Question

How would you split this row to a string array?

the problem is Rutois, a.s. , so you cannot directly split with ',' separator..

543472,"36743721","Rutois, a.s.","151","some name","01341",55,"112",1

thanks

You can use a regular expression to pick out the values from the line:

string line ="543472,\"36743721\",\"Rutois, a.s.\",\"151\",\"some name\",\"01341\",55,\"112\",1";
var values = Regex.Matches(line, "(?:\"(?<m>[^\"]*)\")|(?<m>[^,]+)");
foreach (Match value in values) {
  Console.WriteLine(value.Groups["m"].Value);
}

Output:

543472
36743721
Rutois, a.s.
151
some name
01341
55
112
1

This of course assumes that you actually have got the complete CSV record in the string. Note that values in a CSV record can contain line breaks, so getting the records from a CSV file can not be done by simply splitting it on line breaks.
