Using Lambda expression instead of For Each Loop in ASP.Net

Hi alibasha,

Please check the below example and modify your code.

VB.Net

    Private ASTERISK As Char = ","c
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
        Dim currentPolicyLob As String = "GeneralLiability,Property,Umbrella,Test,test1"
        Dim value As Boolean = DiamondScoreCheckForOdType(currentPolicyLob, "", DateTime.Now)
    End Sub

    Private Function DiamondScoreCheckForOdType(ByVal currentPolicyLob As String, ByVal predominantState As String, ByVal policyEffectiveDate As DateTime) As Boolean
        Dim listOfLobForDiamondScoreRule As HashSet(Of String) = New HashSet(Of String)() From {
                                         {"Auto"},{"AutoNonDealer"},{"Garage"},{"GeneralLiability"},{"InlandMarine"},{"PesticideHerbicide"},{"Property"},{"Umbrella"}}
        Dim lobList As List(Of String) = New List(Of String)()
        lobList = currentPolicyLob.Split(ASTERISK).ToList()
        ' Count without loop.
        Dim eligibleLobCheckCounter As Integer = lobList.Where(Function(t2) listOfLobForDiamondScoreRule.Any(Function(t1) t2.Contains(t1))).Count()

        If (eligibleLobCheckCounter > 0) Then
            Dim isStateAndEffDateEligible As Boolean = (New LobCO.Shared.COShared).IsStateRuleApplicable(getLineOfBusiness(Lob.LineOfBusiness.Common), predominantState,policyEffectiveDate,DiamondScoreRuleCheckForOdType)
            Return isStateAndEffDateEligible
        End If

        Return False
    End Function

C#

char ASTERISK = ',';
protected void Page_Load(object sender, EventArgs e)
{

    string currentPolicyLob = "GeneralLiability,Property,Umbrella,Test,test1";
    bool value = DiamondScoreCheckForOdType(currentPolicyLob, "", DateTime.Now);
}

private bool DiamondScoreCheckForOdType(string currentPolicyLob, string predominantState, DateTime policyEffectiveDate)
{
    HashSet<string> listOfLobForDiamondScoreRule = new HashSet<string>() {
                                                    { "Auto" },
                                                    { "AutoNonDealer" },
                                                    { "Garage" },
                                                    { "GeneralLiability" },
                                                    { "InlandMarine" },
                                                    { "PesticideHerbicide" },
                                                    { "Property" },
                                                    { "Umbrella" } };
    List<string> lobList = new List<string>();
    lobList = currentPolicyLob.Split(ASTERISK).ToList();
    // Count without loop.
    int eligibleLobCheckCounter = lobList.Where(t2 => listOfLobForDiamondScoreRule.Any(t1 => t2.Contains(t1))).Count();
    if ((eligibleLobCheckCounter > 0))
    {
        bool isStateAndEffDateEligible = (new LobCO.Shared.COShared()).IsStateRuleApplicable(getLineOfBusiness(Lob.LineOfBusiness.Common), predominantState, policyEffectiveDate, DiamondScoreRuleCheckForOdType);
        return isStateAndEffDateEligible;
    }

    return false;
