只运行一个应用程序的错误代码的分析

错误代码一

//单独单开exe的时候，是没有问题的
//此代码的问题在于，打开两个或多个独立的VS程序后，并且这些VS打开的项目的名字相同的话，会有多个进程主模块名字相同，但是进程ID不同的程序    导致无法启动实例【一个程序都打不开】
Process current = Process.GetCurrentProcess();
                Process[] processes = Process.GetProcessesByName(current.ProcessName);
                OperationLog.Instance.WriteLog(
                    string.Format("进程Id={2} 进程名字 = {0},进程主模块的名字 = {1}",
                    current.ProcessName, current.MainModule.FileName, current.Id),
                    LogType.UI);
                OperationLog.Instance.WriteLog(string.Format("进程名字={0}的进程数量 = {0}", processes.Length), LogType.UI);
                OperationLog.Instance.WriteLog(
                    string.Format("System.Reflection.Assembly.GetExecutingAssembly().Location.Replace(\"/\", \"\\\") = {0}", System.Reflection.Assembly.GetExecutingAssembly().Location.Replace("/", "\\")), 
                    LogType.UI);

                foreach (Process process in processes)
                {
                    OperationLog.Instance.WriteLog(
                        string.Format("process.Id = {0},process.MainModule.FileName = {1}", 
                        process.Id, process.MainModule.FileName),
                        LogType.UI);
                    if (process.Id != current.Id)
                    {
                        if (process.MainModule.FileName == current.MainModule.FileName)
                        {
                            return process;
                        }
                    }
                }

                return null;
            }

错误代码二

//只打开exe的话，没问题
//这个虽然解决错误代码一种关于多个VS程序，导致的不能运行程序的问题，【但是会导致，多个VS能打开多个程序】   并且调试运行处exe的时候，还可以从bin目录下直接打开exe
Process current = Process.GetCurrentProcess();
                Process[] processes = Process.GetProcessesByName(current.ProcessName);
                OperationLog.Instance.WriteLog(
                    string.Format("进程Id={2} 进程名字 = {0},进程主模块的名字 = {1}",
                    current.ProcessName, current.MainModule.FileName, current.Id),
                    LogType.UI);
                OperationLog.Instance.WriteLog(string.Format("进程名字={0}的进程数量 = {0}", processes.Length), LogType.UI);
                OperationLog.Instance.WriteLog(
                    string.Format("System.Reflection.Assembly.GetExecutingAssembly().Location.Replace(\"/\", \"\\\") = {0}", System.Reflection.Assembly.GetExecutingAssembly().Location.Replace("/", "\\")), 
                    LogType.UI);

                foreach (Process process in processes)
                {
                    OperationLog.Instance.WriteLog(
                        string.Format("process.Id = {0},process.MainModule.FileName = {1}", 
                        process.Id, process.MainModule.FileName),
                        LogType.UI);
                    if (process.Id != current.Id)
                    {
                        OperationLog.Instance.WriteLog(string.Format("System.Reflection.Assembly.GetExecutingAssembly().Location = {0}", 
                            System.Reflection.Assembly.GetExecutingAssembly().Location.Replace("/", "\\")), LogType.UI);
                        if (System.Reflection.Assembly.GetExecutingAssembly().Location.Replace("/", "\\") == current.MainModule.FileName)//只是区分了调试和非调试，能打开任意多个VS调试程序。并且还可以额外打开exe
                        {
                            return process;
                        }
                    }
                }
                OperationLog.Instance.WriteLog(string.Format("{0}",
                          Environment.NewLine+Environment.NewLine), LogType.UI);
                return null;
