Returns a value that indicates whether the installed Silverlight plug-in supports the specified version.
Assembly: System.Windows (in System.Windows.dll)
- Type: System.String
The version to check, in the form of major.minor.build.revision See Remarks for more information about the string form.
Return ValueType: System.Boolean
true if the version can be supported by the installation; otherwise, false.
The version string contains one through four integer values that are separated by dots, for example, "2.0.30908.0". The sequence of integers represents the major, minor, build, and revision numbers. For more information about versioning, see Silverlight Plug-in Versioning.
The following code example demonstrates how to use this method.
// The Host object, which represents the host Silverlight plug-in. System.Windows.Interop.SilverlightHost host = Application.Current.Host; // The following code demonstrates how to use the Host object // to access other APIs in the System.Windows.Interop namespace. // The IsVersionSupported method. This method is useful when // you want to implement an upgrade experience in managed code. bool isSupported = host.IsVersionSupported("2.0.30908.0"); // Read-only properties of the Host object. System.Windows.Media.Color pluginBackground = host.Background; bool loaded = host.IsLoaded; Uri source = host.Source; // The Settings object, which represents Web browser settings. System.Windows.Interop.Settings settings = host.Settings; // Read/write properties of the Settings object. settings.EnableFrameRateCounter = true; settings.EnableRedrawRegions = true; settings.MaxFrameRate = 60; // Read-only properties of the Settings object. bool windowless = settings.Windowless; bool htmlAccessEnabled = settings.EnableHTMLAccess; // The Content object, which represents the plug-in display area. System.Windows.Interop.Content content = host.Content; // The read/write IsFullScreen property of the Content object. // See also the Content.FullScreenChanged event. bool isFullScreen = content.IsFullScreen; // Read-only properties of the Content object. These properties do // not contain meaningful values until after the Content.Resized // event occurs for the first time. double actualWidth = content.ActualWidth; double actualHeight = content.ActualHeight;
