使用 C# 重新启动应用程序

Question

如何使用 C# 重新启动 WPF 应用程序？

Answer 1

I don't think there's a direct method in WPF like there is in WinForms. However, you could use methods from the Windowns.Form namespace like this: (You might need to add a reference to the System.Windows.Form assembly)

System.Windows.Forms.Application.Restart();

System.Windows.Application.Current.Shutdown();

Answer 2

The following is the best solution I found, you don't need to add a reference to System.Windows.Forms, instead you need add the namespace System.Diagnostics which you already has a reference to its assembly:

Process.Start(Application.ResourceAssembly.Location);
Application.Current.Shutdown();

Answer 3

The code

Process.Start(Application.ResourceAssembly.Location);

does not work for .NET Core 3.1 applications. Instead use

using System.Diagnostics;
using System.Windows;

...

Process.Start(Process.GetCurrentProcess().MainModule.FileName);
Application.Current.Shutdown();

This works also for .NET Framework applications.

You can use the Windows API Code Pack 's Restart and Recovery API. Just be aware that this is a new API, so it will only work on current operating systems (ie: Windows 7).
