I am struggling to populate jagged array with chars My goal is to read string. slice them into chars, then populate jagged array with those chars
"Lorem",
5,
new char[][]
{
new char[] { 'L', 'o', 'r', 'e', 'm' },
},
or
"Loremipsumdolorsitamet",
5,
new char[][]
{
new char[] { 'L', 'o', 'r', 'e', 'm' },
new char[] { 'i', 'p', 's', 'u', 'm' },
new char[] { 'd', 'o', 'l', 'o', 'r' },
new char[] { 's', 'i', 't', 'a', 'm' },
new char[] { 'e', 't' },
},
like the example. above ints under the string represent arraySize(i.e. number of columns) and streamReader(see code under) is the string itself. I am using System.IO and System.Text
var read = streamReader.ReadToEnd().ToCharArray();
if (read.Length == 0)
{
return Array.Empty<char[]>();
}
char[][] jagArray = new char[read.Length / 5][];
for (int p = 0; p < read.Length; p )
{
for (int i = 0; i < read.Length / arraySize; i )
{
jagArray[i] = new char[arraySize];
for (int j = 0; j < arraySize; j )
{
jagArray[i][j] = read[p];
}
}
}
return jagArray;
I tried this code, but obviously it doesnt work.

Use this method to split a single char[]
array into array of arrays, each of which is no longer than cols
characters length:
public static char[][] ToJaggedArray(char[] chars, int cols)
{
int rows = (chars.Length cols - 1) / cols;
char[][] jagArray = new char[rows][];
for (int i = 0; i < rows; i )
{
jagArray[i] = new char[Math.Min(cols, chars.Length - cols * i)];
}
for (int i = 0; i < chars.Length; i )
{
int row = i / cols;
int col = i % cols;
jagArray[row][col] = chars[i];
}
return jagArray;
}

string str = "Loremipsumdolorsitamet";
int slice = 5;
List<List<char>> list = new List<List<char>>();
List<char> list2 = new List<char>();
int limit = str.Length/5 1;
for (int i = 0; i < limit; i )
{
if (str.Length <= 5)
{
slice = str.Length;
}
for (int j = 0; j < slice; j )
{
list2.Add(str[j]);
}
str = str.Remove(0, slice);
list.Add(list2);
list2 = new List<char>();
}
Hopefully I understood you correctly, This is my very scuffed way of doing it, hopefully some of the more experienced users can provide some info to improve this.
EDIT. OUTPUT:
foreach(var a in list)
{
foreach (var b in a)
{
Console.Write(b " ");
}
Console.WriteLine();
}
L o r e m
i p s u m
d o l o r
