Filtering collection with LINQ

Question

Let\'s say we have a collection of Person objects

class Person 
{
     public string PersonName {get;set;}
     public string PersonAddress {get;set;}    
}
         


        

Answer 1

I would add a method to the Filter class to check if the filter is satisfied:

class Filter 
{
    public string FieldName {get;set;}
    public string FilterString {get;set;}

    public bool IsSatisfied(object o)
    { return o.GetType().GetProperty(FieldName).GetValue(o, null) as string == FilterString;
}

You can then use it like this:

var filtered_list = personsList.Where(p => userFilters.Any(f => f.IsSatisfied(p)));
