The use of accessor-modifiers is governed by the following restrictions:

  • An accessor-modifier may not be used in an interface or in an explicit interface member implementation.
  • For a property or indexer that has no override modifier, an accessor-modifier is permitted only if the property or indexer has both a get and set accessor, and then is permitted only on one of those accessors.
  • For a property or indexer that includes an override modifier, an accessor must match the accessor-modifier, if any, of the accessor being overridden.
  • The accessor-modifier must declare an accessibility that is strictly more restrictive than the declared accessibility of the property or indexer itself. To be precise:
  • If the property or indexer has a declared accessibility of public, any accessor-modifier may be used.
  • If the property or indexer has a declared accessibility of protected internal, the accessor-modifier may be either internal, protected, or private.
  • If the property or indexer has a declared accessibility of internal or protected, the accessor-modifier must be private.
  • If the property or indexer has a declared accessibility of private, no accessor-modifier may be used.

Example

Class A 
{ 
private string text = “init value”; 
public String Text 
{ 
       protected get{ return text;} 
       set{ text = value;} 
}
}
