I guess you could use the Encoding class (System.Text).

Encoding encoding = Encoding.UTF8;
byte[] b = encoding.GetBytes(s);

But you have to use the right encoding.

Hope this helps.

For Conversion of String to Byte Array go like this,

public static byte[] StrToByteArray(string str)
{
System.Text.ASCIIEncoding encoding=new System.Text.ASCIIEncoding();
return encoding.GetBytes(str);
}

Don't go with Base 64 because it is of invalid length.

Or simply:

byte[] data = System.Text.Encoding.ASCII.GetBytes(str);

do a string.Split and pass that Ctrl char (the square i see) ~~and~~ as the delimiter.

xacc.ide-0.2.0.57 - now with C# 2.0 parser and seamless VS2005 solution support!

Here you go :

String fixString = "Whateever";<br />
string[] fixArray = fixString.Split(Convert.ToChar(1)); <br />
//I used 1 because FIX message uses this as delimiter...<br />
HashTable fixTable = new HashTable();<br />
string[] fieldArray = null;<br />
for (int fieldCount = 1; fieldCount < message.Length; fieldCount++)<br />
{<br />
fieldArray = fixArray[fieldCount].Split('=');<br />
fixTable.Add(fieldArray[0].ToString(), fieldArray[1].ToString()); <br />
}

Hope this helps.
by the way, I too used all this in my early carrier. Wink | ;)

if i am able to do it like this
100=ARCA10=169|0|
using substring
now i have to get value of first tag
eg
100=
Result should be "ARCA"
i want it in seperate string

String fixString = "Whateever";<br />
string[] fixArray = fixString.Split(Convert.ToChar(1)); <br />
//I used 1 because FIX message uses this as delimiter...<br />
HashTable fixTable = new HashTable();<br />
string[] fieldArray = null;<br />
for (int fieldCount = 1; fieldCount < message.Length; fieldCount++)<br />
{<br />
fieldArray = fixArray[fieldCount].Split('=');<br />
fixTable.Add(fieldArray[0].ToString(), fieldArray[1].ToString()); <br />
}<br />
string firstTagString = fixTable["100"].ToString()

This will give you string which is there in tag 100, no matter at what position it is at.
I am telling you this because FIX is a tag based protocol and not a position based. The position may vary from message to message.
It is a more generalized solution for your scenario.
Success

you do message.Length

you mean fixString.Length here
Am i right
even than its crashing for my message

My Mistake OMG | :OMG:

It should be fixArray
Here's your code

String fixString = "Whateever";<br />
string[] fixArray = fixString.Split(Convert.ToChar(1)); <br />
//I used 1 because FIX message uses this as delimiter...<br />
HashTable fixTable = new HashTable();<br />
string[] fieldArray = null;<br />
for (int fieldCount = 1; fieldCount < fixArray.Length; fieldCount++)<br />
{<br />
fieldArray = fixArray[fieldCount].Split('=');<br />
fixTable.Add(fieldArray[0].ToString(), fieldArray[1].ToString()); <br />
}<br />
string firstTagString = fixTable["100"].ToString()

Ankit Aneja8-Jun-07 2:33

its still giving index was outside the bounds of array

after this line
string firstTagString = fixTable["100"].ToString();
it jumps out and go to lines after
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}

Dude,
I ran it with the same code...
If it is running for exception than it means ur message did not contain message with tag 100...
nyway, for which company do you work?
