'is' 'as'
Function If the run-time type of an expression result is compatible with a given type, the 'is' operator is checked by it. 'as' operator is used to perform conversion between compatible reference types or Nullable types.
Type Boolean Non-Boolean
Return type when conversion happens successfully If the given object is of the same type, then 'is' sends true 'as' sends object when the type of object is compatible with the given type
Return type when conversion not possible If the given object is not of the same type, then 'is' sends false 'as' returns null if conversion not possible
Use Case 'is' is used for Only Boxing Unboxing and reference conversions 'as' operator is used only for nullable, reference and boxing conversions
