Examples
The following code example demonstrates the use of the SecurityCallContext class to interrogate the security context of calls to the methods of a ServicedComponent class.
// Accept a constructor string.

public ref class EmployeeInformation: public ServicedComponent
{
private:
// The employee's user name and salary.
String^ accountName;
double salary;
public:
// Get the employee's name. All users can call this method.
String^ GetName()
{
return (accountName);
}
// Set the employee's salary. Only managers can do this.
void SetSalary( double ammount )
{
if ( SecurityCallContext::CurrentCall->IsCallerInRole( "Manager" ) )
{
salary = ammount;
}
else
{
throw gcnew UnauthorizedAccessException;
}
}
// Get the employee's salary. Only the employee and managers can do this.
double GetSalary()
{
if ( SecurityCallContext::CurrentCall->DirectCaller->AccountName == accountName || SecurityCallContext::CurrentCall->IsCallerInRole( "Manager" ) )
{
return (salary);
}
else
{

}
}
