Im using array.GetLength() method in c#. Its asking for array dimension as a parameter.does it start at 1 or 0?

To find out the length of an array---> int l = array.length;

To find the last item of an array---> string last = somearray[somearray.Length-1];

You can use ArrayList. ArrayList will not check for errors at compile time.

To declare list---> ArrayList myList = new ArrayList();

To add something---->myList.Add(....);

then you can loop through an ArrayList like this:

foreach (object obj in myList)

{

if(obj is string)

{do this...)

else if(obj is DateTime)

{do this....}

else if(obj is bool)

{do this....}

else if(obj is Int)

{do this....}

else

{

// always have an else in case it falls through

throw new Exception();

}

}

Generic List is better choice--->List<Object> myObjectList = new List<Object>();

because array list will not throw an error at compile time, but generic list will because it checks for errors at compile time.

Length of an array starts at 0 index.

My suggestion is to use stack overflow where you can get answers pretty fast.

It would be 0.

An easier way is to just write:

length = array.Length;

Length gives you the total number of elements in the array. For a 1 dimensional array, Length and GetLength(0) are identical.
