No, this doesn't exist. You have to remove the tab and re-add it when you want it. Or use a different (3rd-party) tab control.

使用TabControl中的TabPages属性的方法

public TabControl.TabPageCollection TabPages { get; }

第一个直接移除实例

第二个根据下标移除

第三个根据TabPage的名字来移除

 

第三个方法中的 key指的是："The Name property corresponds to the key for a TabPage in the TabControl.TabPageCollection.

 

 

public partial class Form1 : Form    {        private TabControl tabControl;        public Form1()        {            InitializeComponent();            LoadTabControl();            RemoveTabPges("tab");        }        private void LoadTabControl()        {            tabControl = new TabControl { Dock = DockStyle.Fill };            Controls.Add(tabControl);            LoadTabPages();        }        private void LoadTabPages()        {            if (tabControl == null)            {                throw new ArgumentNullException("tabControl", "tabControl can not be null");            }            TabPage tabPage;            tabPage = new TabPage { Text = "tabPage1",Name = "tab"};            tabControl.TabPages.Add(tabPage);            tabPage = new TabPage() { Text = "tabPage2" ,Name = "tab"};            tabControl.TabPages.Add(tabPage);            TabControl.TabPageCollection tabPageCollection = tabControl.TabPages;            foreach (var item in tabPageCollection)            {                Console.WriteLine();            }            if (tabPageCollection.ContainsKey("tab"))            {                Console.WriteLine("Exist");            }        }        private void RemoveTabPges(string key)        {            try            {                if (tabControl != null)                {                    tabControl.TabPages.RemoveByKey(key);                    tabControl.TabPages.RemoveByKey(key);                    tabControl.TabPages.RemoveByKey(key);                }            }            catch (Exception ex)            {                MessageBox.Show(ex.Message);            }        }    }

 

需要注意的，根据key移除tabPage的时候，如果有重名的tabPage的话。

删除规则，类似于队列，先添加到TabControl的，先被删除

如果找不到匹配的话，也不会报异常
