My SharePoint site having a Large List that contains large data
I have to fetch all items and show them in gridview?
I am using below code and getting the below error 

**"The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator"**

```
private void GetData()
    {
        using (SPSite site = new SPSite("URL"))
        {
            using (SPWeb web = site.OpenWeb())
            {
                SPList list = web.Lists.TryGetList("BulkData");

                if (list != null)
                {
                    SPQuery query = new SPQuery();
                    query.Query = "<Where><IsNotNull><FieldRef Name=\"Title\" /></IsNotNull></Where>";
                    query.QueryThrottleMode = SPQueryThrottleOption.Override;
                    SPListItemCollection items = list.GetItems(query);
                    int itemCount = items.Count;
                    StringBuilder sb = new StringBuilder();
                    string str1 = string.Empty;
                    foreach (SPListItem item in items)
                    {
                        int i = 1;
                        sb.Append("\r\n").Append(Convert.ToString(item["Title"])).Append("\r\n");
                        i++;
                    }
                    Log(sb);
                }
            }
        }
    }
