推荐答案

您需要为语句的else部分提供一个return 值.

You need to have a return value for the else part of the statement.

if ( ser.ConsultationClient(ID_CLIENT).Equals(0)){
retour rt = new retour(); 
rt.succes = 0;
rt.msgsucces = "opération réeussite";
return rt; 
}

else if (ser.ConsultationClient(ID_CLIENT).Equals(-1)){ 
retour ht = new retour();
ht.echec = -1;
ht.msgechec = "Operation échoué";
return ht; 
}
else
{
return null;//or some other value here;
}
