推荐答案

我建​​议您在安装项目中创建一个自定义操作以覆盖OnBeforeUninstall()函数，然后在其中取消.遵循以下原则:

I would recommend creating a custom action in your setup project to override the OnBeforeUninstall() function, and cancel it in there. Something along these lines:

protected override void OnBeforeUninstall(IDictionary savedState)
{
     base.OnBeforeUninstall(savedState);
     if(Process.GetProcessesByName("nameOfYourProcess").Length > 0)
     {
          throw new InstallException("Cannot uninstall while appname is running.");
     }
}
