List<T>.RemoveRange(Int32, Int32) Method is used to remove a range of elements from the List<T>.
Properties of List:
- It is different from the arrays. A list can be resized dynamically but arrays cannot.
- List class can accept null as a valid value for reference types and it also allows duplicate elements.
- If the Count becomes equals to Capacity then the capacity of the List increases automatically by reallocating the internal array. The existing elements will be copied to the new array before the addition of the new element.
public void RemoveRange (int index, int count);
index: It is the zero-based starting index of the range of elements which is to be removed.
count: It is the number of the elements which is to be removed.
- ArgumentOutOfRangeException: If the index is less than zero or Count is less than zero.
- ArgumentException: If the index and Count do not denote a valid range of elements in the List<T>.
