| microsoft.public.dotnet.languages.csharp |

The thread variable "oThread" is also a private class variable. Let's say the loop has executed one pass and xxx is equal to a new instance of clsXXX and oThread is ... |

| new public void draw() versus public void override draw() (2 replies) |

The two ways I'm referring to are using the "new" keyword and the "override" modifier when declaring a method. When is one preferred over the other, or is the "new" modifier just there to accommodate bad design in the first place (say someone forgot to declare a virtual method in their base cl... |

Reflecting the private members of the class reveals that there is also a corresponding private field (of type object) named EventA. From the FieldInfo, I can find no way to discern that the field is associated with the event. A workaround of course is to go through the reflected events and... |

| 'finally' usage? (2 replies) |
| microsoft.public.dotnet.languages.csharp |
| In some place Microsoft gives the advise to use 'finally' to ensure some task is done. For example, to be sure a connection will be closed: try { SqlConnection con new SqlConnection(); ... do something } // Position 1 catch { ... do something } // Position 2 finally { con.Close(); } that's because the code inside of 'finally' is always executed. (If no exception is raised, after 'Position 1', othe... |

| WishList: Readonly Arrays (3 replies) |

Thus any changes to X would be reflected in it. However, anyone given R would be prevented from making changes to the array. Also, the type used for R would inherit from Integer() so that you can pass it to methods that ne... |
