Cast<TSource, TTarget>(TSource)
At post-compile time, casts an instance of a type into another. A post-compile time error is reported if the source type cannot be assigned to the target type.
Declaration
public static TTarget Cast<TSource, TTarget>(TSource o) where TSource : class where TTarget : classParameters
| Type | Name | Description |
|---|---|---|
| TSource | o | Instance to be casted. |
Returns
| Type | Description |
|---|---|
| TTarget | The object |
Type Parameters
| Name | Description |
|---|---|
| TSource | Source type. |

Remarks
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 TTarget is assignable from
TSource. If yes, the call to this method is
simply suppressed. If types are not assignable, a build error is issued.
