举个例子，我发现 某个地方 给你在过去。可能有一些帮助:

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
}

我已经结合了几个来源，以生成下面的代码，我目前正在使用。我也移除了窗户。表单引用，这样我就可以在控制台和 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;
}
}
}

有些控件(如 System.Windows.Forms 中的 Button)有一个“ PerformClick”方法来完成这项工作。

他们是一些需要，我不能看到穹顶的事情，像 凯斯或 Marcos Placona做，而不是只做

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");
}
}
}

我试过马科斯发布的代码但没用。不管我给 Y 坐标的是什么，光标都没有沿着 Y 轴移动。如果您希望光标的位置相对于桌面的左上角，而不是相对于您的应用程序，那么下面的代码可以工作。

    [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 函数来实际执行单击操作。 你可以给 X 和 Y 你想要的坐标，我使用文本框中的值:

            X = Convert.ToInt32(tbX.Text);
Y = Convert.ToInt32(tbY.Text);

Mouse.Click();

我使用 InvokeOnClick()方法。它有两个参数: Control 和 EventArgs。如果需要 EventArgs，那么创建它的一个实例并将其传入，否则使用 InvokeOnClick(controlToClick, null);。可以使用从 EventArgs 派生的各种与 Mouse 事件相关的参数，如 MouseEventArgs。
