# EntityFrameworkCore.SqlServer.Extensions.Contains

## Installing via NuGet

```powershell

Install-Package EntityFrameworkCore.SqlServer.Extensions.Contains

```

## Example

Create a search model with 2 params

```csharp

public class CarSearch

{

   public int Id { get; set; }

   public string Model { get; set; }

}

var carSearchObjects = new List();

```

Your join would resemble something like this, which cant be done as the join would be between an in memory object list and a sql server table:

```csharp

from c in context.Cars

join o in carSearchObjects 

     on new { Id = c.Id, Model = c.Model } equals new { Id = o.Id, Model = o.Model }

select m;

```

## Usage

```csharp

using EntityFrameworkCore.SqlServer.Extensions.Contains;

using (var context = new DbContext())

{

    var carSearch = context.Cars.Take(800).Select(x => new { x.Model, x.Id }).ToList();

    var filtered = context.Cars.Contains(carSearch, "Cars", false, c => c.Model,  c => c.Id );

    Console.WriteLine(filtered.Count());

}

```
