I have a webform that is making a call to the Salesforce API and returning event records.  I am then looping thru the events as a test to spit out the values on the page.

I am getting the index out of bounds error.

See my code below.

The total number of event records is 7693.

Thanks for any help.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using SalesforceLibrary;
using SalesforceLibrary.sforce;

public partial class _Default : System.Web.UI.Page 
{
    private String username;
    private String password;
    private String sessionId;
    private String serverUrl;
    private SforceService proxy;
    private QueryResult qr = null;
    private String soql = "";
    
    protected void Page_Load(object sender, EventArgs e)
    {
        soql = "Select WhoId, Type, Subject From Event";

        proxy = new SforceService();
        if (Request.QueryString["sessionId"] != null)
        {
            sessionId = Request.QueryString["sessionId"].ToString();
            serverUrl = Request.QueryString["url"].ToString();
        }
        else
        {
            username = "xxxxxxx_xxxx@xxx.xxx";
            password = "xxxxxxxxx";
        }

        if (login())
        {
            qr = proxy.query(soql);

            if (qr.size > 0)
            {
                Response.Write("********************* " + qr.size);
                for (int i = 0; i <= qr.size; i++)
                {
                    Event ev = (Event)qr.records[i];
                    Response.Write("Event Name = " + ev.Who);
                    Response.Write("<br />");
                    Response.Write("Event Type = " + ev.Type);
                    Response.Write("<br />");
                    Response.Write("Event Subject = " + ev.Subject);
                    Response.Write("<br />");
                }
            }
            else
            {
                Response.Write("No Records returned.");
            }
        }
    }

    protected bool login()
    {
        if (sessionId != null)
        {
            try
            {
                proxy.Url = serverUrl;
                proxy.SessionHeaderValue = new SalesforceLibrary.sforce.SessionHeader();
                proxy.SessionHeaderValue.sessionId = sessionId;
            }
            catch (Exception ex)
            {
                Response.Write("Error logging in with session: " + ex.Message);
                return false;
            }
            return true;
        }
        else
        {
            SalesforceLibrary.sforce.LoginResult lr = proxy.login(username, password);

            if (!lr.passwordExpired)
            {
                proxy.Url = lr.serverUrl;
                proxy.SessionHeaderValue = new SalesforceLibrary.sforce.SessionHeader();
                proxy.SessionHeaderValue.sessionId = lr.sessionId;
            }
            else
            {
                Response.Write("Your password expired.");
                return false;
            }
            return true;
        }
    }

The index goes on the qr array.  Not sure about the rest, but this gets you the first "record" in the array, and casts it as an event.

             
       Event ev = (Event)qr[i].records[0];

i must less qr.size,because it start at 0
 for (int i = 0; i <= qr.size; i++)
==> for (int i = 0; i < qr.size; i++)
0

your for loop starts at zero and loops until it exceeds qr.size, you need to make it stop before it reaches qr.size as the array starts at zero so the last record returned will be qr.size - 1
change this :

for (int i = 0; i <= qr.size; i++)

to

for (int i = 0; i < qr.size; i++)
0

As jacko72 said, stop the for loop increment (i) before it reaches the qr.size (i < qr.size).
