如何检查应用程序的另一个实例是否正在运行

要解决您的需求，您可以使用以下任一方法:if (System.Diagnostics.Process.GetProcessesByName(System.IO.Path.GetFileNameWithoutExtension(System.Reflection.Assembly.GetEntryAssembly().Location)).Count() > 1) return;从您的 Main 方法退出该方法...或if (System.Diagnostics.Process.GetProcessesByName(System.IO.Path.GetFileNameWithoutExtension(System.Reflection.Assembly.GetEntryAssembly().Location)).Count() > 1) System.Diagnostics.Process.GetCurrentProcess().Kill();这将立即终止当前加载进程.您需要为 System.Core.dll 的引用">.Count() 扩展方法.或者，您可以使用 .Length 属性.Could someone show how it is possible to check whether another instance of the program (e.g. test.exe) is running and if so stop the application from loading if there is an existing instance of it. 解决方案 Want some serious code? Here it is. var exists = System.Diagnostics.Process.GetProcessesByName(System.IO.Path.GetFileNameWithoutExtension(System.Reflection.Assembly.GetEntryAssembly().Location)).Count() > 1;This works for any application (any name) and will become true if there is another instance running of the same application.Edit: To fix your needs you can use either of these:if (System.Diagnostics.Process.GetProcessesByName(System.IO.Path.GetFileNameWithoutExtension(System.Reflection.Assembly.GetEntryAssembly().Location)).Count() > 1) return;from your Main method to quit the method... ORif (System.Diagnostics.Process.GetProcessesByName(System.IO.Path.GetFileNameWithoutExtension(System.Reflection.Assembly.GetEntryAssembly().Location)).Count() > 1) System.Diagnostics.Process.GetCurrentProcess().Kill();which will kill the currently loading process instantly.You need to add a reference to System.Core.dll for the .Count() extension method. Alternatively, you can use the .Length property. 这篇关于如何检查应用程序的另一个实例是否正在运行的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
