The error is on the following line:

Logger.n("Saving {0}", new object[]);

Thanks.

Hello and Welcome to Stack Overflow! It is quite simple actually: all you have to do is to declare the size of your array on the line you create and use it. Instead of new object[] you could try new object[32]. (or any size that helps you)

Hope this helps! ^^

You need to specify the size of the object array.

Try this:
Logger.n("Saving {0}", new object[10]);

Hello,

I am having issues creating a multidimensional array. In PHP I built this really nice function that will loop through an SQL query and return a 2-dimensional array of key name and values. In doing this I am able to extract my data like this:

echo $var[0][«field_name»];

However in C# I am having issues getting this to work.

I am trying to do it like this:

string[,] keyArray = new string[,];

but this is throwin an error:
CS1586: Array creation must have array size or array initializer.

The issue that I’ve been having is that I want to create a 2-D array but I dont know what the size will be when I’m done. Is it possible to create a completely empty 2-D array in C#?

If anyone is needing the PHP to see function here it is:

        function return_values($q)
       {
           $keyarr = array();

           for($i = 0; $i < mysql_num_rows($q); $i++)
           {
               $r = mysql_fetch_assoc($q);
               foreach($r as $key => $val)
               {
                   $keyarr[$i][$key] = $val;
               }
           }
           return($keyarr);
       }
