How to combine two more List<> parameters?

I have five different for web service

List<_FiltA> A= new List<_FiltA>();          
List<_FiltB> B= new List<_FiltA>();         
List<_FiltC> C= new List<_FiltA>();   
List<_FiltD> D= new List<_FiltA>();          
List<_MainFilt> Main= new List<_MainFilt>();

and 4 different method and 1 [WebMethod] for each list's parameters For ex:

       [WebMethod]
           public List<_MainFilt> Search(string p1,int p2 ...)
            {
               Some code here...

             _FiltA= _FiltA(someParameters); //go to FiltA method
             _FiltB= _FiltB(someParameters);
                  .
                  .
                  some code...
                  .
                  .
              return Search;   //get Seach values
             }

           public List<_FiltA> FiltA (someParameters)
        {
           _FiltA FLG3 = new _FiltA();

             some codes....

              FLG3 = new _FiltA
                            {
                                PriceLink = Link,
                                Price = valueSomething,
                                Price2 = valueSomething1
                            };
                            Search.Add(FLG3);

           return FiltA ;

        }

And 3 more method like this.

I want to combined these 4 list (_ListA,_ListB,_ListC,_ListD) in List<_MainFilt> How can I combined? Or any suggestion for solving this problem?

You can just concatenate them.

public List<_MainFilt> Search(string p1,int p2 ...) {
    var result = _FiltA(someParameters)
        .Concat(_FiltB(someParameters))
        .Concat(_FiltC(someParameters))
        .Concat(_FiltD(someParameters))
        .ToList();
    // Do something with the list...
}

Instead of returning List<_MainFilt>, you could return an object containing the 4 lists of filters, e.g:

public class Filters
{
  public List<_FiltA> FilterA {get; set;}
  public List<_FiltB> FilterB {get; set;}
  public List<_FiltC> FilterC {get; set;}
  public List<_FiltD> FilterD {get; set;}
}

...

[WebMethod]
public Filters Search(string p1,int p2 ...)
{
  return new Filters {
    FilterA = _FiltA(someParameters),
    FilterB = _FiltB(someParameters),
    FilterC = _FiltC(someParameters),
    FilterD = _FiltD(someParameters),
  };
}
