]ObjectExt::Coalesce(T0, T1) method
Implementation of ‘??’ operator translation for non-nullable types.
template<typename T0,typename T1> static auto System::ObjectExt::Coalesce(T0 value, T1 func)
| Parameter | Description |
|---|---|
| T0 | LHS value type. |
| T1 | Type of lambda encapsulating RHS expression. |
| Parameter | Type | Description |
|---|---|---|
| value | T0 | LHS value. |
| func | T1 | RHS expression. |
ReturnValue
If LHS value is not null, returns LHS, otherwise calculates RHS expression and returns result.
