Control another application using C#
提问by Salamander2007
I need to control other application by simulating mouse movement and keyboard input. How do I accomplish this in C#? Is it even possible?
我需要通过模拟鼠标移动和键盘输入来控制其他应用程序。我如何在 C# 中实现这一点？甚至有可能吗？

Have you looked at WhiteTestStack?
Sample code:
示例代码：
Application application = Application.Launch("foo.exe");
Window window = application.GetWindow("bar", InitializeOption.NoCache);
Button button = window.Get<Button>("save");
button.Click();
I don't think it can get better than that. The library is created by ThoughtWorks.
我认为没有比这更好的了。该库由 ThoughtWorks 创建。

Use the SendMessageNative Win32 API. DllImportthis method from the User32.dll. You can use this API to send both keyboard & mouse messages
使用SendMessage 本机 Win32 API。DllImport这个方法从 User32.dll 中导入。您可以使用此 API 发送键盘和鼠标消息

You can use p/invoke, I stole the following code for mouse clicks in random spots on a button with a known handle:
您可以使用 p/invoke，我窃取了以下代码，用于在具有已知句柄的按钮上的随机位置进行鼠标单击：
[Flags]
public enum MouseEventFlags
{
LEFTDOWN = 0x00000002,
LEFTUP = 0x00000004,
MIDDLEDOWN = 0x00000020,
MIDDLEUP = 0x00000040,
MOVE = 0x00000001,
ABSOLUTE = 0x00008000,
RIGHTDOWN = 0x00000008,
RIGHTUP = 0x00000010
}
[StructLayout(LayoutKind.Sequential)]
public struct Rectangle
{
public int X;
public int Y;
public int Width;
public int Height;
}
private static void Click(IntPtr Handle)
{
lock (typeof(MouseAction))
{
Rectangle buttonDesign;
GetWindowRect(Handle, out buttonDesign);
Random r = new Random();
int curX = 10 + buttonDesign.X + r.Next(100 - 20);
int curY = 10 + buttonDesign.Y + r.Next(60 - 20);
SetCursorPos(curX, curY);
//Mouse Right Down and Mouse Right Up
mouse_event((uint)MouseEventFlags.LEFTDOWN, curX, curY, 0, 0);
mouse_event((uint)MouseEventFlags.LEFTUP, curX, curY, 0, 0);
}
}
[DllImport("user32.dll")]
static extern bool SetCursorPos(int X, int Y);
[DllImport("user32.dll")]
private static extern void mouse_event(
long dwFlags, long dx, long dy, long cButtons, long dwExtraInfo);
[DllImport("user32.dll")]
static extern bool GetWindowRect(IntPtr hWnd, out Rectangle rect);

you can use AutoIT, it's freeware, and it has a dll version that you can import into C# (DllImport). It allows you to click on controls, write strings to edit boxes, make combobox selections etc on another application from C#.
您可以使用AutoIT，它是免费软件，并且有一个 dll 版本，您可以将其导入 C# (DllImport)。它允许您在 C# 中的另一个应用程序上单击控件、将字符串写入编辑框、进行组合框选择等。

I tried to do the same: to use the mouse i used this class
我尝试做同样的事情：为了使用鼠标，我使用了这个类
(you need to add using System.Runtime.InteropServices;)
（你需要添加using System.Runtime.InteropServices;）
public class MouseClick1 //public is important here**
{
[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);
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 int CoordX { get; set; }
public int CoordY { get; set; }
public void Click1()
{
Cursor.Position = new Point(CoordX, CoordY);
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
}
}
and after on your form1 (presuming the name is form1) you can
在你的form1之后（假设名称是form1）你可以
public partial class form1 : Form
{
MouseClick1 button1 = new MouseClick1();
MouseClick1 button2 = new MouseClick1();
[...]
[...]
public void Simulate_button1and2_Click(object sender, EventArgs e)
{
button1.CoordX = 1652; //random coordinates
button1.CoordY = 225;
button2.CoordX = 1650;
button2.CoordY = 250;
button1.Click1();
button1.Click2();
} }
} }
To have the coordinates on your pointer, I use a timer and a label:
为了在指针上显示坐标，我使用了一个计时器和一个标签：
private void timer1_Tick(object sender, EventArgs e)
{
Coord.Text = Cursor.Position.X.ToString() + " : " + Cursor.Position.Y.ToString(); //Premet d'avtheitroad les coord en direct
}
Work fine with me.
和我一起工作很好。
