3 questions... (string related)

[Guest]

Hi,

I'm writing a C# Windows Application and i have 3 questions:

1. I have a string which i want to write into file but i want to write it in
ASCII format, how can i do it?

2. I need my string to be 120 chars length, incase it's less then 120 chars,
i need to fill it with spaces, is there better way to do it then:

while(str.length<120)
{
str=str+" ";
}

3.I need to concatenate few string into one string, but i need to keep the
orginal order, my string contains numbers, english letters, hebrew letters
and white spaces. when i'm using str=str1+str2 the order is mixed (the hebrew
and english letters along with the numbers), is it better way to concatenate
my strings to one string that keep the order of my strings?

Thanks,
Gidi.

Hi Gidi,

for your first question (set the encoding information):

StreamWriter sw = new StreamWriter(string path, true,
System.Text.Encoding.ASCII);

for your second question (use PadRight() method):

string mystring = "Hello";
if(mystring.Length < 120)
mystring.PadRight(120, new char(' '));

For your third question, use an ArrayList and insert
the strings in the right order, after that concate
them by foreach with +=

Cheers

if(mystring.Length < 120)
mystring.PadRight(120, new char(' '));

The first line is unnecessary...

if(mystring.Length < 120)

The first line is unnecessary...

And the second line should be

mystring = mystring.PadRight(120, ' ');

Hi Lars,

Thanks for your fast answer.
I tried to use:
StreamWriter sw=new StreamWriter(string path,true,System.Text.Encoding.ASCII);
and now instead of hebrew letters i see in the file ???? (before that i saw
it as gibberish), do u have any idea why?

Thanks Again,
Gidi.

I wonder if it's because the Hebrew character set does not fit into the
"standard" ASCII range i.e. from 32 to 127...?

And the second line should be

mystring = mystring.PadRight(120, ' ');

Or preferrably just

mystring = mystring.PadRight(120);

Space is used as the default character to pad with
