How Can I Update the Current Line in a C# Windows Console App Without Creating a New Line?

Update current row in C# Windows console application

Background: When developing a Windows console application using C#, it may be necessary to update the current line without wrapping it. For example, when displaying a progress percentage, you may want to update the percentage value on the same row, rather than writing on a new row with each update.

Solution:

Yes, it is possible to update the current line in a C# Windows console application without wrapping. This can be achieved by using the "r" and "Write()" methods in combination.

Code:

for (int i = 0; i < 101; i++)
{
    Console.Write("\r{0}%      ", i); // 使用\r回到行首，并用Write()方法防止换行
    Thread.Sleep(100); // 模拟进度更新
}

Instructions:

• The "r" character, when written to the console, moves the cursor to the beginning of the current line, effectively overwriting it.
• Use the "Write()" method instead of the "WriteLine()" method to prevent extra line breaks from being added.
• To ensure that the previous content is cleared, some spaces are added after the percentage value.
