Using C# How can we check to see if a List of numbers has decreasing numbers?

Question

True: 1 , -2 , -3 ,-4
True: -3,-15,-20,-30

False ( this has a positive number) -4,2,-5,-7,-9....

According to your description, the following code might be useful:

        public static bool IsTrue(int[] array)   
        {  
            bool re = true;  
            for (int i = 0; i < array.Length-1; i++)  
            {  
                if (array[i] < array[i + 1])   
                {  
                    re = false;  
                    break;  
                }  
            }  
            return re;  
        }  

But the third example also seems to be True, which is decreasing.

Update:

        public static bool IsTrue(List<int> array)   
        {  
            bool re = true;  
            for (int i = 0; i < array.Count-1; i++)  
            {  
                if (array[i] < array[i + 1])   
                {  
                    re = false;  
                    break;  
                }  
            }  
            return re;  
        }
