creating a default string in my string List

Question

So, I'm working with c# and I'm trying to create a Bar graph in the console using strings. So I created a 2D list and gave each slot a default "empty" image.

List<List<string>> chart = new List<List<string>>() {"| |"};

but when i wrote it out, i got these two error messages in Visual studios

Error   1   Argument 1: cannot convert from 'string' to 'System.Collections.Generic.List<string>'

Error   2   The best overloaded Add method 'System.Collections.Generic.List<System.Collections.Generic.List<string>>.Add(System.Collections.Generic.List<string>)' for the collection initializer has some invalid arguments

Probably what you are looking for is List<string> not List<List<String>> — Jenish Rabadiya

int[] levels = { 1, 4, 5, 2 }; Console.Write(string.Join("\r\n", Enumerable.Range(levels.Min(), levels.Max()).Reverse().Select(y => string.Join(" ", levels.Select(l => l >= y ? "|" : " "))))); — Biscuits

The right syntax is

List<List<string>> chart = new List<List<string>>() { new List<String>() { "| |" }};

since you're creating list of list of string (2D list as you've put it), not just list of string.

When u need to create default string in your List try this:

List<string> chart = new List<string>() {"| |"};

or if u need initialize default string in your List of List<string> try

List<List<string>> chart = new List<List<string>>() { new List<string> { "| |" } };

You need to add List as parameter

List<List<string>> chart = new List<List<string>>() { new List<string>{"| |","| |"}};
