控制台应用程序中的进度条

Progress bar in console application(控制台应用程序中的进度条)

问题描述

我正在编写一个简单的 c# 控制台应用程序，用于将文件上传到 sftp 服务器.但是，文件量很大.我想显示上传文件的百分比，或者仅显示要上传的文件总数中已上传​​的文件数.

I'm writing a simple c# console app that uploads files to sftp server. However, the amount of files are large. I would like to display either percentage of files uploaded or just the number of files upload already from the total number of files to be upload.

首先，我得到所有文件和文件总数.

First, I get all the files and the total number of files.

string[] filePath = Directory.GetFiles(path, "*");
totalCount = filePath.Length;

然后我遍历文件并在foreach循环中一一上传.

Then I loop through the file and upload them one by one in foreach loop.

foreach(string file in filePath)
{
    string FileName = Path.GetFileName(file);
    //copy the files
    oSftp.Put(LocalDirectory + "/" + FileName, _ftpDirectory + "/" + FileName);
    //Console.WriteLine("Uploading file..." + FileName);
    drawTextProgressBar(0, totalCount);
}

在 foreach 循环中，我有一个进度条，但我遇到了问题.无法正常显示.

In the foreach loop I have a progress bar which I have issues with. It doesn't display properly.

private static void drawTextProgressBar(int progress, int total)
{
    //draw empty progress bar
    Console.CursorLeft = 0;
    Console.Write("["); //start
    Console.CursorLeft = 32;
    Console.Write("]"); //end
    Console.CursorLeft = 1;
    float onechunk = 30.0f / total;

    //draw filled part
    int position = 1;
    for (int i = 0; i < onechunk * progress; i++)
    {
        Console.BackgroundColor = ConsoleColor.Gray;
        Console.CursorLeft = position++;
        Console.Write(" ");
    }

    //draw unfilled part
    for (int i = position; i <= 31 ; i++)
    {
        Console.BackgroundColor = ConsoleColor.Green;
        Console.CursorLeft = position++;
        Console.Write(" ");
    }

    //draw totals
    Console.CursorLeft = 35;
    Console.BackgroundColor = ConsoleColor.Black;
    Console.Write(progress.ToString() + " of " + total.ToString() + "    "); //blanks at the end remove any excess
}

输出只是 [ ] 0 out of 1943

The output is just [ ] 0 out of 1943

我在这里做错了什么?

我试图在加载和导出 XML 文件时显示进度条.然而，它正在经历一个循环.完成第一轮后进入第二轮，以此类推.

I'm trying to display the progress bar while I'm loading and exporting XML files. However, it's going through a loop. After it finishes the first round it goes to the second and so on.

string[] xmlFilePath = Directory.GetFiles(xmlFullpath, "*.xml");
Console.WriteLine("Loading XML files...");
foreach (string file in xmlFilePath)
{
     for (int i = 0; i < xmlFilePath.Length; i++)
     {
          //ExportXml(file, styleSheet);
          drawTextProgressBar(i, xmlCount);
          count++;
     }
 }

它永远不会离开 for 循环...有什么建议吗?

It never leaves the for loop...Any suggestions?

推荐答案

这行是你的问题:

drawTextProgressBar(0, totalCount);

您是说每次迭代的进度都为零，这应该增加.也许改用 for 循环.

You're saying the progress is zero in every iteration, this should be incremented. Maybe use a for loop instead.

for (int i = 0; i < filePath.length; i++)
{
    string FileName = Path.GetFileName(filePath[i]);
    //copy the files
    oSftp.Put(LocalDirectory + "/" + FileName, _ftpDirectory + "/" + FileName);
    //Console.WriteLine("Uploading file..." + FileName);
    drawTextProgressBar(i, totalCount);
}
