I have a newbie WPF question.

Imagine my user control has a namespace declaration like this:

xmlns:system="clr-namespace:System;assembly=mscorlib"

And I have resources for the user control like this:

<UserControl.Resources>
    <system:Int32 x:Key="Today">32</system:Int32>
</UserControl.Resources>

And then somewhere in my user control I have this:

<TextBlock Text="{StaticResource Today}"/>

This will cause an error because Today is defined as a integer resource, but the Text property is expecting a string. This example is contrived, but hopefully illustrates the question.

The question is, short of making my resource type exactly match the property type, is there a way for me to provide a converter for my resources? Something like IValueConverter for bindings or a type converter.

Thank you!

    It is possible if you use a Binding. It seems a little weird, but this will actually work:

    <TextBlock Text="{Binding Source={StaticResource Today}}" />

    It is because the Binding engine has built-in type conversion for the basic types. Also, by using the Binding, if a built-in converter doesn’t exist, you can specify your own.
