code to avoid commas inside double quotes while reading csv files

Recently i was asked to read from a .csv file and populate metadata into sharepoint list items.There i stumbled upon a annoying thing that is values separated by commas inside double quotes which should be considered as asingle element
which means i had to write code to ignore values separeted commas inside double quotes and this is how did that.i hope it will help others and if somebody knows better way of doing it,then share the code with me as well

Here it is:
read line by line from csv file
  line = fs.ReadLine()

 Dim Array(30) As String
                Dim splitter() As Char = {","}
                Dim chars As Char() = line.ToCharArray()
                Dim j As Integer = 0

                Dim flag As Boolean = False
                Dim word As Char() = Nothing
                For i = 0 To chars.Length - 1
                    If Not flag Then
                        If chars(i) = ControlChars.Quote Then
                            flag = True
                            Continue For
                        End If
                        If chars(i) <> "," And i <> chars.Length - 1 Then
                            If Not flag Then
                                word += chars(i)
                            End If
                        ElseIf i = chars.Length - 1 Then
                            Try
                                word += chars(i)
                                Array(j) = word
                            Catch ex As Exception
                            End Try
                        Else
                            Try
                                Array(j) = word
                                word = Nothing
                            Catch ex As Exception

                            End Try
                            j += 1
                        End If
                    Else

                        If (i + 1) < chars.Length - 1 And chars(i + 1) <> ControlChars.Quote Then
                            word += chars(i)
                            Continue For
                        Else
                            If chars(i + 1) = ControlChars.Quote Then
                                word += chars(i)
                            End If
                            flag = False
                            i += 2
                        End If
                        Try
                            Array(j) = word
                            word = Nothing
                        Catch ex As Exception
                            'Array(j) = ""
                        End Try
                        j += 1
                    End If
                Next

After this start populating like   Dim names As String = Array(2) etc

thank you

Requiredfield validation on people picker

here are the few steps required for people picker validation in sharepoint.

1)press F12 and highlight the textarea of the people picker and copy the id
2)dont use (document.getElementById('<%= peoplepickerid.ClientID %>');) ,it wont work
3) then  create a javascript function


function callPostBack() {
       
        var a = document.getElementById('<%= ApprovingAuthorityPicker.ClientID %>'); //wont work

        var b=document.getElementById("ctl00_m_g_efabbd0f_b6f5_492c_92f8_18063b505623_ctl00_ApprovingAuthorityPicker_downlevelTextBox");
        if (b.value != "")
            return true;
        else
        {
        alert("Required field");
            return false;
    }

4)"ctl00_m_g_efabbd0f_b6f5_492c_92f8_18063b505623_ctl00_ApprovingAuthorityPicker_downlevelTextBox" is the copied id from step 1

5)call the javascript function on button click i,e

 <asp:Button ID="btnTopicSubmit" runat="server" Text="Save" OnClick="btnTopicSubmit_Click"  ValidationGroup="g2"
                                                CssClass="nav_newsmall" OnClientClick="return callPostBack();" />

6)check again and enjoy.

Thanks
