DSAPI.文件.CMD命令行进程代理，是用来和CMD.exe或指定exe进行输出重定向的简化使用工具，可隐藏或显式地启动一个cmd.exe，并将输出流、输入流和错误流重定向至代理，通过事件触发方式与之交互。

相关代码如下：

Private WithEvents CMD命令行 As New DSAPI.文件.CMD命令行进程代理
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        CMD命令行.启动CMD命令行进程()
    End Sub
    Private Sub CMD命令行进程_有输出内容(Sender As CMD命令行进程代理, 输出内容 As String) Handles CMD命令行.有输出内容, CMD命令行.有输出报错内容
        Me.BeginInvoke(New SetText(AddressOf SetTextA), 输出内容)
    End Sub
    Private Sub Form1_FormClosing(sender As Object, e As FormClosingEventArgs) Handles Me.FormClosing
        CMD命令行.退出进程()
    End Sub


    Private Delegate Sub SetText(S As String)
    Private Sub SetTextA(S As String)
        TextBox2.Text &= S
        TextBox2.SelectionStart = TextBox2.TextLength
        TextBox2.ScrollToCaret()
    End Sub


    Private Sub TextBox1_KeyDown(sender As Object, e As KeyEventArgs) Handles TextBox1.KeyDown
        Select Case e.KeyValue
            Case Keys.Enter, Keys.Return
                CMD命令行.输入(TextBox1.Text)
                TextBox1.Clear()
                Exit Sub
        End Select
    End Sub
