like below fixes the issue
Could any one have any idea or any suggestions on how to refactor these things in more OO approach or generic way that would be very grateful to me.
var environmentCondition = new EnvironmentConditions
    ConditionType = spaceTypeInput.EnvironmentConditionsInput.ConditionType,
    CoolingSetPointOccupied = spaceTypeInput.EnvironmentConditionsInput.CoolingSetPointOccupied ?? 0,
    CoolingSetPointUnOccupied = spaceTypeInput.EnvironmentConditionsInput.CoolingSetPointUnOccupied ?? 0,
    HeatingSetPointOccupied = spaceTypeInput.EnvironmentConditionsInput.HeatingSetPointOccupied ?? 0,
    RelativeHumidityMax = spaceTypeInput.EnvironmentConditionsInput.RelativeHumidityMax ?? 0,
    RelativeHumidityMin = spaceTypeInput.EnvironmentConditionsInput.RelativeHumidityMin ?? 0
public class EnvironmentConditions
    public EnvironmentConditions(EnvironmentConditionsInput input)
        ConditionType = input.ConditionType;
        CoolingSetPointOccupied = input.CoolingSetPointOccupied ?? 0;
        CoolingSetPointUnOccupied = input.CoolingSetPointUnOccupied ?? 0;
        HeatingSetPointOccupied = input.HeatingSetPointOccupied ?? 0;
        RelativeHumidityMax = input.RelativeHumidityMax ?? 0;
        RelativeHumidityMin = input.RelativeHumidityMin ?? 0;
        // some new property
// new EnvironmentConditions(spaceTypeInput.EnvironmentConditionsInput);
public class SpaceTypeServices
    public Guid CreateRequest(...)
        // rest  
        var spaceType = new SpaceType(spaceTypeInput);
        return id;

How can I make this code more generic

Tag : chash , By : AdrianB

it should still fix some issue Make the interface generic, then use a Func as a selector for the key. This assumes that you want the key for the dictionary to be extracted from the node. If this isn't a hard requirement, then you could specify the key itself using the generic type specifier in the signature.
public interface ITopology<T>
    Dictionary<T, INode> Nodes { get; set; }  

public static class TopologyExtns 
    public static void AddNode<T>(this ITopology<T> topIf, INode node, Func<INode,T> keySelector ) 
        topIf.Nodes.Add( keySelector(node), node ); 
    public static INode FindNode<T>(this ITopology<T> topIf, T searchKey ) 
        return topIf.Nodes[searchKey]; 

public class TopologyImp<T> : ITopology<T> 
    public Dictionary<T, INode> Nodes { get; set; } 

    public TopologyImp() 
        Nodes = new Dictionary<T, INode>(); 
public interface INode<T>
     T Key { get; }
     string Name { get; set; }
     int ID { get; set; }

public class StringNode : INode<string>
    public string Key { get { return this.Name; } }
    public string Name { get; set; }
    public int ID { get; set; }

public interface ITopology<T> 
    Dictionary<T, INode<T>> Nodes { get; set; }   

public static class TopologyExtns  
    public static void AddNode<T>(this ITopology<T> topIf, INode<T> node )  
        topIf.Nodes.Add( node.Key, node );  
    public static INode<T> FindNode<T>(this ITopology<T> topIf, T searchKey )  
        return topIf.Nodes[searchKey];  

public class TopologyImp<T> : ITopology<T>  
    public Dictionary<T, INode<T>> Nodes { get; set; }  

    public TopologyImp()  
        Nodes = new Dictionary<T, INode<T>>();  
var topology = new TopologyImp<string>();
topology.AddNode( new StringNode { Name = "A", ID = 0 }  );
var node = topology.FindNode( "A" );

will be helpful for those in need I have a use case telling that when a tag is link and it's attributes are rel=dns-prefetch and prefetch then just say that pre resolving dns is enabled. , If you want to do this with Bs4 You could use this:
from bs4 import BeautifulSoup
soup = BeautifulSoup(html)  # Or some xml-like structure
# This will select all link tags which have a rel attribute with value dns-prefetch.
if len(soup.select('link[rel=dns-prefetch]')) > 0:
    self.pre_resolve_dns_enabled = True
if len(soup.select('link[rel=prefetch]')) > 0:
    self.prefetch_enabled = True

Is there a way to make the following code more generic?

To fix the issue you can do You could pass a function into the sum method to get the value from each line that you want to sum:
public int sumLines(Function<Line, Integer> extractor){
    Line[] lines = ...
    return Arrays.stream(lines).map(extractor)
        .filter(Objects::nonNull).mapToInt(i -> i).sum();
int time = sumLines(Line::getTime);

How to make this JSX code more generic to avoid code reuse in React?

will be helpful for those in need The code can be extracted to a component. In case some parameters are common in some cases, it can be higher-order component that accepts common parameters:
const boxHOC = (count, avg_length) => props => (
    <div className="box box-default">
        <div className="box-header with-border">
        <h3 className="box-title">Strings Info</h3>
        <div className="key-details">
            <dl className="dl-horizontal">
                <dt>Average Length</dt>
        <div className="box-header with-border">
            <h3 className="box-title">Strings</h3>

const OneTwoBox = boxHOC(1, 2);
const ThreeFourBox = boxHOC(3, 4);
