I was trying to get all the error in the Visual Studio 2015 Error List window but I am getting an index out of bound exception while trying to access the ErrorItem through errors.Item(i) call. Am I missing any casting ?

EnvDTE80.DTE2 dte2 =  ServiceProvider.GetService(typeof(EnvDTE.DTE)) as DTE2);
ErrorItems errors = dte2.ToolWindows.ErrorList.ErrorItems;
for (int i = 0; i < errors.Count; i++)
{
    ErrorItem item = errors.Item(i);
}

The ErrorItems.Item method seems to need an absolute index, starting from 1, so change your loop to:

for (int i = 1; i <= errors.Count; i++)

Then it should work.

Well the .Count() Methods of all Lists or Arrays start at 1, while a Index in the IT world always will start at 0. So at the very end, your count will reach a number that won't be in your index.

So try the suggestion of BviLLe_Kid and subtract 1.

EDIT

Okay forget that. I think that was a brainlag. But I think deleting this answer won't be necessary since I can tell that BviLLe_Kid suggestion is wrong.

    static void Main(string[] args)
    {
        List<string> tmpList = new List<string>();
        for (int i = 0; i < 10; i++)
        {
            Debug.WriteLine("List Item No" + i);
            tmpList.Add("Item " + i);
        }
        Debug.WriteLine("_____________");
        Debug.WriteLine("List Count: " +tmpList.Count());
        Debug.WriteLine("_____________");
        for (int i = 0; i < tmpList.Count(); i++)
        {
                Debug.WriteLine(tmpList[i]);
        }
    }

Debug:

List Item No0

List Item No1

List Item No2

List Item No3

List Item No4

List Item No5

List Item No6

List Item No7

List Item No8

List Item No9

List Count: 10

Item 0

Item 1

Item 2

Item 3

Item 4

Item 5

Item 6

Item 7

Item 8

Item 9
