Context-Sensitive Keywords (C++/CLI and C++/CX)

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

• 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.

Examples

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);
}
