showing percentage in .net console application
提问by Ronnie Overby
I have a console app that performs a lengthy process.
我有一个控制台应用程序，它执行一个漫长的过程。
I am printing out the percent complete on a new line, for every 1% complete.
我在新行上打印完成百分比，每完成 1% 完成。
How can I make the program print out the percent complete in the same location in the console window?
如何让程序在控制台窗口的同一位置打印完成百分比？
采纳答案by Jon Skeet
Print \rto get back to the start of the line (but don't print a newline!)
打印\r回到行首（但不要打印换行符！）
For example:
例如：
using System;
using System.Threading;
class Test
{
static void Main()
{
for (int i=0; i <= 100; i++)
{
Console.Write("\r{0}%", i);
Thread.Sleep(50);
}
}
}

You may use:
您可以使用：
Console.SetCursorPosition();
To set the position appropriately.
适当地设置位置。
Like so:
像这样：
Console.Write("Hello : ");
for(int k = 0; k <= 100; k++){
Console.SetCursorPosition(8, 0);
Console.Write("{0}%", k);
System.Threading.Thread.Sleep(50);
}
Console.Read();
