NOTE: see Cheetah's answer below as it identifies a prerequisite to get this solution to work. Setting the BackColor of the TextBox.

我认为您真正想要做的是启用 TextBox 并将 ReadOnly 属性设置为 true.

I think what you really want to do is enable the TextBox and set the ReadOnly property to true.

在禁用的 TextBox 中更改文本颜色有点棘手.我认为您可能需要子类化并覆盖 OnPaint 事件.

It's a bit tricky to change the color of the text in a disabled TextBox. I think you'd probably have to subclass and override the OnPaint event.

ReadOnly 虽然应该给你与 !Enabled 相同的结果，并允许你保持对 TextBox 的颜色和格式的控制.我认为它仍然支持从 TextBox 选择和复制文本，这在禁用 TextBox 的情况下是不可能的.

ReadOnly though should give you the same result as !Enabled and allow you to maintain control of the color and formatting of the TextBox. I think it will also still support selecting and copying text from the TextBox which is not possible with a disabled TextBox.

另一种简单的替代方法是使用 Label 而不是 TextBox.

Another simple alternative is to use a Label instead of a TextBox.
