Read and parse a CSV file into an array of rows and columns in C#

The following PopulateCsvIntoArraymethod used to read the CSV file into a two-dimensional array of strings.
I have included explanation of method lines, wherever needed. ///<summary> /// Populate the CSV file into an array, /// We assume that every line has the same number of fields and there may be blank lines. ///</summary> ///<returns></returns> privatestring[,] PopulateCsvIntoArray() { // Get path of CSV file. var path = Server.MapPath("~/Folder_Name/testfile.csv"); // Get the file's text using ReadAllText method. string fileData = System.IO.File.ReadAllText(path);
// Split CSV data into lines.     fileData = fileData.Replace('\n', '\r'); string[] lines = fileData.Split(newchar[] { '\r' }, StringSplitOptions.RemoveEmptyEntries);
// Get rows and columns counts. int totalRows = lines.Length;
