示例

下面的代码示例演示如何使用此方法来确定方法的 ServicedComponent 调用方是否为指定角色。

// 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;
   }
}

// Set the employee's salary. Only managers can do this.
public void SetSalary (double ammount)
{
    if (SecurityCallContext.CurrentCall.IsCallerInRole("Manager"))
    {
        salary = ammount;
    }
    else
    {
        throw new UnauthorizedAccessException();
    }
}

' Set the employee's salary. Only managers can do this.
Public Sub SetSalary(ByVal ammount As Double) 
    If SecurityCallContext.CurrentCall.IsCallerInRole("Manager") Then
        salary = ammount
    Else
        Throw New UnauthorizedAccessException()
    End If

End Sub
