C#：透明按鈕

 

設置btn FlatStyle為: Flat

設置btn背景為：Transparent

 

 

 

 

 

 

 

 

更徹底的話就要使用如下方法————

/// <summary>

/// 設置透明按鈕樣式

/// </summary>

private void SetBtnStyle(Button btn)　　//在Form1_Load時候調用
{

    btn.FlatStyle = FlatStyle.Flat;//樣式

    btn.ForeColor = Color.Transparent;//前景

    btn.BackColor = Color.Transparent;//去背景

    btn.FlatAppearance.BorderSize = 0;//去邊線

    btn.FlatAppearance.MouseOverBackColor = Color.Transparent;//鼠標經過

    btn.FlatAppearance.MouseDownBackColor = Color.Transparent;//鼠標按下

}

private void btn_MouseHover(object sender, EventArgs e)　　//分別設置進你要令其透明控件的動作

{

    Button btn = sender as Button;

    btn.FlatAppearance.BorderSize = 1;

}



private void btn_MouseLeave(object sender, EventArgs e)　　//分別設置進你要令其透明控件的動作

{ 

　　Button btn = sender as Button; btn.FlatAppearance.BorderSize = 0;
}
