Build Lambda Expressions with Contains
问题 I have a problem converting simple linq query to Lambda Expression. My queries look like this: int[] array = List<int> array2 = sql.OfType<Table1>().Select(x=>x.ID).Take(10).ToList(); var result = sql.OfType<Table1>().Where(x => array.Contains(x.ID)).Take(10).ToList(); and the final result should be: static void DynamicSQLQuery<T>(IQueryable<T> sql, string fieldName) { List<int> array = sql.OfType<T>().Select(SelectExpression<T>(fieldName)).Take(10).ToList(); var result = sql.OfType<T>()
how can i store and reuse pieces of my lambda expressions
问题 I have a block of code where a piece of the lambda expression is used again and again. How can store this logic so that i can reuse this expression piece? Eg: lets take the example of the code given below Session.Query<DimensionGroup>()(dimgroup=>(dimgroup.Users.Where(map => ((map.User.Key == _users.PublicUser.Key || map.User.Key == _users.CurrentUser.Key) && map.AccessLevel.ToAccessLevel() == AccessLevel.Write)).Count() > 0)); (map.User.Key == _users.PublicUser.Key || map.User.Key == _users

How to assign values for a list of some objects defined as variable with Spring Expression Language(Or the other expression languages you aware of)
问题 In Spel, it is easy to assign some values for a List property. For example having object foo with a property defined as List, I usually do: SpelParserConfiguration config = new SpelParserConfiguration(true,true); ExpressionParser parser = new SpelExpressionParser(config); Foo foo = new Foo(); EvaluationContext context = new StandardEvaluationContext(foo); parser.parseExpression("barList[1].test='11111111'") .getValue(context); But what do you do for the case you want to assign values for a
