I. Complete definition and use of resources

<window x:class= "Demo008.mainwindow"        xmlns= "Http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x= "Http://schemas.microsoft.com/winfx/2006/xaml"        xmlns:sys= "clr-namespace:system;assembly= mscorlib "        title=" Resource "fontsize=" + loaded= "window_loaded" >    <!--complete notation--    < window.resources>        <ResourceDictionary>            <sys:string x:key= "str" > Sinking boat side thousand sails, the disease tree before the million wood spring. </sys:String>            <sys:double x:key= "dbl" >3.1415926</sys:Double>        </resourcedictionary >    </Window.Resources>    <StackPanel>        <textblock margin= "5" text= "{StaticResource RESOURCEKEY=STR} "/>    </StackPanel></Window>

ii. resource definition and use of shorthand

<window x:class= "Demo008.mainwindow"        xmlns= "Http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x= "Http://schemas.microsoft.com/winfx/2006/xaml"        xmlns:sys= "clr-namespace:system;assembly= mscorlib "        title=" Resource "fontsize=" + loaded= "window_loaded" >    <!-----    < window.resources>        <sys:string x:key= "str" > Sinking boat side thousand sails, the disease tree before the million wood spring. </sys:String>        <sys:double x:key= "dbl" >3.1415926</sys:Double>    </window.resources >    <StackPanel>        <textblock x:name= "TextBlock1" margin= "5" text= "{StaticResource str}"/>    </StackPanel></Window>

third, code lookup resources
The usual practice is as follows:

string text = this. FindResource ("str"). ToString (); Textblock1.text = Text;

If you know which object the resource is in, the resource dictionary can be accessed directly using the following method:

string text = this. resources["str"]. ToString (); Textblock1.text = Text;
