c# - Should I create a new array or use array.clear? -

i have array of data gets zeroed out time time. that, should instantiate new array, or use array.clear method?

for instance,

int workingset = new int[5000];  // other code here  workingset = new int[5000]; // or array.clear(workingset, 0, 5000); 

when make new array instead of old one, c# will:

1. make old array eligible garbage collection, , deallocate it
2. allocate new array
3. fill new array zeros.

when keep old array, c# will

1. fill old array zeros.

everything else being equal, second approach more efficient.
