如果您可以更改方法签名，请将其设置为返回 void 而不是 int 。

另一方面，如果你不能更改方法签名然后替换

If you can change the method signature the make it return void instead of int.
On the other hand, if you can't change the method signature then replace

返回objBGServices.DispatcherTimerSetup（httpClient，lati，longi，UserId）;

return objBGServices.DispatcherTimerSetup(httpClient, lati, longi, UserId);

with

with

objBGServices.DispatcherTimerSetup(httpClient, lati, longi, UserId);
return 0; // or whatever int value that makes sense
