I use this line for creating a Tuple array:
Tuple<String^, double>^ t = gcnew Tuple<String^, double>("a", 2.6);
But how can I create a multidimensional array?
E.g.:
t[][] = {
{"a", 2.6},
{"b", 7.1},
{"c", 2.4},
{"d", 2.7}
};
Even if we do that, how can I get elements inside of array, e.g.:
for (int i = 0; i < 4; i++){
textBox1->Text += t[i][0];
}
Use MSDN.
using namespace System;
int main()
{
const unsigned rank = 2;
const unsigned dim1 = 3;
const unsigned dim2 = 4;
auto arr = gcnew array<Tuple<String ^, double> ^, rank>(dim1, dim2);
for(int i = 0; i < dim1; i++)
for(int j = 0; j < dim2; j++)
arr[i, j] = gcnew Tuple<String ^, double>("@_@", i * j);
return 0;
}
rank is a dimensionality of array, so in this case it's a 2d array.
UPD
using aggregate initialization:
using elemT = Tuple<String ^, double>; // somewhere at top-level
//...
auto arr =
gcnew array<elemT ^, rank>{{gcnew elemT{"@_@", 1.}, gcnew elemT{"^_^", 2.}},
{gcnew elemT{"~_~", 3.}, gcnew elemT{"+_+", 4.}}};
UPD2
As the mystery unveiled, OP didn't need multidimensional arrays, just an array of tuples:
#include <iostream>
using namespace System;
using subarrT = array<double>;
using elemT = Tuple<String ^, String ^, subarrT ^>;
int main()
{
auto arr = gcnew array<elemT ^>{
gcnew elemT{"Name1", "Surname1", gcnew subarrT{29., 123., 10., 1230.}},
gcnew elemT{"Name2", "Surname2", gcnew subarrT{49., 32., 8., 256.}},
};
std::cout << static_cast<double>(arr[0]->Item3[1]) << std::endl; // 123.
return 0;
}
