VB.net将字符串转换为具有高价值的整数

Question

I am using VB.net I Need Help what I want is for it to convert the string to integer as shown.

    Dim txt12(7) As String

    Dim txt12toint As Integer
    txt12(0) = "048048048048"
    If txt12(0).Substring(0, 1) = 0 Then
        txt12(0) = txt12(0).Substring(1, 11)
    End If
    txt12toint = Convert.ToInt64(txt12(0))

However there is always a message stating : OverflowException was unhandled arithmetic operation resulted in an overflow Makesure you are not dividing by zero

I even tried:

Cint(txt12(0))

and

Convert.toint32(txt12(0))

but the error to this is the characters are either too long or too short. because int32 is up to 2,147,483,647 one Please if anyone can help thank you in advance

Answer 1

Just declare txt12toint as Long:

Dim txt12toint As Long

This is because 48048048048 exceeds the maximum value for an Integer.
