I'm getting some weird input in my VB.Net 2005 program. I am reading a .CSV file as input and parsing the fields. When I look at the raw file, there are no quotation marks in the file, however, when I parse an Address field, it places quotation marks around the value and I'm not sure why it's doing that. It does it for 3 other fields that basically contain city, state, zip. None of these values in the .CSV file have quotes around them. Here is the code I use to retrieve the data.

Code:
            Dim arrLine(16) As String
            F1 = System.IO.File.OpenText(Trim(txtTransmissionFileName.Text))

            Do While Not F1.EndOfStream
                strLine = F1.ReadLine

                arrLine = Split(strLine, ",")
                stcInput.custNO = Trim(arrLine(0))
                stcInput.custLocNO = Trim(arrLine(1))
                stcInput.invoiceNO = Trim(arrLine(2))
                stcInput.invoiceDate = Trim(arrLine(3))
                stcInput.truckID = Trim(arrLine(4))
                stcInput.transDateTime = Trim(arrLine(5))
                stcInput.custLocAddr = Trim(arrLine(6))
                stcInput.custLocCity = Trim(arrLine(7))
                stcInput.custLocState = Trim(arrLine(8))         
                stcInput.custLocZip = Trim(arrLine(9))
                stcInput.prodDesc = Trim(arrLine(10))      
                stcInput.gallons = Trim(arrLine(11))
                stcInput.prodPrice = Trim(arrLine(12))
                stcInput.taxPerGallon = Trim(arrLine(13))
                stcInput.transTotAmt = Trim(arrLine(14))
                stcInput.fedExciseTax = Trim(arrLine(15))
                stcInput.stateExciseTax = Trim(arrLine(16))
                stcInput.miscTaxes = Trim(arrLine(17))
                stcInput.salesTax = Trim(arrLine(18))
                stcInput.prodCD = Trim(arrLine(19))
            Loop
The lines in red are inserting quotation marks. Here is what the data looks like:

""12460 MAR VISTA DRIVE""
""DAYTON""
""OH""

""CLR CARB ULS #2""

Any ideas what is causing this?

Thanks,
