List(T).CopyTo Method (Int32, T, Int32, Int32)
Copies a range of elements from the List(T) to a compatible one-dimensional array, starting at the specified index of the target array.
Assembly: mscorlib (in mscorlib.dll)
- Type: T
- Type: System.Int32
The zero-based index in array at which copying begins.
- Type: System.Int32
The number of elements to copy.
array is a null reference (Nothing in Visual Basic).
index is less than 0.
arrayIndex is less than 0.
count is less than 0.
The number of elements from index to the end of the source List(T) is greater than the available space from arrayIndex to the end of the destination array.
The following example demonstrates all three overloads of the CopyTo method. A List(T) of strings is created and populated with 5 strings. An empty string array of 15 elements is created, and the CopyTo(T) method overload is used to copy all the elements of the list to the array beginning at the first element of the array. The CopyTo(T, Int32) method overload is used to copy all the elements of the list to the array beginning at array index 6 (leaving index 5 empty). Finally, the method overload is used to copy 3 elements from the list, beginning with index 2, to the array beginning at array index 12 (leaving index 11 empty). The contents of the array are then displayed.
