dividing stringbuilder and appending together

[trixxy]

How do i divide the length of the string by 4?

and then find how many characters each string builder should handle.

and after that append all the results together.

Can you be a bit more specific? Give us an example of what you mean...

This should get you started. From here you will have to flush out for things like your original string not being an even multiple of 4, and whatever you mean by appending the results together. To me, appending the results of dividing a string would result in your original string and I doubt that's what you mean, but I can't read in a different goal.


{

string szSample = "This is some text";
int nSample = szSample.Length;// Should yield 17
int nQuarter = nSample/4; 
}

as i'll be working with very long strings, my program can't process so much characters. so i need to divide the string into segments to decode the different segments. then after that combine all the segments together. i'm working with a hex to ascii converter btw.

private string HexString2Ascii(string HexString)
{
StringBuilder Sb = new StringBuilder();
for (int i = 0; i <= hexTextBox.Text.Length - 2; i += 2)
{
Sb.Append(Convert.ToString(Convert.ToChar(Int32.Pa rse(HexString.Substring(i, 2), System.Globalization.NumberStyles.HexNumber))));
}
return Sb.ToString();
}

I don't understand why you are saying your program "can't process" a string of this length. If it is being held in "HexString" then it is processing it.

You asked how to carve up a string and put it back together again. You've been shown that. So... What is your question?

my program will hang when it processes that much of a string. so i'm thinking of dividing the whole string up and processing.

then at the end of the day, combine all the processed strings.

Joining is easy, just use the Append method in the StringBuilder class. For splitting you can call the Split method on the ToString value of the StringBuilder.
P.S Because StringBuilder is fast you may not need to split the text into separate buffers after all.
