特定的行号。
比你可以使用这个功能来清除行

Description

You can use the Console.SetCursorPosition function to go to a specific line number. Than you can use this function to clear the line

public static void ClearCurrentConsoleLine()
{
    int currentLineCursor = Console.CursorTop;
    Console.SetCursorPosition(0, Console.CursorTop);
    Console.Write(new string(' ', Console.WindowWidth)); 
    Console.SetCursorPosition(0, currentLineCursor);
}

示例

Console.WriteLine("Test");
Console.SetCursorPosition(0, Console.CursorTop - 1);
ClearCurrentConsoleLine();
