方法1:
//直接砍 Process
System.Diagnostics.Process[] p = System.Diagnostics.Process.GetProcessesByName(Application.ProductName);
if (p.Length > 1)
{
for (int i = 0; i < p.Length; i++)
{
p[i].Kill();
}
}
方法2:
//宣告
[DllImport("kernel32.dll", EntryPoint = "CreateMutexA", SetLastError = true)]
public static extern IntPtr CreateMutex(IntPtr securityAttributes, bool initialOwner, string name);
[DllImport("kernel32.dll", EntryPoint = "ReleaseMutex", SetLastError = true)]
public static extern IntPtr ReleaseMutex(IntPtr handle);
public static bool IsMutexDataExist(string name)
{
bool returnValue = false;
int ERROR_ALREADY_EXISTS = 183;
IntPtr handle = CreateMutex(IntPtr.Zero, true, name);
if (Marshal.GetLastWin32Error() == ERROR_ALREADY_EXISTS)
{
returnValue = true;
}
ReleaseMutex(handle);
return returnValue;
}
//使用方法
if (IsMutexDataExist("BetWorldAuthServer") == true)
{
//MessageBox.Show("已經在執行中", Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Warning);
Environment.Exit(0);
