Using a loop to remove tabpages from my tabcontrol [EASY]

[Alex Dransfield]

Hi there

Basically, when a user logs out of my system I am trying to use a loop to loop through all the tabs in the tabcontrol and remove them, before adding the login tab back on there. Here's my code:

MessageBox.Show(Convert.ToString(tabControl1.TabCount));
            for (int i = 0; i <= tabControl1.TabCount; i++)
            {
                tabControl1.TabPages.RemoveAt(i);
            }
            logoutlabel.Visible = false;
            FirstLogin();

Basically, I am using the messagebox to check the number of tabs (Just to make sure I'm not going insane) and then I loop through the tabs attempting to remove them.

I get the "index [number] is out of range". Sometimes it'll remove the last two tabs, sometimes it'll just error straight away. I'm not sure what I'm doing wrong here. Please help me out!

Revised it! Silly me, I didn't think that after index 0 has been removed, the previous index 1 becomes the new index 0!

This code fixes it.

MessageBox.Show(Convert.ToString(tabControl1.TabCount));
            for (int i = tabControl1.TabCount-1; i >=0; i--)
            {
                tabControl1.TabPages.RemoveAt(i);
            }
            logoutlabel.Visible = false;
            FirstLogin();

why not just clear tabs, if you want to delete all of them?

tabControl1.TabPages.Clear();
