public static TargetType Cast<SourceType, TargetType>( SourceType o ) where SourceType : class where TargetType : class
Instance to be casted.
- Source type.
- Target type.
The object o casted as TargetType.
The purpose of this method is to make a source code compilable even when an interface will be implemented at post-compile time. PostSharp ensures that TargetType is assignable from SourceType. If yes, the call to this method is simply suppressed. If types are not assignable, a build error is issued.
