Question

I am making a program that stores data in a 2D array. I would like to be able to delete rows from this array. I cannot figure out why this code doesn’t work:

for (int n = index; n < a.GetUpperBound(1); ++n)
{
     for (int i = 0; i < a.GetUpperBound(0); ++i)
     {
         a[i, n] = a[i, n + 1];
     }
}

Could someone please help me out? I would like it to delete a single row and shuffle all the rows below it up one place. Thankyou!

Answer 1

you need to create a new array if you want to delete an item

try something like this

var arrayUpdated = new string[a.GetUpperBound(1)][a.GetUpperBound(0)-1];
for (int n = index; n < a.GetUpperBound(1); n++)
{
     for (int i = 0; i < a.GetUpperBound(0); i++)
     {
         arrayUpdated [i, n] = a[i, 1];
     }
}
