C#用mouse_event模拟滑鼠點選的問題

1、首先添加using System.Runtime.InteropServices;

1 2 3 4 5 6 7 8

private readonly int MOUSEEVENTF_LEFTDOWN = 0x0002; //模拟滑鼠移動 private readonly int MOUSEEVENTF_MOVE = 0x0001; //模拟滑鼠左鍵按下 private readonly int MOUSEEVENTF_LEFTUP = 0x0004; //模拟滑鼠左鍵擡起 private readonly int MOUSEEVENTF_ABSOLUTE = 0x8000; //滑鼠絕對位置 private readonlyint MOUSEEVENTF_RIGHTDOWN = 0x0008;  //模拟滑鼠右鍵按下  private readonlyint MOUSEEVENTF_RIGHTUP = 0x0010;  //模拟滑鼠右鍵擡起  private readonlyint MOUSEEVENTF_MIDDLEDOWN = 0x0020;  //模拟滑鼠中鍵按下  private readonlyint MOUSEEVENTF_MIDDLEUP = 0x0040; // 模拟滑鼠中鍵擡起

public static extern void mouse_event( int dwFlags,  int dx,  int dy,  int dwData,  int dwExtraInfo); private void button2_Click( object sender, EventArgs e)        {             int x =  int .Parse(textBox1.Text);             int y =  int .Parse(textBox2.Text); //絕對位置            mouse_event(MOUSEEVENTF_MOVE | MOUSEEVENTF_ABSOLUTE, x * 65535 / 1600, y * 65535 / 900, 0, 0);//移動到需要點選的位置            mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_ABSOLUTE, x * 65535 / 1600, y * 65535 / 900, 0, 0);//點選            mouse_event(MOUSEEVENTF_LEFTUP | MOUSEEVENTF_ABSOLUTE, x * 65535 / 1600, y * 65535 / 900, 0, 0);//擡起 //相對位置  指的是相對于目前滑鼠的相對位置 mouse_event(MOUSEEVENTF_MOVE , x , y, 0, 0); //移動            mouse_event(MOUSEEVENTF_LEFTDOWN , x , y, 0, 0);//點選            mouse_event(MOUSEEVENTF_LEFTUP , x , y , 0, 0);//擡起 }
