using linq: I have an object list of services
services[0]
id=1, name="rental", ...
services[1]
id=2. name="buy", ...
services[2]
id=3. name="both", ...
..etc
I have array[] contains what services to retrieve from the list selected[]=1,3
foreach(var service in services.where(x=>x.id.Contains(selected))
this is where I am stuck how do I add contains into where clause?
build error: contains operator not found
尝试在您的数组上使用Contains
而不是id
。
foreach(var service in services.where(x => selected.Contains(x.id))
