我已升级到Core 1.1和Visual Studio 2017.我正在运行一个简单的现有代码行来搜索用户输入字符串的列,但会收到错误...
InvalidOperationException:类型的变量'__searchTerm_1' 'scope.String'从范围''引用,但未定义
简而言之,我的守则是:
public IQueryable<SearchViewModel> ActivitySearch(string searchTerm)
{
var qry = (from act in context.Acts
.Include(x => x.ActivityExt)
select new SearchViewModel()
{
AMCNnumber = act.AMCNnumber
ActivityId = act.ActivityID,
ImplementingPartner = act.ActivityExt.imp,
ProjectTitle = act.Name,
Description = act.Description,
StartDate = act.StartDate,
EndDate = act.EndDate
});
if (!String.IsNullOrEmpty(searchTerm))
{
qry = qry.Where(x => x.AMCNnumber.Contains(searchTerm);
}
return qry.ToArray();
}
答案 0 :(得分:0)
事实证明,我遇到的子查询导致错误。我必须创建单独的变量来获取ID。
