如何在vb.net中通过代码或命令进行击键

Imports System.Windows.Forms

' 模拟按下Ctrl+C组合键
SendKeys.Send("^c")

' 模拟按下Enter键
SendKeys.Send("{ENTER}")

Imports System.Runtime.InteropServices

Public Class Form1
    ' 导入user32.dll库
    <DllImport("user32.dll", CharSet:=CharSet.Auto, SetLastError:=True)>
    Private Shared Function SendMessage(ByVal hWnd As IntPtr, ByVal Msg As UInteger, ByVal wParam As IntPtr, ByVal lParam As IntPtr) As IntPtr
    End Function

    ' 定义常量
    Private Const WM_KEYDOWN As Integer = &H100
    Private Const WM_KEYUP As Integer = &H101

    ' 模拟按下Ctrl+C组合键
    Private Sub SimulateKeyPress()
        Dim hWnd As IntPtr = Me.Handle
        Dim keyCode As Integer = Keys.C
        Dim scanCode As Integer = MapVirtualKey(keyCode, 0)

        ' 按下Ctrl键
        SendMessage(hWnd, WM_KEYDOWN, Keys.ControlKey, 0)

        ' 按下C键
        SendMessage(hWnd, WM_KEYDOWN, Keys.C, 0)

        ' 释放C键
        SendMessage(hWnd, WM_KEYUP, Keys.C, 0)

        ' 释放Ctrl键
        SendMessage(hWnd, WM_KEYUP, Keys.ControlKey, 0)
    End Sub

    ' 辅助函数，将虚拟键码转换为扫描码
    Private Function MapVirtualKey(ByVal keyCode As Integer, ByVal mapType As Integer) As Integer
        Return SendMessage(Me.Handle, &H50, keyCode, mapType)
    End Function
End Class
