            <!--SIP 包含数字和小数点，按住句号键可以显示“.,-”-->
            <TextBox InputScope="Number" />

            <!--SIP 按“123”键切换到电话号码键盘，按住句号键可以显示“.,-”-->
            <TextBox InputScope="NameOrPhoneNumber" />

            <!--SIP 默认显示数字和符号键盘-->
            <TextBox InputScope="CurrencyChinese" />

                    </InputScope>
                </TextBox.InputScope>
            </TextBox>

            <!--后台将此 TextBox 的 InputScope 设置为“EmailUserName”-->
            <!--SIP 包括 @ 和 .com 键，按住 .com 键可以显示“.org .com .edu .net”-->
