鼠标键盘方法定义：

if (sSave.IndexOf("2", 0) > -1)
{
SetCursorPos(200, 160);
return false;
}
return true;
}
测试输入英文字母：
private void btnKeyInput_Click(object sender, RoutedEventArgs e)
{
//英文输入
this.rtxt1.Focus();
//for (int i = 65; i < 91; i++) //A-Z
//{
// char Letter = (char)i;
// WinForm.SendKeys.SendWait(Letter.ToString());
// //SendKeys.Send(Letter.ToString());
// System.Threading.Thread.Sleep(100);
// WinForm.SendKeys.Flush();
//}
for (int i = 97; i < 123; i++)//a-z
{
char Letter = (char)i;
WinForm.SendKeys.SendWait(Letter.ToString());
//SendKeys.Send(Letter.ToString());
System.Threading.Thread.Sleep(100);
WinForm.SendKeys.Flush();
System.Threading.Thread.Sleep(100);
}
}
测试将字符串输入到文本文件：
private async Task ShowMessage(string msg)
{
await this.rtxt1.Dispatcher.BeginInvoke(new Action(() =>
{
rtxt1.AppendText($"{msg}\r\n");
rtxt1.ScrollToEnd();
}));
}
private async void btnMouse_Click(object sender, RoutedEventArgs e)
{
IntPtr h;
string strName = "键盘输入.txt - 记事本";
h = FindWindow(null, strName);
await ShowMessage($"窗口找到:{h}");
if (h.ToInt32() != 0)
{
SetForegroundWindow(h);
await ShowMessage($"窗口设置为顶层窗口");
SetCursorPos(300, 600);
await ShowMessage($"移到鼠标位置(300,600)");
mouse_event(MouseLeftDown | MouseLeftUp, 0, 0, 0, 0);
await ShowMessage($"单击");
await ShowMessage($@"输入字符串- D:\零基础学SQL.pdf");
WinForm.SendKeys.SendWait(@"D:\零基础学SQL.pdf");
System.Threading.Thread.Sleep(200);
SetCursorPos(750, 670);
mouse_event(MouseLeftDown | MouseLeftUp, 0, 0, 0, 0);
}
}
效果如下：
