ArrayList.AddRange(ICollection) Method is used to add the elements of an ICollection to the end of the ArrayList.
public virtual void AddRange (System.Collections.ICollection c);
Here, c is the ICollection whose elements should be added to the end of the ArrayList. The collection itself cannot be null, but it can contain elements that are null.
- ArgumentException: If c is null
- NotSupportedException: If the ArrayList is read-only or ArrayList has a fixed size.
Below programs illustrate the use of the above-discussed method:
