Use
用
tabControl1.SelectedIndex;
This will give you selected tab index which will start from 0 and go till 1 less then the total count of your tabs
这将为您提供选定的标签索引，该索引将从 0 开始，直到标签总数减少 1
Use it like this
像这样使用它
private void tabControl1_SelectedIndexChanged(object sender, EventArgs e)
{
switch(tabControl1.SelectedIndex)
{
case 0:
{ some code here }
break;
case 1:
{ some code here }
break;
}
}

Simply use tabControl1.SelectedIndex:
只需使用tabControl1.SelectedIndex：
if (tabControl1.SelectedIndex == 0)
{ some code here }
if (tabControl1.SelectedIndex == 1)
{ some code here }

This is a much better approach.
这是一个更好的方法。
private int CurrentTabPage { get; set; }
private void tabControl1_SelectedIndexChanged(object sender, EventArgs e)
{
CurrentTabPage = tabControl1.SelectedIndex;
}
In this way every time the tabindex is changed, our required CurrentTabPage would automatically updated.
这样每次更改 tabindex 时，我们所需的 CurrentTabPage 都会自动更新。
