Question

I need to store string data in memory in the form of a table,
columns are fixed, but rows will be added to the end.

I guess I can use two dimensional string array string[][] if I had known the rows in advance, but that’s not the case.

I have currently created a custom class with 3 fields and stored them in a list, but I realise it not very graceful solution, the data will look like this

artist-name1, album-name1, filename1
artist-name2, album-name2,
filename2
artist-name3, album-name3, filename3
And so on..

Which data structure is best for this ?

Answer 1

You could use List<string[]> or List<List<string>>. First case will allow you to add as many rows as you want and the columns will be fixed. The second solution is somewhat more flexible and will let you add as many columns as you want.

List<string[]> list = new List<string[]>();
string[] row = new string[3];
row[0] = "artist-name1";
row[1] = "album-name1";
row[2] = "filename1";
list.Add(row);

Or

List<List<string>> list = new List<List<string>>();
List<string> row = new List<string>();
row.Add("artist-name1");
row.Add("album-name1");
row.Add("filename1");
list.Add(row);
