我创建了一个类，我在其中运行一个新进程（一个 CLI 外部应用程序），该应用程序有自己的进度条，所以我从隐藏的进程控制台中选择进度来计算控制台外的百分比，在我的班级中。
好吧，我想做的是在类中创建一个事件（或其他东西，一个事件只是我认为有用的第一个事件）以返回一个包含进度百分比的整数数字（百分比是一个从 0 到99)
我已经阅读了有关如何创建自定义事件的信息，但尝试它时我很迷茫，我不知道如何在我的类之外检索整数（变量百分比）以从其他类处理它，例如我运行一个方法来自我的班级，所以我想在默认的“Form1”类中处理进程百分比进度。
这是我的自定义类的代码：
Public Class CoreConverter
Public Shared Effects As String = String.Empty ' DSP Effects
' <summary>
' Gets or sets the CoreConverter executable path.
' </summary>
Public Shared CoreConverter_Location As String = ".\CoreConverter.exe"
Public Shared CoreConverter As New Process()
Public Shared CoreConverter_Info As New ProcessStartInfo() With { _
.CreateNoWindow = True, _
.UseShellExecute = False, _
.RedirectStandardOutput = True, _
.RedirectStandardError = True _
}
Public Shared Event Progress As EventHandler
Protected Sub OnProgress()
RaiseEvent Progress(Me, EventArgs.Empty)
End Sub
Public Shared Sub Run_CoreConverter()
CoreConverter_Info.FileName = CoreConverter_Location
CoreConverter_Info.StandardErrorEncoding = System.Text.Encoding.Unicode
CoreConverter_Info.StandardOutputEncoding = System.Text.Encoding.Unicode
CoreConverter.StartInfo = CoreConverter_Info
CoreConverter.Start()
Dim Percentage As Integer = 0
While Not CoreConverter.HasExited
If ChrW(CoreConverter.StandardOutput.Read) = "*" Then
Percentage += 1
RaiseEvent Progress(Nothing, EventArgs.Empty)
End If
End While
' MsgBox("end")
End Sub
End Class
这是来自 Form1 类的代码
Public Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Shown
AddHandler CoreConverter.Progress, AddressOf Process_Progress
CoreConverter.Run_CoreConverter(Arguments, blah blah blah)
End Sub
Protected Sub Process_Progress(sender As Object, e As EventArgs)
' MsgBox(e.ToString) ' I want to obtain the Integer percentage but don't know how to
End Sub
请注意，我需要使用 Addhandler 来处理 Progress 事件，但我真的想以其他方式处理它，但我做不到，我不知道为什么：
Public Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Shown
CoreConverter.Run_CoreConverter(Arguments, blah blah blah)
End Sub
Protected Sub Process_Progress(sender As Object, e As EventArgs) _
Handles CoreConverter.Progress
' MsgBox(e.ToString) ' I want to obtain the Integer percentage but don't know how to
End Sub
那么我能做些什么来解决这两个问题呢？
更新：
尝试使用@varocarbas 解决方案解决它...
核心转换器类：
Public Shared WithEvents p_progressBar As ProgressBar
Public Shared Sub Run_CoreConverter()
p_progressBar = New ProgressBar() With {.Maximum = 60}
CoreConverter_Info.FileName = CoreConverter_Location
CoreConverter.StartInfo = CoreConverter_Info
CoreConverter.Start()
While Not CoreConverter.HasExited
If ChrW(CoreConverter.StandardOutput.Read) = "*" Then
p_progressBar.PerformStep()
End If
End While
p_progressBar.Dispose()
CoreConverter.Close
End Sub
Form1类：
Public Sub Form1_Shown(sender As Object, e As EventArgs) Handles MyBase.Shown
' Exception: p_progressBar is not an event (of course, I know)
AddHandler CoreConverter.p_progressBar, AddressOf Process_Progress
CoreConverter.Run_CoreConverter(arguments, blah blah blah)
End Sub
Sub Process_Progress(sender As Object, e As EventArgs) ' Handles Coreconverter.p_progressBar obviouslly I can't do this... :(
MsgBox(sender.value)
End Sub
