How can I split a C# string when a member of the array may consist of more than one word?

string makeModel = csvArray[0]; // or whichever column it is in
    string[] makeAndModel = makeModel.Split( new char[] { ' ' } , 2 );
    string make = makeAndModel[0];
    string model = makeAndModel[1];

,(?=([^"]*"[^"]*")*(?![^"]*"))

int numFields = 4;
string[] myFields = myLine.Split(' ');

int extraSpaces = myFields.length-numFields;
if(extraSpaces>0) {
  // Piece together element 0 in the array by adding the extra elements
  for(int n = 1; n <= extraSpaces; n++) {
    myFields[0] += ' ' + myFields[n];
  }
  // Move the other values back to elements 1, 2, and 3 of the array
  for(int n = 1; n < numFields; n++) {
    myFields[n] = myFields[n + extraSpaces];
    }
  }

MatchCollection m = RegEx.Matches(myLine, "^(.*) ([^ ]+) ([^ ]+) ([^ ]+)$");
 string MakeModel = m.Groups[1].Captures[0].ToString();
 string ModelYear = m.Groups[2].Captures[0].ToString();
 string Price     = m.Groups[3].Captures[0].ToString();
 string NumWheels = m.Groups[4].Captures[0].ToString();

string[] myFields = Microsoft.VisualBasic.Replace(myLine.Reverse(), " ", "_", 0, 3).Reverse().Split(' ');
myFields[0] = myFields[0].Replace("_", " "); //fix the underscores

String.Split(Convert.ToChar(","));
