对弱英语的评论。我在很多天里搜索goolge但我没有找到解决方案。我的问题如下。

当我从工具箱中绘制按钮到winform时，它的默认颜色就像灰色，悬停颜色就像橙色。

推荐答案

这是一个自定义按钮的例子：

Here is an example for customizing a Button :

Public Class customButtom
    Inherits Button

    Public Sub New()
        MyBase.BackColor = my_BackColor
    End Sub

    Shadows Property BackColor As Color
        Get
            Return my_BackColor
        End Get
        Set(value As Color)
            my_BackColor = value
            MyBase.BackColor = value
            Me.Invalidate()
        End Set
    End Property

    Private my_BackColor As Color = Color.Blue ' <- this is your Default-Value

    Property HoverBackColor As Color
        Get
            Return my_HoverBackColor
        End Get
        Set(value As Color)
            my_HoverBackColor = value
        End Set
    End Property

    Private my_HoverBackColor As Color = Color.Green ' <- this is your Default-Value




    Private Sub Button_MouseEnter(sender As Object, e As System.EventArgs) Handles Me.MouseEnter
        MyBase.BackColor = my_HoverBackColor
    End Sub

    Private Sub Button_MouseLeave(sender As Object, e As System.EventArgs) Handles Me.MouseLeave
        MyBase.BackColor = my_BackColor
    End Sub

End Class

默认背景颜色由控制面板控制，适用于所有应用程序。我认为你不想改变这个设置。因此，更改的范围应该在您的应用程序内。这意味着您需要通过代码控制背景颜色。



如果要更改表单内的控件，可以使用递归循环的方法表单中的所有控件。



该方法可能类似于

Default background color is controlled by the Control Panel and applies to all applications. I take it you don't want to change this setting. So the scope of the change should probably be inside your app. This means that you'd need to control the background color via code.

If you want to change the controls inside a form you can use a method which loops recursively through all the controls inside a form.

The method could look something like

/// <summary>
/// Changes recursively the color of all buttons inside provided control
/// </summary>
/// <param name="parentControl">Control whose controls to investigate</param>
public void ChangeBackgroundColor(System.Windows.Forms.Control parentControl) {
   // Loop through each control inside the given parent
   foreach (System.Windows.Forms.Control control in parentControl.Controls) {
      // Recursively update the color of the controls inside this control
      ChangeBackgroundColor(control);
      // If the contol is a button change the background color
      if (control.GetType() == typeof(System.Windows.Forms.Button)) {
         control.BackColor = System.Drawing.Color.Red;
      }
   }
}

调用方法如

And calling the method like

ChangeBackgroundColor(this);

希望这会有所帮助。



附加：



VB版可能看起来像

Hope this helps.

ADDITION:

VB version could look like

Private Sub ChangeBackgroundColor(ByRef parentControl As System.Windows.Forms.Control)
   ' Loop through each control inside the given parent
   For Each control As System.Windows.Forms.Control In parentControl.Controls
      ' Recursively update the color of the controls inside this control
      ChangeBackgroundColor(control)
      ' If the contol is a button change the background color
      If (TypeOf control Is System.Windows.Forms.Button) Then
         control.BackColor = System.Drawing.Color.Red
      End If
   Next
End Sub

和电话

and the call

ChangeBackgroundColor(Me)
