C#: Replacing loops with LINQ
What would be the equivalent for these code samples in LINQ (C#):

    	int[] items = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
	
	int number = -1;
	foreach (int i in items) 
	{
		if (i == 5) 
		{
			number = i;
			break;
		}
	}


And how would you replace a for loop with two (or more) conditions in LINQ?
*(it is similar to the code above, couldn't come up with a better example. Imagine that other conditions or checks happen there in the for loop)*

    	int[] items = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
	
	int number = -1;
	
	for (int i = 0; i < items.Length && number == -1; i++) 
	{
		if (items[i] == 5)
			number = items[i];
	}


And the third piece of code, how would this be translated in LINQ:

    	List<int> items2 = new List<int>() { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
	
	int i = items2.Count - 1;
	
	for (; i > 0; i--)
		items2.RemoveAt(i);


Thanks in advance.
