API vs WebService - Confusion on usage - Real world example required


API vs WebService - Confusion on usage - Real world example required

I wish this help you Ok, in regards to your question, a Web Service is a type of API, but it is Web Based. Developers can hook up code to this, which can communicate back with their own code, to do something. An example of this would be the Oxford Dictionary API, in which you can send it a word, and it will reply with their meanings.
An API on the other hand, doesn't have to be web based, so for example, OpenGL, or SpriteKit are examples of non-web based APIs which you can supply with data for it to manipulate and output.

around this issue Assuming you're not talking about events - of course you can program around it. The point is to make it nicer and cleaner.
code :
protected void Sort()
{
    foreach (string key in _dBase.Keys)
    {
      Array.Sort<Pair<string, Dictionary<string, T>>>(_dBase[key], 
            new Comparison<Pair<string, Dictionary<string, T>>>(
        delegate(Pair<string, Dictionary<string, T>> a, Pair<string, Dictionary<string, T>> b)
        {
            if (a == null && b != null)
                return 1;
            else if (a != null && b == null)
                return -1;
            else if (a == null && b == null)
                return 0;
            else
                return a.First.CompareTo(b.First);
        }));
    }
}
Array.Sort<Pair<string, Dictionary<string, T>>>(_dBase[key], 
   new Comparison<Pair<string, Dictionary<string, T>>>(
   delegate(Pair<string, Dictionary<string, T>> a, Pair<string, Dictionary<string, T>> b)
   {
Array.Sort<Pair<string, Dictionary<string, T>>>(_dBase[key], (a,b) =>
   {

it helps some times Browsable means that a designer, like Visual Studio's WPF designer named Cider, shows the property in the designer. Since attached properties are not an actual property of a type and can be applied to almost type it is hard for the designer to know when to show or not show the property. These attributes are a way for a developer to let the designer know a certain attached property should be shown in the designer. In other words: Browsable. This specific attribute lets the designer know that this attached property should be browsable on types that have the specified attribute applied to them.
The attached property:
code :
public class WhenAttributePresentTestControl : Grid
{
    public static readonly DependencyProperty ShowWhenCustomAttributePresentProperty = DependencyProperty.RegisterAttached(
      "ShowWhenCustomAttributePresent",
      typeof(int),
      typeof(WhenAttributePresentTestControl));

    public static void SetShowWhenCustomAttributePresent(UIElement element, int value)
    {
        element.SetValue(ShowWhenCustomAttributePresentProperty, value);
    }

    [AttachedPropertyBrowsableWhenAttributePresentAttribute(typeof(MyCustomAttribute))]
    public static int GetShowWhenCustomAttributePresent(UIElement element)
    {
        return (int)element.GetValue(ShowWhenCustomAttributePresentProperty);
    }
}
[MyCustomAttribute]
public class CustomLabel : Label
{
}

public class CustomLabelNoCustomAttribute : Label
{
}

this one helps. The concept is used a lot, especially for date/time. You also have it in non-metric units of measurement, miles-yards-feet-inches, pounds-ounces, etc.

hop of those help? It is a fundamental "atom" in the composition of observable event streams and comes up in a variety of situations - but one of the most common uses for Observable.Never in practice is in writing tests. It easily enables robust checking of timeout logic, for example - and is often combined with the TestScheduler or other virtual time schedulers in test scenarios. If you examine the source code of Rx itself, you find it appears in many unit tests.
