分享如何用C#关闭指定进程中的互斥体/关闭进程内指定句柄
想做个游戏多开器，找到互斥体之后不知道怎么用C#关闭这个句柄
private int GetProcessPorEx_ByProssName(string ProssName, ref List<Process> ProMult)
{
ProMult.Clear();
Process[] pp = Process.GetProcessesByName(ProssName);
for (int i = 0; i < pp.Length; i++)
{
ProMult.Add(pp[i]);
}
return ProMult.Count;
}
List<Process> Pro_Mult = new List<Process>();
private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show(GetProcessPorEx_ByProssName("JX3ClientX64", ref Pro_Mult).ToString());
foreach (Process pr in Pro_Mult)
{
// 互斥体 \Sessions\2\BaseNamedObjects\A5DFEC3F
// 线程内句柄为 1，要如何关闭这个句柄？
}
}

额，我当然知道是干嘛的，这个互斥体就是游戏防多开的，用别的工具关了确实也能多开，也没别的什么崩溃

你还知道是干什么的句柄吗？怎么能就随便说“关闭”二字？
