我已经使用Visual Studio为Windows窗体应用程序中的应用程序设置生成一个类.调试时,应用程序设置不会填充值.为什么没有价值观?
这是生成的代码:

我需要创建一个新的预留并插入它.但是,在构建预留插入时,我没有服务实体,但我确实有服务的Id值.有没有办法在不先获取服务的情况下插入我的预订?
这主要是出于教育目的.我正在尝试创建在此示例中使用的InputMapper类:
var mapper = new InputMapper<SomeType>();
mapper.Map("some user input", someType => someType.IntProperty, "Input was not an integer");
mapper.Map("some user input", someType => someType.BoolProperty, "Input was not a bool");
SomeType someTypeInstance = mapper.CreateInstance();

我的InputMapper类包含使用Map()方法创建的所有映射的集合.CreateInstance()将遍历映射,尝试转换用户输入并将其分配给lambda表达式中使用的属性.当它循环时,它将保存抛出的任何FormatExceptions的集合.
我的问题是:
谢谢!
斯凯特博士要求提供有关我的意图的更多信息.
InputMapper类将用于将用户输入分配给任何对象的成员,负责将用户输入转换为属性类型.可以从上面的示例推断出类的接口.

我可以在Visual Studio 2010中折叠foreach,using和其他c#代码块,就像我可以折叠方法,属性,类,命名空间等一样吗?有时它会非常有用.

我有两个类:Form和Field.
Form有一个名为Fields的属性,它是Field对象的List.
表单有一个名为Prefix的属性.
Field有一个方法需要使用包含它的Form的Prefix属性.
这是我现在正在做的事情:
class Form
{
private List<Field> fields;
public string Prefix { get; set; }
public void AddField(Field field)
{
field.Form = this;
fields.Add(field);
}
}
class Field
{
public void RenderHtml()
{
// render html element with ID attribute
// prefixed with the parent form's Prefix property
}

是否有任何工具将SQL Server元数据的检索封装到一个漂亮的对象模型中?
我的当前需求是从SQL Server 2000-2008 R2收集这些东西:
所以,也许给定一个SqlConnection对象,我可以这样做:
var dbs = conn.GetDatabases();
var db = dbs.Single(x => x.Name == "AdventureWorks");
var tables = db.GetTables();
var triggers = db.GetAllTriggers();

当然,这些例子会非常方便,但任何类型的对象模型都会比我现在所做的更好.在我建立自己之前,那里有什么东西吗?
