My Magic Eight Ball says you want to Split some comma-separated values within a String. Have you searched CP for articles related to this task?

Wow - that actually worked, sort of. But it gave an STL sample as first hit. Perhaps you should have put C# in there and used site: to search CP ?

I remember there used to be a hidden Eight Ball in MS Access, good times. There was something hidden in most of the MS Office type applications back then; Excel had a little 3D world that you could fly around in!

Problem serializing object to XML

Hi
I have problem returning an XML document in my c# code. The code I am using is as follows:

string xmlString = null;
MemoryStream memoryStream = new MemoryStream();
XmlSerializer xs = new XmlSerializer(typeof(T));
XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8);
xs.Serialize(xmlTextWriter, obj);
memoryStream = (MemoryStream)xmlTextWriter.BaseStream;
xmlString = UTF8ByteArrayToString(memoryStream.ToArray());
return xmlString;

private static string UTF8ByteArrayToString(byte[] characters)
{
UTF8Encoding encoding = new UTF8Encoding();
string constructedString = encoding.GetString(characters);
return (constructedString);
}

The problem I have is when the xml string is returned, the namespace and declaration at the start of the xml string is not in a well formed xml document.

What it is doing is inserting / in front of the equal sign in the name space, thus:

Therefore, I am looking for advice on how to stop this happening.

Can anyone help?

Thanks

Your example xml header is not showing up. Maybe you need to enclose it in code tags or pre tags.

Usually you don't copy VB.NET code into C#.

Need custom software developed? I do custom programming based primarily on MS tools with an emphasis on C# development and consulting.

Thanks for the reply, however it wasn't very helpful.

My task is to convert a program that I wrote from VB to C#. I am not copying the VB directly in. I am trying to re-write the program in C#. As a complete novice, all I can do is try. Are you saying that all of my code is completely wrong?

Try changing the above to

public char DIAMONDS

This looks OK, are you sure the quote characters are definitely single quotes? If you use double quotes then the compiler thinks it's a string rather than a single character.

That's not really the "right" error you know, it should say "Syntax error: this is C#, not VB"

Blind suggestion (untested)

namespace VDP
{
   public class GlobalVar
   {
      public const string DIAMONDS = "♦";
   }
}

namespace VDP
{
   public partial class frmMain : Form
   {
      //snippet
      switch (x)
      {
         case globalVar.DIAMONDS:
            break;
      }
   }
}

Hint: the right side of a case should be an actual constant, not a "thing that is logically constant", but syntactically constant.

Good luck

Thanks, like I said, I am just a novice this is my first project to convert the Poker game I wrote in lesson 1 to C#.

I get the following error after following your suggestions:

I tried using "♦"; in lieu of "♦"; It did not create the diamond symbol. Do I need to do something else? I had wanted to use code versus symbols on my original VB code but was unable to get it to work.

   public class Example

               bool i;
               switch (x)

                     case Global.strOperator:
                           {
                                 i = true;

Hi,

look at the line numbers, the error message points here: case globalVar.DIAMONDS:
and of course it is right, you made _DIAMONDS a const, however DIAMONDS isn't const, it is a property.

the solution is easy: make your _DIAMONDS a public const and get rid of the property and the underscore.

ok I changed it to

public const string DIAMONDS = "♦";

I have two lines of code thus far that utilize DIAMONDS

1: TempDeck[x] = TemDeck[x] + of + globalVar.DIAMONDS
2: Case globalVar.DIAMONDS

The first line of code was previoulsy working (or at least not erroring out). Now all references return the following error:

Member VDP.GlobalVar.DIAMONDS cannot be accessed with an instance referance; qualify it with a type instead. I had originally started out with public const string DIAMONDS but switched it after having other problems
