    "gender": "Male", 
    "children": [{ 
     "name": "Aron", 
     "gender": "Male"

    "gender": "Male", 
    "children": null 
}, { 
    "name": "Fred",

    }] 
}, { 
    "name": "Samantha",

     "gender": "Male" 
    }] 
}, {

は、私はあなたが私が私が

LINQ

使用してそれを行うことができますどのように知らせてもらえ

[{  
    "gender": "Male",   
     "name": "Jaime", 
     "gender": "Female" 
    }] 
}, 
{ 
    "name": "Fred", 
    "gender": "Male", 
    "children": [{ 
     "name": "Sam", 
     "gender": "Female" 
    }]

    "gender": "Female", 
    "children": [{ 
     "name": "Samantha", 
     "gender": "Female" 
    }] 
}] 

（以下同様）親の性別による女性の子供たちとグループを持っているのget親を必要とします編集

public class Parent 
{ 
    public int ParentID {get; set;} 
    public string Name {get; set;} 
    public string Gender {get; set;} 
    public List<Child> Children {get; set;} 
} 

public class Child 
{ 
    public int ChildID {get; set;} 
    public string Name {get; set;} 
    public string Gender {get; set;} 
    public DateTime DateOfBirth {get; set;} 
} 

そして私はリストのリストを持っていますシーン

var newlist = parents.where(p=> p.Children !=null && p.Children.Any(c=>  c.Gender=="Female")) 

編集 になります上記のJSONデータを持つ親、希望あなたは何として

[{  
    "gender": "Male", 
    "children": [{   
     "name": "Jaime"  
    }] 
}, 
{  
    "gender": "Female", 
    "children": [{ 
     "name": "Sam", 
     "name": "Samantha", 
    }] 
}]
