c# - Filter list of objects based on condition -

public class car  {     public string name {get;set;}     public string color {get;set;} }  car1 = new {"ford", "white"} car2 = new {"ford fiesta", "blue"} car3 = new {"honda city", "yellow"} car4 = new {"honda", "white"}  var carobj = new list<car>();  carobj.add(car1); carobj.add(car2); carobj.add(car3); carobj.add(car4); 

i need filter output based on car names, if name subset of names present, remove them.

output:

car2 = new {"ford fiesta", "blue"} car3 = new {"honda city", "yellow"} 

here writing this, not giving me desired output.

// remove duplicare records. var carobjnew = new list<car>(); carobjnew = carobj;  carobj.removeall(a => carobjnew.any(b => a.name.contains(b.name))); 

any on how fix this.

as pointed out in comment have simple mistake. need remove item if list has item contains first item substring:

carobj.removeall(a => carobj.any(b => b.name.tolower().contains(a.name.tolower()) && b.name.length > a.name.length)); 

if want compare stringcomparison, swap contains indexof(string value, stringcomparison comparisontype) > 0
