我有以下LINQ查询
QueryResult<List<PersonDemographic>> members = new QueryResult<List<PersonDemographic>>();
var query = (from ms in this.Session.Query<MemberSummary>()
where ms.NameSearch.StartsWith(firstName.ToUpper())
&& ms.NameSearch2.StartsWith(lastName.ToUpper())
select new PersonDemographic
{
FirstName = ms.FirstName.ToProperCase(),
LastName = ms.LastName.ToProperCase(),
PersonId = ms.Id,
Address = new Address
{
Line1 = ms.AddressLine1.ToProperCase(),
Line2 = ms.AddressLine2.ToProperCase(),
City = ms.City.ToProperCase(),
State = ms.State,
Zipcode = ms.Zipcode,
},
PhoneNumber = new PhoneNumber
{
Number = string.IsNullOrWhiteSpace(ms.PhoneNumber) ? null : Regex.Replace(ms.PhoneNumber, @"(\d{3})(\d{3})(\d{4})", "$1-$2-$3")
}
});
if (this.Session.Transaction.IsActive)
{
members.Data = query.Distinct().Take(15).ToList();
}
else
{
using (var transaction = this.Session.BeginTransaction())
{
members.Data = query.Distinct().Take(15).ToList();
transaction.Commit();
}
}
代码在事务部分下运行。如果我没有区别使用它我没有问题。添加Distinct会给我一个例外
{“此SelectClauseVisitor不支持表达式类型10005。”}
我找不到任何确定的东西。有人可以帮忙吗?
谢谢, 保罗
