[System.Runtime.TargetedPatchingOptOut("Performance critical to inline across NGen image boundaries")]
void ICollection.CopyTo (Array array, int arrayIndex);
Parameters
array
Array Array

The one-dimensional Array that is the destination of the elements copied from ICollection. The Array must have zero-based indexing.

arrayIndex
Int32 Int32

The zero-based index in array at which copying begins.

Implements
Exceptions

array is multidimensional.

-or-

array does not have zero-based indexing.

-or-

The number of elements in the source ICollection is greater than the available space from arrayIndex to the end of the destination array.

-or-

The type of the source ICollection cannot be cast automatically to the type of the destination array.

Remarks

If the type of the source ICollection cannot be cast automatically to the type of the destination array, the nongeneric implementations of ICollection.CopyTo throw InvalidCastException, whereas the generic implementations throw ArgumentException.

This method is an O(n) operation, where n is Count.
