System::AsCast method
System::AsCast(const Source&) method
Casts the source type to the result type using ‘as’ operator cast. Used when simple constructor-like cast is needed.

| Parameter | Description |
|---|---|
| Source | The source type. |
| Result | The result type. |
| Parameter | Type | Description |
|---|---|---|
| value | const Source& | Object to cast. |
ReturnValue
