With another process:
与另一个过程:
- Get the program path (e.g. via
Environment.CommandLine) - 获取程序路径(例如，通过Environment.CommandLine)
- Start a process with said path
- 使用该路径启动进程

Process p = new Process();
p.StartInfo.FileName = Application.ExecutablePath;
p.Start();
This is in winforms, but perhaps it's similar in WPF.
这是winforms (winforms)，但在WPF中可能类似。
