Context-Sensitive Keywords (C++ Component Extensions)

 

The latest version of this topic can be found at Context-Sensitive Keywords (C++ Component Extensions). Context-sensitive keywords are language elements that are recognized only in specific contexts. Outside the specific context, a context-sensitive keyword can be a user-defined symbol.

All Runtimes

Remarks

The following is a list of context-sensitive keywords:

• abstract

• delegate

• event

• finally

• for each, in

• initonly

• internal (see Member Visibility)

• literal

• override

• property

• sealed

• where (part of Generics)

For readability purposes, you may want to limit your use of context-sensitive keywords as user–defined symbols.

Example

The following code example shows that in the appropriate context, the property context-sensitive keyword can be used to define a property and a variable.

// context_sensitive_keywords.cpp  
// compile with: /clr  
public ref class C {  
   int MyInt;  
public:  
   C() : MyInt(99) {}  
  
   property int Property_Block {   // context-sensitive keyword  
      int get() { return MyInt; }  
   }  
};  
  
int main() {  
   int property = 0;               // variable name  
   C ^ MyC = gcnew C();  
   property = MyC->Property_Block;  
   System::Console::WriteLine(++property);  
}
