Queue<T>.CopyTo(T, Int32) Method is used to copy the Queue elements to an existing one-dimensional Array, starting at the specified array index. The elements are copied to the Array in the same order in which the enumerator iterates through the Queue and this method is an O(n) operation, where n is Count. This method comes under
public void CopyTo (T array, int arrayIndex);
array: It is the one-dimensional Array which is the destination of the elements copied from Queue<T>. The Array must have zero-based indexing.
arrayIndex: It is the zero-based index in array at which copying begins.
- ArgumentNullException: If the array is null.
- ArgumentOutOfRangeException: If the index is less than zero.
- ArgumentException: If the number of elements in the source Queue<T> is greater than the available space from arrayIndex to the end of the destination array.
Below programs illustrate the use of the above-discussed method:
Before Method: Queue Contains: A B C D Array Contains: arr : HTML arr : PHP arr : Java arr : Python arr : C# arr : OS After Method: Queue Contains: A B C D Array Contains: arr : HTML arr : PHP arr : A arr : B arr : C arr : D
System.IndexOutOfRangeException: Index was outside the bounds of the array.
