帖子里的问题解决了，但是代码变化一下，还是有问题，最后还是会多出个"AND"
情况1：
conditions.Add(new ConditionalCollections
ConditionalList = new List<KeyValuePair<WhereType, ConditionalModel>>
// 这里变成WhereType.Or，会输出：SELECT `Id`,`Email`,`UserType` FROM `AppUser` WHERE ( `Email` LIKE N'%aaa%' OR ( AND UserType = 1 ) )
new KeyValuePair<WhereType, ConditionalModel>(WhereType.Or, conditionUserType)
});
情况2：
var conditions = new List<IConditionalModel>();
// 把下面这句话注释掉，会输出 SELECT `Id`,`Email`,`UserType` FROM `AppUser` WHERE ( ( AND UserType = 1 ) )
// conditions.Add(conditionEmail);
conditions.Add(new ConditionalCollections
ConditionalList = new List<KeyValuePair<WhereType, ConditionalModel>>
new KeyValuePair<WhereType, ConditionalModel>(WhereType.And, conditionUserType)
