报下面的错误 :TjSell.TP2(string, int)”: 并非所有的代码路径都返回值 C:\Inetpub\wwwroot\DGWebSite\App_Code\TjSell.cs 大家看看是是么原因

[Red_angelX]

没有return

[shenjinglu]

把return放在外面

[-过客-]

把if和else if里的return tjsell;拿出来放在最后

[shenjinglu]

if (j == 0)
{
tjsell.zhuzhai = "0";
tjsell.bieshu = "0";
tjsell.bangong = "0";
tjsell.shangpu = "0";
}
OC.Connection.Close();
return tjsell;
