我做了一个带有c＃的gui程序但是我想要即使人们双击
我的程序不止一次它只会打开一次
这样的东西可能会如何？

I made a gui program with c# but i want even if people double click my program more than once it would only open once
is something like that possible if it is how?

我已经用过这个课了，工作得很好..这是在vb.net，我希望这是

不是问题...

处理currentProcess = Process.GetCurrentProcess（）;

if（Process.GetProcessesByName（currentProcess.Proce ssName，
）
currentProcess.MachineName）.Length> 1）

{

Console.Write（已经在运行）;

控制台.Read（）;

}

currentProcess.MachineName).Length>1)
{
Console.Write("Already running");
Console.Read();

使用全局互斥锁识别正在运行的实例。

这样可以防止在机器范围内运行多个实例。


bool freeToRun;

string safeName =" Global \\StringUniquelyIdentifyingThisApplication" ;

使用（System.Threading.Mutex m = new System.Threading.Mutex（true，safeName

，out freeToRun））

{

if（freeToRun）

Application.Run（new MainForm（））;

MessageBox.Show（"已经在运行......） ;，safeName）;

}


威利。

Use a global mutex to identify your running instance.
This way you prevent running multiple instances machine wide.

bool freeToRun;
string safeName = "Global\\StringUniquelyIdentifyingThisApplication" ;
using(System.Threading.Mutex m = new System.Threading.Mutex(true, safeName
, out freeToRun))
{
if (freeToRun)
Application.Run (new MainForm());
MessageBox.Show("Already running...", safeName);
}
