“ newparticlesystem.startlifetime”已过时

Question

我对以下统一代码有疑问。

private ParticleSystem instantiate(ParticleSystem prefab, Vector3 position)
{
    ParticleSystem newParticleSystem = Instantiate(
      prefab,
      position,
      Quaternion.identity
    ) as ParticleSystem;

    // Make sure it will be destroyed
    Destroy(
      newParticleSystem.gameObject,
      newParticleSystem.startLifetime
    );

    return newParticleSystem;
}

在行

newparticlesystem.startlifetime 

我收到以下错误，我不明白。

"newparticlesystem.startlifetime" is obsolete 
 startlifetime property is deprecated.
