Question

到目前为止，我使用了1,2,3这样的串联Id字符串，并使用此查询在我的表格中进行了更新...

if exists( select ClientId from Clients where ClientId IN (SELECT i.items FROM dbo.Splitfn(@Id,',') AS i))
    begin
        update Clients set IsDeleted=1 where ClientId IN (SELECT i.items FROM dbo.Splitfn(@Id,',') AS i)
        select 'deleted' as message
    end

上述查询的linq-to-sql等价物是什么？任何建议......

如果我已经理解你正在尝试做的事情，那么这样的事情应该有效。

var idsToDelete = ids.Split(",").Select(x => Convert.ToInt32(x));

var clientsToDelete = _DB.Clients.Where(x => idsToDelete.Contains(x.Id));

foreach(var client in clientsToDelete)
{
   client.IsDeleted = true;
}

_DB.SubmitChanges();

Linq-To-Sql等效于此sql查询
