Question

First, I need to create a string array from a DataGridView.SelectedCells.Values. Then I need to append that string to itself, until a limit of member.count is reached. For example,
if

string [] = {"a", "b", "c"};  // Where abc are selectedCells.Values.

the new string [] should be:

{"a", "b", "c", "a", "b", "c", "a", "b"}

• if limit is 8, for example.

How could I solve this, please?

Answer 1

you can use the % (Modulus) in a for loop.

string[] oldArr = new string[3] {"a","b","c"};
string[] newArr = new string[8];
int limit = 8;
for ( int i = 0 ; i < limit ; i++ )
{
    newArr[i] = oldArr[i%oldArr.Length];
}

That’s it.
