First, what's the problem? did you simply read the MSDN help on it? -- would be too trivial.
Second, why would you use double.ToString? Chances are, you don't need it. It's always good to explain your goals, to get better answers.

in my application values are stored in database by conversion of double value to string.if double can be directly changed into string using tostring() then why split() is used.i want the usage of split used here.
b = a.ToString().Split("."C)

Hi,

see this sample:

VB

Dim a As Double = 123.23
Dim b As String() = Nothing
b = a.ToString().Split("."C)
Dim part1 As String = b(0)
Dim part2 As String = b(1)
MessageBox.Show(part1 + "  " + part2)

Basically in this case, split separates the part before and after the period, so that in b(0) you have "123" and in b(1) you have "23". Please take care of regional settings where 123.23 may be displayed as 123,23 (e.g. this is the case in Germany).

plz give the usage of split() here.

JF2015 17-Sep-12 6:47am

It is just to separate the part before and after the period.

Member 8953399 17-Sep-12 6:50am

this conversion of double to string can be done using tostring().but still why we require split().plz help

You don't need it. It may just be used if you want to have two separate strings. One before and one after the period.

plz dont mind bcz the code am analysing this code and in that split is used.

Dim avgBVsplit(2) As String
avgBVsplit = SumPC.ToString().Split(".")
If avgBVsplit.Count = 2 Then
If avgBVsplit(1).Length > 2 Then
frmRMM.tslPC.Text = "PC(Sum) : " + avgBVsplit(0) + "." + avgBVsplit(1).Substring(0, 2)
Else
frmRMM.tslPC.Text = "PC(Sum) : " + SumPC.ToString()
End If
Else
frmRMM.tslPC.Text = "PC(Sum) : " + SumPC.ToString()
End If
