回答1:

The TabControl exposes a SelectedIndex property, this will tell you the index of the currently visible tab within the TabControl.Items, simply Insert after that index. For example:

tabControl.Items.Insert(tabControl.SelectedIndex + 1, tabItem);

回答2:

TabItem tabItem = new TabItem();
tabItem.Header = "tab5";
tabControl1.Items.Insert(tabControl1.SelectedIndex + 1, tabItem);

回答3:

Use tabControl.Items.Insert(index, item)
