You are working with jagged array (i.e. array of array string[][]), not 2D one (which is string[,])
If you want to hardcode:
string[][] strA = new string[][] { // array of array
new string[] {"Hello", "World"}, // 1st line
new string[] {"Thanks", "Guys"}, // 2nd line
};
in case you want to provide x and y:
string[][] strA = Enumerable
.Range(0, y) // y lines
.Select(line => new string[x]) // each line - array of x items
.ToArray();
Finally, if we want to initialize strA without Linq but good all for loop (unlike 2d array, jagged array can contain inner arrays of different lengths):
// strA is array of size "y" os string arrays (i.e. we have "y" lines)
string[][] strA = new string[y][];
// each array within strA
for (int i = 0; i < y; ++i)
strA[i] = new string[x]; // is an array of size "x" (each line of "x" items)
Edit: Let's print out jagged array line after line:
Good old for loops
for (int i = 0; i < strA.Length; ++i) {
Console.WriteLine();
// please, note that each line can have its own length
string[] line = strA[i];
for (int j = 0; j < line.Length; ++j) {
Console.Write(line[j]); // or strA[i][j]
Console.Write(' '); // delimiter, let it be space
}
}
Compact code:
Console.Write(string.Join(Environment.newLine, strA
.Select(line => string.Join(" ", line))));
