带有VB.NET控制台应用程序的进度条

我已经编写了一个解析实用程序作为控制台应用程序，并且它工作得非常顺利。该实用工具读取带分隔符的文件，并根据用户值作为命令行参数将记录拆分为两个文件之一（好记录或坏记录）

正在查看进度条或状态指示器，以显示解析时已执行的工作或剩余的工作。我可以很容易地在循环中在屏幕上写一个a，但我想给出一个%

1首先，你必须知道你需要多少行。 在循环中计算“intLineCount/100*intCurrentLine”

并使用SetCursor方法在循环中的同一位置打印结果

VB.NET：

Dim totalLines as Integer = 0
Dim currentLine as integer = 0
For Each line as string in Lines
     ' Your operation

     currentLine += 1I
     Dim Progress as integer = (currentLine / totalLines) * 100

    ' print out the result with the suggested method...
    ' !Caution: if there are many updates consider to update the output only if the value has changed or just every n loop by using the MOD operator or any other useful approach

最简单的方法是经常更新progressBar变量， 例如：如果您的代码由大约100行组成，或者可能是100个功能

---

在每个函数或某些代码行使用百分比更新progressbar变量后：）

下面是一个如何计算完成百分比并将其输出到进度计数器中的示例：

Option Strict On
Option Explicit On

Imports System.IO

Module Module1
    Sub Main()
        Dim filePath As String = "C:\StackOverflow\tabSeperatedFile.txt"
        Dim FileContents As String()


        Console.WriteLine("Reading file contents")
        Using fleStream As StreamReader = New StreamReader(IO.File.Open(filePath, FileMode.Open, FileAccess.Read))
            FileContents = fleStream.ReadToEnd.Split(CChar(vbTab))
        End Using

        Console.WriteLine("Sorting Entries")
        Dim TotalWork As Decimal = CDec(FileContents.Count)
        Dim currentLine As Decimal = 0D

        For Each entry As String In FileContents
            'Do something with the file contents

            currentLine += 1D
            Dim progress = CDec((currentLine / TotalWork) * 100)

            Console.SetCursorPosition(0I, Console.CursorTop)
            Console.Write(progress.ToString("00.00") & " %")
        Next

        Console.WriteLine()
        Console.WriteLine("Finished.")
        Console.ReadLine()

    End Sub
End Module
