c# - 帮助覆盖 C# .NET

Question

我需要覆盖 Tabcontrol GetTabRect。

  protected override Rectangle GetTabRect(int index)
    {...}

我收到这个错误

Error 1 'TabControl.GetTabRect(int)': cannot change access modifiers when overriding 'public' inherited member 'System.Windows.Forms.TabControl.GetTabRect(int)'

Error2'TabControl.GetTabRect(int)': cannot override inherited member 'System.Windows.Forms.TabControl.GetTabRect(int)' because it is not marked virtual, abstract, or override

我该怎么做？

编辑

如果我使用公共(public):

TabControl.GetTabRect(int)': cannot override inherited member 'System.Windows.Forms.TabControl.GetTabRect(int)' because it is not marked virtual, abstract, or override

Answer 1

该方法是公开的。所以当你覆盖它时，你不能让它受到保护。因此，您必须保持公众可见性。

它应该是这样的:

public override Rectangle GetTabRect(int index)
