Check if list contains any of another list

Question

I have a list of parameters like this:

public class parameter
{
    public string name {get; set;}
    public string paramtype {get; set;}
    public string          


        

Answer 1

If both the list are too big and when we use lamda expression then it will take a long time to fetch . Better to use linq in this case to fetch parameters list:

var items = (from x in parameters
                join y in myStrings on x.Source equals y
                select x)
            .ToList();
