Parameters

array
Type: T

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

index
Type: SystemInt32

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

Implements

ICollectionTCopyTo(T, Int32)
Exceptions
ExceptionCondition
ArgumentNullException

array is .

ArgumentOutOfRangeException

index is less than zero.

ArgumentException

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

Remarks

This method uses ArrayCopy to copy the elements.

The elements are copied to the Array in the same order in which the enumerator iterates through the CollectionT.

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