Dealing with commas in a CSV file

Question

I am looking for suggestions on how to handle a csv file that is being created, then uploaded by our customers, and that may have a comma in a value, like a company name.

Add a reference to the Microsoft.VisualBasic (yes, it says VisualBasic but it works in C# just as well - remember that at the end it is all just IL).

Use the Microsoft.VisualBasic.FileIO.TextFieldParser class to parse CSV file Here is the sample code:

 Dim parser As TextFieldParser = New TextFieldParser("C:\mar0112.csv")
 parser.TextFieldType = FieldType.Delimited
 parser.SetDelimiters(",")      

   While Not parser.EndOfData         
      'Processing row             
      Dim fields() As String = parser.ReadFields         
      For Each field As String In fields             
         'TODO: Process field                   

      Next      
      parser.Close()
   End While
