Question

var movieNext = new string[,]
{
    { "superhero", "action", "waltdisney", "bat"}, 
    {"superhero", "action", "marvel",""}, 
    {"history", "action", "malay", "" },
    {"malay", "novel", "", ""}, 
    {"history", "bat", "", ""}
};

The above code is a multidimensional array, which stores a sequence of movie’s keyword. Is there a way to implement this without having to put the blank strings in the array initialization?

For example you can see in the above code, I have to put the blank string “” to fill up the array.

Answer 1

You can consider C# jagged array (though they are different from multi-dimensional arrays).

string[][] movieNext =  {
new [] { "superhero", "action", "waltdisney", "bat"},
new []  {"superhero", "action", "marvel"}, <and so on>
};

If you want to stick with multi-dimensional arrays, you have to initialize the values individually. If you don’t provide any string value for any of the index (i,j) by default it will be null.
