You can't actually remove an element from an array, because arrays are a fixed size. However, you can create a new array which omits the old element:

public static T[] RemoveElement<T>(T[] original, int elementToRemove)
{
    T[] ret = new T[original.Length-1];
    Array.Copy(original, 0, ret, 0, elementToRemove);
    Array.Copy(original, elementToRemove+1, ret, elementToRemove,
               ret.Length - elementToRemove);
    return ret;
}

You can't remove items from an array. You can, however, create a new array without the item. Probably the most convenient (but not necessarily efficient) way would be via a list:

List<ParameterInfo> list = new List<ParameterInfo>(args);
list.RemoveAt(1);
args = list.ToArray();
