新手求教，这代码是什么意思？

public Vio[] GetVio(string hm, string name, string datetime, string sex, string num) {
            object[] results = this.Invoke("GetVio", new object[] {
                        hm,
                        name,
                        datetime,
                        sex,
                        num});
            return ((Vio[])(results[0]));
     }
