推荐答案

您可以改用System.Windows.Forms.TrackBar.

同样，这样的控件也太容易实现了.真的没有什么要讨论的，只是从System.Windows.Forms.Control派生的.

正如您没有告诉slider的声明(可能有些胡言乱语)一样，我不知道为什么它不能编译.就像Controls属性的名称所建议的那样，它应该是Control(难读的帮助信息吗?).我也不相信这是真正的错误信息，因为语法看起来很混乱.如果您需要帮助，请务必准确.

瞧，即使名字"System.Windows.Forms.Cntrols"也是用不正确的拼写写的；复制和粘贴太难了吗?表现出这种态度时，谁会乐意回答?

You can use System.Windows.Forms.TrackBar instead.

Also, controls like that are too easy to implement; there is nothing to discuss here, really, just derive from System.Windows.Forms.Control.

As you did not tell the declaration of slider (probably, some gibberish), I don''t know why it does not compile; it should be Control, as the name of the Controls property suggests (is is that hard to read help?). I also don''t believe this is real error message, as grammar looks broken. If you need some help, please be precise.

Look, even the name "System.Windows.Forms.Cntrols" is written in incorrect spelling; is it too hard to copy and paste? Who will be happy to answer when such attitude is manifested?
