UWP 圓角TextBox和PassWord框

最近在作一個UWP項目,登陸的用戶和密碼框須要圓角的,因爲UWP的TextBlock 和PasswordBox是沒有CornerRadius屬性的,因而我就使用了一個Border嵌套在最外層,設置其餘CornerRadius="20"

實現代碼以下:

                       <!--帳號-->
                        <Border Background="#FFFFFF" CornerRadius="20">
                            <RelativePanel Margin="10,0,0,0" Padding="5">
                                <TextBlock  x:Name="tbNumber" Text="帳號：" RelativePanel.AlignVerticalCenterWithPanel="True" />
                                <TextBox x:Name="txtUserName" FontSize="16"  RelativePanel.RightOf="tbNumber" PlaceholderText="請輸入GW號/手機號"
                                         RelativePanel.AlignRightWithPanel="True" 
                                         RelativePanel.AlignHorizontalCenterWithPanel="True"
                                         RelativePanel.AlignVerticalCenterWithPanel="True"
                                         Margin="0,5,0,0" 
                                         BorderThickness="0"
                                         InputScope="NameOrPhoneNumber"/>
                            </RelativePanel>
                        </Border>
                        <!--密碼-->
                        <Border Background="#FFFFFF" CornerRadius="20" Margin="0,20,0,0">
                            <RelativePanel Margin="10,0,0,0" Padding="5">
                                <TextBlock  x:Name="tbPwd" Text="密碼：" RelativePanel.AlignVerticalCenterWithPanel="True" />
                                <PasswordBox x:Name="txtPwd" RelativePanel.RightOf="tbPwd" PlaceholderText="請輸入密碼"
                                             RelativePanel.AlignRightWithPanel="True" IsEnabled="True"
                                             BorderThickness="0" 
                                             RelativePanel.AlignHorizontalCenterWithPanel="True"
                                             RelativePanel.AlignVerticalCenterWithPanel="True"
                                             Margin="0,5,0,0"/>
                            </RelativePanel>
                        </Border>
