C# Clear array method help

Hi guys I am trying to clear a array

public static int[,] arrayname = new int[10, 10];

with this method.

Array.Clear(arrayname, 0, 0);


while (Controls.Count > 0)
{
Controls[0].Dispose();
}
InitializeComponent();
}

But the array is not being reset, any help is much appreciated

Just re-initialize it, garbage collector will clean the mess.

arrayname = new int[10, 10];

Isn't it the only way you have left? biggrin.gif (that is, besides manually resetting every element..)

I see no downsides apart from that for a while you'll have the array allocated twice in memory, but unless you're running on 256 kB RAM, you shouldn't have any problems.

The docs on this method say the last parameter is a length, so you want that last zero to be a 100?

Though in this case, the above is probably ok, just declaring a new one is likely "good enough" if this array isn't particularly memory intensive.

+1 to that.
That third parameter needs to be 100 in your case. Setting it to 0 causes nothing to happen.

I'm just a beginner, but perhaps this method:

for(int i = 0; i <= arraysize; i++) {
arrayname [ i ] = 0;
}

Good, but he has a 2D array, you'll need two of those, one into the other. Gets waay too slow and complicated..
