一个可执行的preventing多个流程实例 [英] Preventing multiple process instances of a single executable
问题描述
我使用.NET与C＃。
I am using .NET with C#.
我想prevent相同的可执行文件在同一时间运行两个实例，但我不想prevent从另一个文件夹中运行相同的过程。
I want to prevent two instances of the same executable to run at the same time, but I don't want to prevent the same process that is run from another folder.
例如，我有一个可执行文件，是在两个不同的地点：
For example, I have an executable that is in two different locations:
-
C：\ MyProject的\主\ Program.exe文件
C:\MyProject\Master\Program.exe
C：\ MyProject的\从\ Program.exe文件
C:\MyProject\Slave\Program.exe
这些是相同的。exe文件，但在两个不同的位置。
These are the same .exe files, but in two different locations.
我想允许Program.exe文件的一个实例是从主文件夹，从文件夹从一个实例运行，但没有两个中的任何。
I want to allow one instance of Program.exe that is run from Master folder and one instance from the Slave folder, but no two of any.
我试图通过检查所有具有相同的名称（Process.GetProcessesByName）进程的数目要做到这一点，但我无法区别这两个。
I've tried to do this by checking the number of processes that have the same name (Process.GetProcessesByName), but then I can't differ the two.
我已经找到了最接近的是从过程得到的模块。
The closest I have found is to get the Modules from the Process.
第一个列表中的exe文件的ProcessModule。但我不知道这是否会永远是第一个就行了。有没有保证的，或者是有给解释问题更好的解决方案？
The first one in the list is ProcessModule of the exe. But I am not sure if this will always be the first one on the list. Is there any guarantee for that, or is there a better solution to the explained problem?
推荐答案
我会用一个全局互斥锁，而不是依赖于程序集名称。另一应用可以是使用例如相同的文件名。
I would use a global mutex instead of relying on the assembly name. Another application may be using the same file name for example.
请参阅例如这样的回答： <一href="http://stackoverflow.com/questions/819773/run-single-instance-of-an-application-using-mutex">Run使用互斥
See e.g. this answer: Run single instance of an application using Mutex
