如何使用Javascript拆分?
当我们在登台服务器上导航到WCF服务时,我们得到一个"当前配置系统不支持用户范围设置"编译异常.
我们通过使用WCF服务的应用程序以及直接导航到.svc测试页面时获得此异常.
这在我们的测试服务器上运行良好 - 并且网站以相同的方式设置(在IIS,文件系统等中).
有人知道这会是什么吗?
我正在制作一个符合Web UI 508的要求,其中一个要求是"禁用CSS时使用Web UI".我们有几个地方使用style=display:inline和显示/隐藏元素,style=display:none并使用JS函数调用相应地调用它们.当我禁用CSS(使用WAT2.0)时,隐藏的元素也会显示,这不会使用户界面很好.我们在几个地方都有这些东西,比如折叠/扩展描述,鼠标移动弹出等等,
除了使用样式标签之外,还有其他方式来显示/隐藏元素吗?请指教!

blablablamorecontentblablabla?name=michel&score=5&age=28&iliedabouttheage=true

看起来像常规查询字符串是,但我不在任何Web上下文中
现在我想通过他们的键提取值(在=符号之后),例如,名称(michel),分数(5),年龄(28)等.
通常我解析字符串就像获取单词'name'的字符串中的位置,然后将5添加到它(长度'name =')并将此位置命名为'start'然后搜索&-sign并命名该位置'结束',然后在位置开始和结束之间获取字符串.
但必须有一个更好的解决方案,这是一个正则表达式的事情吗?
And I mean this in the easiest way. Say you have a function with the following signature:
public static Expression<Func<T, bool>> CreateExpression<T>(string value)
{
// ...
}

Usually it will create a more complex expression of some sort, but if the value is null the method should return a constant, always true expression. In other words:
public static Expression<Func<T, bool>> CreateExpression<T>(string value)
{
if(value == null)
return x => true;
// ...
}

How do I import this file into SQLite so that these are created automatically?
After using the OpenFileDialog for selecting a file the Environment.CurrentDirectory changes to the folder of the file. Is this normal?
From my understanding Environment.CurrentDirectory should always be the application folder.
