First of all we will try for multiple field search with paging and sorting for products by using WebGrid.

Filter two lists on one property c# using linq. Ask Question Asked 5 years, 3 months ago. Active 5 years, 3 months ago. I have tried like this using linq:

LINQ query to filter the movies by selected genres. First, I added a filter for the selected genres (a string array) in Figure 2.
using System; using System.Linq; using System.Collections.Generic; var vals = new List<int> {-1, -3, 0, 1, 3, 2, 9, -4}; List<int> filtered = vals.Where(x => x > 0).ToList(); Console.WriteLine(string.Join(',', filtered)); The example filters out all positive values. List<int> filtered = vals.Where(x => x > 0).ToList();
void Main() { var projects = new List<Project> (); projects.Add (new Project { Name = "Project1", Tags = new int[] { 2, 5, 3, 1 } }); projects.Add (new Project { Name = "Project2", Tags = new int[] { 1, 4, 7 } }); projects.Add (new Project { Name = "Project3", Tags = new int[] { 1, 7, 12, 3 } }); var filteredTags = new int [] { 1, 3 }; var filteredProjects = projects.Where (p => p.Tags.Intersect (filteredTags).Count () == filteredTags.Length); } class Project { public string Name; public

class Person { prop string compositeKey { get; set; } } class Exclusions { prop string compositeKey { get; set; } } List<Person> people = GetFromDB; List<Exclusions> exclusions = GetFromOtherDB; List<Person> filteredResults = People - exclustions using the composite key as a comparer. I thought LINQ was the ideal way of doing this but after trying joins, extension methods, using yields, etc.
In this article. The following example shows how to sort lines of structured text, such as comma-separated values, by any field in the line. The field may be dynamically specified at runtime.
So we can use Linq Except to get those tags which are not included. Then we can use Count() == 0 to have only those which excluded no tags: var res = projects.Where(p => filteredTags.Except(p.Tags).Count() == 0);
using System; using System.Linq; using System.Collections.Generic; var vals = new List<int> {-1, -3, 0, 1, 3, 2, 9, -4}; List<int> filtered = vals.Where(x => x > 0).ToList(); Console.WriteLine(string.Join(',', filtered));
Filtering data: the Where() method, We already discussed how many LINQ methods can use a Lambda Expression to which will return true if the number is smaller than 10 and false if it's 10 or higher. We specify that the number has to be greater than 1, but not the specific have optimized your query to be as fast as possible, no matter how you wrote it. I am trying to experiment with lambda expressions, is there any other way we can write filter ( optional.filter(s -> (s.length() > 4)) ) This is complete working code: public class Main {
Using a Lambda Expression Over a List in C#, Lambda expression Sample code is also attached. following code checks whether all the people's ages are greater than Ten years or not:. A lambda expression consists of the lambda keyword followed by a comma seperated list of arguments and the expression to be evaluated using the list of arguments in the following format: Syntax Lambda arguments: expression. Return value: The value computed by substituting arguments in the expressions. Lambda expressions are often abbreviated by
How Stream.filter method works in Java 8, For example, if you have a stream of integral numbers that contains both even and Though filter() method is a little bit counter-intuitive, I mean, in order to create a From Collections to Streams in Java 8 Using the Lambda Expressions course just uses one filter() method to print Strings whose length is greater than 10. We can use Lambda function inside the filter() built-in function to find all the numbers divisible by 13 in the list. In Python, anonymous function means that a function is without a name. In Python, anonymous function means that a function is without a name.
How to filter a list in C# with lambda expression?, 1 Answer. LINQ expressions like Where return IEnumerable<T> . I usually capture the result with var but you could use ToList() to project the result to a list as well. Just depends what you need to do with the list later. Just depends what you need to do with the list later. List<Temp> tlistFiltered = tlist .Where(item => item.suburb == "brisbane") .ToList() Note that with the above you don't have to allocate a new list. The Where and ToList () methods both return a new sequence which you just need to capture with the reference. share.

Filtering with multiple filters MVC, I did find Filter/Search using Multiple Fields - ASP.NET MVC but it required me to change too much of my code because of variable issues for what I have already I am using ASP.NET MVC with EF 6.

I might filter by each option, one at a time or by combination of two or with all three. I was thinking of writing linq query for each and every options selected.
Filter/Search using Multiple Fields - ASP.NET MVC, I recommend you separate concerns and use an approach that the code in your controller be like this, simple, beautiful and extensible: Multiple filter stages. Interfaces for multiple filter stages can be implemented in a single class. For example, the ActionFilterAttribute class implements: Synchronous: IActionFilter and IResultFilter; Asynchronous: IAsyncActionFilter and IAsyncResultFilter; IOrderedFilter; Implement either the synchronous or the async version of a filter interface, not both. The runtime checks first to see if the filter implements the async interface, and if so, it calls that.

Error processing SSI fileLinq getting a list from another list, ToList(); Another option is to use a join, e.g. with a query expression: var query = from activeItem in activeItems join item in items on activeItem.Name equals item.Name select item; Note that this will give duplicate item values if there are multiple ActiveItem values with the same name. Here we again see one of the LINQ surprises (like Joda-speech which puts select at the end). However it is quite logical in this sense that it checks if at least one of the items (that is any) in a list (set, collection) matches a single value.
LINQ select List where sub-list contains item from another list, You can just use following LINQ expression: List1.Where(p => p.Cats.Any(c => List2.Any(c2 => c2.ID == c.ID)));.
