推荐答案

在<$中设置每个RadioButton的Check状态c $ c> Form_Load event

rbOne.Checked = False

或

rbOne.CheckState = CheckState.Unchecked

。



虽然我没有遇到这种情况，但是有一个IDE可能会自动假设至少有一个RadioButtons应该被检查，因为它们都被组合在一个控件中，在这种情况下是一个GroupBox。



Tab Index仅控制Tab序列 - 按下TAB键时光标从一个控件跳到下一个控件的顺序。但是我不确定它是否会确定是否应该检查RadioButton。

.

Although I haven't been in this situation, there is a possibility that the IDE will automatically assume that at least one of the RadioButtons should be Checked since they are all grouped together in a single control, in this case a GroupBox.

The "Tab Index" controls only the Tab sequence - the order in which the cursor will jump from one control to the next when the TAB key is pressed. However I am not sure if it will determine if a RadioButton should be checked or not.

只关注你的问题..只需打开这个radiobuttons所在的窗口。选择每个radiobuttons并将checked属性更改为false。

to be only concern to your problem..just open that window where this radiobuttons are. select every radiobuttons and change checked property to false.

在这种情况下，您必须手动将所有RadioButton对象设置为

RadioButton Form_Shown 事件中.Checked = False 。

Hi, in this case you have to manually set all RadioButton objects to
RadioButton.Checked = False in the Form_Shown event.
