Array.CopyTo Method (Array, Int64)
Copies all the elements of the current one-dimensional array to the specified one-dimensional array starting at the specified destination array index. The index is specified as a 64-bit integer.
Assembly: mscorlib (in mscorlib.dll)
array is null.
index is outside the range of valid indexes for array.
array is multidimensional.
The number of elements in the source array is greater than the available number of elements from index to the end of the destination array.
The type of the source Array cannot be cast automatically to the type of the destination array.
The source Array is multidimensional.
At least one element in the source Array cannot be cast to the type of destination array.
This method copies all the elements of the current array instance to the array destination array, starting at index index. The array destination array must already have been dimensioned and must have a sufficient number of elements to accommodate the copied elements. Otherwise, the method throws an exception.
If this method throws an exception while copying, the state of array is undefined.
This method is an O(n) operation, where n is Length.It performs a shallow copy only.
The following code example shows how to copy an Array to another Array with a nonzero lower bound. Note that the entire source Array is copied, including empty elements that overwrite existing elements in the target Array.
