如何让我的应用程序单应用程序？ [英] How to make my app singleton application?

问题描述

我有一个应用程序，但目前它不是一个单独的应用程序。 我喜欢这样，它的另一个实例不会退出在运行时，使其单应用程序。

I have a application but currently it is not a singleton application. I like to make it singleton application so that its another instance does not exit at the run time .

如果可以做到这一点，请用一些样本codeS答复。

If this can be done please reply with some sample codes .

推荐答案

下面是一些很好的示例应用程序。下面是一种可能的方式。

Here are some good sample applications. Below is one possible way.

public static Process RunningInstance() 
{ 
    Process current = Process.GetCurrentProcess(); 
    Process[] processes = Process.GetProcessesByName (current.ProcessName); 

    //Loop through the running processes in with the same name 
    foreach (Process process in processes) 
    { 
        //Ignore the current process 
        if (process.Id != current.Id) 
        { 
            //Make sure that the process is running from the exe file. 
            if (Assembly.GetExecutingAssembly().Location.
                 Replace("/", "\\") == current.MainModule.FileName) 

            {  
                //Return the other process instance.  
                return process; 

            }  
        }  
    } 
    //No other instance was found, return null.  
    return null;  
}


if (MainForm.RunningInstance() != null)
{
    MessageBox.Show("Duplicate Instance");
    //TODO:
    //Your application logic for duplicate 
    //instances would go here.
}

许多其它可能的方法。见例子替代品。
