在 C# 的 winforms 应用中,如何模拟鼠标点击?
我结合了几个来源,编写了下面的代码,目前正在使用。我还删除了Windows.Forms引用,以便在控制台和WPF应用程序中使用它而不需要额外的引用。
using System;
using System.Runtime.InteropServices;
public class MouseOperations
{
[Flags]
public enum MouseEventFlags
{
LeftDown = 0x00000002,
LeftUp = 0x00000004,
MiddleDown = 0x00000020,
MiddleUp = 0x00000040,
Move = 0x00000001,
Absolute = 0x00008000,
RightDown = 0x00000008,
RightUp = 0x00000010
}
[DllImport("user32.dll", EntryPoint = "SetCursorPos")]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool SetCursorPos(int x, int y);
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool GetCursorPos(out MousePoint lpMousePoint);
[DllImport("user32.dll")]
private static extern void mouse_event(int dwFlags, int dx, int dy, int dwData, int dwExtraInfo);
public static void SetCursorPosition(int x, int y)
{
SetCursorPos(x, y);
}
public static void SetCursorPosition(MousePoint point)
{
SetCursorPos(point.X, point.Y);
}
public static MousePoint GetCursorPosition()
{
MousePoint currentMousePoint;
var gotPoint = GetCursorPos(out currentMousePoint);
if (!gotPoint) { currentMousePoint = new MousePoint(0, 0); }
return currentMousePoint;
}
public static void MouseEvent(MouseEventFlags value)
{
MousePoint position = GetCursorPosition();
mouse_event
((int)value,
position.X,
position.Y,
0,
0)
;
}
[StructLayout(LayoutKind.Sequential)]
public struct MousePoint
{
public int X;
public int Y;
public MousePoint(int x, int y)
{
X = x;
Y = y;
}
}
}
1. SetCursorPos, 2. MouseEvent(LeftButtonDown), 3. SetCursorPos, 4. MouseEvent(LeftButtonUp)
。可能需要将其封装在一个辅助方法中。 - Michal Ciechan我在过去的某个地方找到了一个示例somewhere,这里可能会有所帮助:
using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;
public class Form1 : Form
{
[DllImport("user32.dll",CharSet=CharSet.Auto, CallingConvention=CallingConvention.StdCall)]
public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint cButtons, uint dwExtraInfo);
//Mouse actions
private const int MOUSEEVENTF_LEFTDOWN = 0x02;
private const int MOUSEEVENTF_LEFTUP = 0x04;
private const int MOUSEEVENTF_RIGHTDOWN = 0x08;
private const int MOUSEEVENTF_RIGHTUP = 0x10;
public Form1()
{
}
public void DoMouseClick()
{
//Call the imported function with the cursor's current position
uint X = (uint)Cursor.Position.X;
uint Y = (uint)Cursor.Position.Y;
mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, X, Y, 0, 0);
}
//...other code needed for the application
}
像 System.Windows.Forms
中的按钮(Button)这样的控件,具有“PerformClick”方法可以实现此功能。
Mouse.Click();
我尝试了马科斯发布的代码,但它对我没有起作用。无论我给Y坐标赋什么值,光标都不会在Y轴上移动。下面的代码可以工作,如果你想要相对于桌面左上角而不是相对于你的应用程序来获取光标位置。
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern void mouse_event(long dwFlags, long dx, long dy, long cButtons, long dwExtraInfo);
private const int MOUSEEVENTF_LEFTDOWN = 0x02;
private const int MOUSEEVENTF_LEFTUP = 0x04;
private const int MOUSEEVENTF_MOVE = 0x0001;
public void DoMouseClick()
{
X = Cursor.Position.X;
Y = Cursor.Position.Y;
//move to coordinates
pt = (Point)pc.ConvertFromString(X + "," + Y);
Cursor.Position = pt;
//perform click
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
}
我只使用mouse_event函数来实现点击操作。你可以给出你想要的X和Y坐标,我使用了文本框中的值:
X = Convert.ToInt32(tbX.Text);
Y = Convert.ToInt32(tbY.Text);
Cursor.Position
足以将鼠标光标定位到任何位置,然后使用 WIN32API 进行实际点击。 - Ge Rong我使用InvokeOnClick()
方法。它需要两个参数:Control和EventArgs。如果你需要EventArgs,那么创建一个实例并传入,否则使用InvokeOnClick(controlToClick, null);
。你可以使用从EventArgs派生的各种鼠标事件相关参数,例如MouseEventArgs。
有些需求我无法像Keith或Marcos Placona那样去完成,而不只是做到这一点。
using System;
using System.Windows.Forms;
namespace WFsimulateMouseClick
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
button1_Click(button1, new MouseEventArgs(System.Windows.Forms.MouseButtons.Left, 1, 1, 1, 1));
//by the way
//button1.PerformClick();
// and
//button1_Click(button1, new EventArgs());
// are the same
}
private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show("clicked");
}
}
}
NullReferenceException
