System.InvalidOperationException：没有与此对象关联的进程

Question

我正在调用带有代码的jar文件

Process process = new Process ();
process.StartInfo.FileName = "java";
process.StartInfo.Arguments = "-jar test.jar" + Filename;
process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
process.Start ();
process.WaitForExit ();

但仅在具有Windows 7的某些Windows上，可以正确调用该过程，但会出现异常

System.InvalidOperationException: No process associated with the object.
in System.Diagnostics.Process.EnsureState (State state)
in System.Diagnostics.Process.EnsureState (State state)
in System.Diagnostics.Process.GetProcessHandle (Int32 access, Boolean throwIfExited)
in System.Diagnostics.Process.WaitForExit (Int32 milliseconds)
in System.Diagnostics.Process.WaitForExit ()

在Windows 10上有效

也许是Windows上的补丁程序问题？

谢谢

尝试一下：

Process process = new Process ();
process.StartInfo.FileName = "java";
process.StartInfo.Arguments = "-jar test.jar " + Filename; //add space after .jar
process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
process.Start (); //process instead of Process
process.WaitForExit ();
