• lkld999 .Item property doesn't exist for ArrayLists???

  I'm getting compiler errors when trying to reference the .Item property for ArrayLists in my code. All the documentation I can find says this property does exist. But C# is telling me otherwise. If I say: ArrayList MyList = new ArrayList(); Object o = MyList.Item[3]; I get the compile-time error: System.Collections.ArrayList does not contain a definition for "Item" And as I'm entering my code and type "Mylist.", the IDE's auto-complete popup suggests "IsSynchronized" or "LastIndexOf" as the members at the place I'd expect to see the .Item property. I'm a bit of a C# newbie. Thanks for any help... It is true that the ArrayList class has an ...Show All

• mastermind1429 Stripping diacriticals from string?

  Is there a .Net string method that will strip diacriticals from strings That is, what can I replace ToNoDiacriticals with to get the following to work: string foreign = "Bia owie a"; if (foreign.ToNoDiacriticals().Equals("Bialowieza"))     System.Console.Writeln("Works!"); You can use Path.GetInvalidFileNameChars and Path.GetInvalidPathChars to test for the non-diacritical characters you want to remove... System.IO.Path.InvalidPathChars may help. Good luck. I made a typo; the comparison should be if ((c < 0x0300) || (c > 0x03FF)). Are you sure you're using NormalizationForm.FormKD The others will convert accented letters to their canonical form, which is not what I wan ...Show All

• McGeeky AHHH serial port class

  OK, I have some basic code to send some commands and get some responses back from a serial device. One function calls SerialPort.Write(byte[], int, int), then I call SerialPort.ReadLine() after. This timeout on my serial port is 4 seconds. The data comes base in far less than a second. This process seems to work for about 7 send and receive calls and then starts timing out as if when I send commands after that, it doesn't get anything back, BUT it does. I know it keeps getting stuff back because if i close my app and run hyperterm when I connect to the serial port hyperterm flushes the input buffer and I get everything the .net 2.0 SerialPort class said wasn't there. can someone tell me what exactly I am doing wrong Does the serial ...Show All

• zoezoo [Best Practice] Verify a value is part of an enumeration

  What would be the best way for verifying, upon converting an int to an enumerated type, that the value actually exists in the enumeration Ideally, this would work with [Flags] and non-[Flags] enumerated types. A case statement would work, but is clearly undesirable, unless one does some sort of code generation. Perhaps checking int.TryParse((EnumeratedType){int value}, out dummy).ToString()) would work, but that seems awfully kludgy. Luke, I've provided a few techniques for validating enums on InvalidEnumArgumentException topic on the new MSDN Wiki. Regards David Thanks for the post David there's good useful stuff there. Now the whines First I understand stuff happens but it is a rea ...Show All
