C#实现向mumu模拟器内粘贴文本

之前使用SendKeys.SendWait("asfasf");的方式向模拟器中发送文本,但是有可能存在输入法干扰的问题

现在使用新的思路,将要发送的文本放到剪切板中,然后通过粘贴的方法粘贴到模拟器中,但是测试了几个方法无法粘贴成功,只会向模拟器中打一个空格,但使用SendInput扫描码方式可以粘贴成功

public static class PasteHelperScanCode
{
/// <summary>
/// 对当前获得焦点的窗口/控件执行一次粘贴（Ctrl+V，扫描码方式）
/// 前提：焦点已在目标输入框，且剪贴板内容已准备好
/// </summary>
public static void PasteCtrlV(int keyDelayMs = 15)
{
// 左Ctrl: 0x1D，V: 0x2F（常用 Set 1 扫描码）
const ushort SCAN_LCTRL = 0x1D;
const ushort SCAN_V = 0x2F;

INPUT[] inputs =
{
KeyDownScan(SCAN_LCTRL),
KeyDownScan(SCAN_V),
KeyUpScan(SCAN_V),
KeyUpScan(SCAN_LCTRL),
};

// 可选：某些模拟器对按键时序敏感，适当加一点间隔更稳
if (keyDelayMs > 0)
{
// 拆分发送：确保时序（有些窗口对一次性批量包不敏感）
foreach (var i in inputs)
{
SendOrThrow(new[] { i });
Thread.Sleep(keyDelayMs);
}
}
else
{
// 不需要延迟就一次性发完
SendOrThrow(inputs);
}
}
