为什么StringBuilder被删除？(Why StringBuilder was removed?)

 我的问题很简单。 前段时间StringBuilder被删除了。 这可能是什么原因？ 我现在怎么处理大字符串？ 

My question is simple. Some time ago StringBuilder was removed. What may be the reason of that? How can I deal with large strings now?

 尝试  
<ul class="span3 navigation">
    <li>
        <a href="#location">Location</a>
        <ul class="nav">
            <li><a href="#region">Region</a></li>
            <li><a href="#country">Country</a></li>
            <li><a href="#state">State</a></li>
        </ul>
    </li>
    <li>
        <a href="#device">Device</a>
        <ul class="nav">
            <li><a href="#gateway-unit">Gateway Unit</a></li>
            <li><a href="#modbus-unit">Modbus Unit</a></li>
            <li><a href="#meter-unit">Meter Unit</a></li>
        </ul>
    </li>
    <li><a href="#user">Software User</a></li>
    <li><a href="#global-parameters">Global Parameters</a></li>
</ul>
 
 然后  
jQuery(function ($) {
    var $uls = $('.navigation ul').hide();
    $('.navigation li:has(ul) > a').click(function(){
        var $ul = $(this).next('ul').show();
        $uls.not($ul).hide();
    })
});

then 
jQuery(function ($) {
    var $uls = $('.navigation ul').hide();
    $('.navigation li:has(ul) > a').click(function(){
        var $ul = $(this).next('ul').show();
        $uls.not($ul).hide();
    })
});
