I'm trying to make an array that holds 6 strings in one row, and many other rows after that. This is my code:
string[, , , , , ,] conj = new string[,,,,,,] {
{"aimer", "aime", "aimes", "aime", "aimons", "aimez", "aiment"},
};
I'm getting the error "A nested array initializer is expected". I've never made an array this big before, and I couldn't find anything searching Google about why I'm getting this error and what I need to do to fix this.
Thanks for the help!
You are trying to initialize a multi-dimensional rectangular array (7 dimensions!).
So...
// 1D array containing 2 elements:
int[] r1d = { 1 , 2 , } ;
// 2x3 array containing 6 elements:
int[,] r2d = {
{ 1 , 2 , 3 , } ,
{ 4 , 5 , 6 , } ,
} ;
// a 2x3x4 array
int[,,] r3d = {
{
{ 1 , 2 , 3 , 4 , } ,
{ 5 , 6 , 7 , 8 , } ,
{ 9 , 10 , 11 , 12 , } ,
} ,
{
{ 13 , 14 , 15 , 16 , } ,
{ 17 , 18 , 19 , 20 , } ,
{ 21 , 22 , 23 , 24 , } ,
} ,
} ;
One might see a pattern developing here. You should be able to take it from here (hint: you're going to have curly braces nested 7 deep).
Note that each the initializers must all be of the same rank, lest the compiler get upset. For instance, if you say:
int[,,] r3d = {
{
{ 1 , 2 , 3 , 4 , } ,
{ 5 , 6 , 7 , 8 , } ,
{ 9 , 10 , 11 , 12 , } ,
} ,
{
{ 13 , 14 , 15 , 16 , } ,
{ 17 , 18 , 19 , 20 , } ,
//{ 21 , 22 , 23 , 24 , } ,
} ,
} ;
The compiler whines and says, An array initializer of length '3' is expected. That's because the initializer for x3d[0,1] the initializers are inconsistent.
a[x][y] is a jagged or sparse array, whilst b[x,y] is a rectangular or contiguous array. Strictly speaking, a[x][y] is an array of arrays. It has a fixed number of rows, but each row element a[x] is itself an array, allocated individually. Consequently, each row can have varying numbers of columns. a[x,y], on the other hand, is a single, contiguous, block of memory with a fixed number of rows and a fixed number of columns. The model, of course, extends to however many dimensions you give the array.Your array definition string[, , , , , ,] shouldn't have any commas. Do string[] instead.
An array [] is a list of things. What you had is called a rectangular array (although that definition may not longer apply with that many dimensions). With a simpler case: [,], (which really is a rectangular array) what you get is more analogous to a "grid" of items rather than a list.
