Convert 2D List in 2D String Array C# [duplicate]

Question

I'm working with CSV but all the tutorials I've read use 2D Lists.

private void cargaCSV()
    {
        List<string[]> values = new List<string[]>();

        var reader = new StreamReader(File.OpenRead(*my file*));
        while (!reader.EndOfStream)
        {
            string line = reader.ReadLine();
            values.Add(line.Split(';'));
        }
    }

My problem is my project works with 2D String Array.

I tried the following:

    string [,]  Data = values.ToArray();

I want to convert the 2d list into 2d array

You're trying to get a [,]?

Do all lines have the same number of values?

If all the arrays have the same length, then you can do what you are doing and, after that, create and fill the array manually:

string[,] stringArray = new string[values.Count, values.First().Length]

for (int i = 0; i < values.Count; i++)
    row = values[i];
    for (int j = 0; j < row.Length; j++)
        string[i,j] = row[j];
    }
}

You don't have to typecast hard and old way.

Simply replace

string [,]  Data = values.ToArray();

With

var  Data = values.ToArray();

Now Data is two dimensional array of strings.
