C#-C#翻页按钮的功能实现

Question

WindowsForm中添加一个TabControl控件，希望通过“上一页”和“下一页”按钮实现TabControl中各选项卡的切换。

Answer 1

TabControl中有个SelectedIndex属性可以设置或获取当前所选页的索引值

上一页:

var index = tabControl1.SelectedIndex;
tabControl1.SelectedIndex = --index < 0 ? 0 : index;

下一页:

var index = tabControl1.SelectedIndex;
tabControl1.SelectedIndex = ++index >= tabControl1.TabCount ?
tabControl1.TabCount - 1 : index;
