String Format help

[Matt]

string format formula to write a text file
below is not working for me
pos 1 to 10 name
pos 15 to 30 lastname
pos 45 to 75 job
Adam smith programmer

string fmt = "{1,10}{15-30}{45,75}" // is not working any help ?
sb.Append(strin g.Format(fmt,"A dam","smith","p rogrammer"));

Hi Matt,

To start with, you're using the String.Format function all wrong. Take a
look at the following:

http://msdn.microsoft.com/library/de...ormattopic.asp

You can only pass one string to the function.

Assuming that you're not working with literal strings, you should be able to
use the String.PadRight () method to build you string. Example:

string firstName = "Adam";
string lastName = "Smith";
string job = "programmer ";

string together = firstName.PadRi ght(10) + lastName.PadRig ht(30) +
job.PadRight(75 );

This worked for me:
Console.WriteLi ne("123456789a1 23456789b123456 789c123456789d1 23456789e123456 7
89f123456789g12 3456");
Console.WriteLi ne("{0,-10}....{1,-15}............ ...{2,-30}|", "Adam",
"Smith","Progra mmer");
In each {n,m}, the first number is the position of the parameter, the second
number is the length of the field, negative meaning padded on the right
(positive numbers would pad on the left).

Nonsense. You can pass as many parameter as you like to String.Format,
and any of them can be strings.

Thanks all
Anyway to option explicit this formula
what i mean with that is
Console.WriteLi ne("{0,-10}....{1,-15}............ ...{2,-30}|", "Adam",
"Smith","Progra mmer");
I like name( in this case Adam 4 char )
what happens if the name is more that 4 char like (GordonGongolaz )
I am happy if it does not push others and just put GordonGong

I am Soooooooo confused!?!?
The link you posted CLEARLY shows multiple overloads for string.Format()

His problem was a badly structured format string. But James has already explained that.
Assuming that you're not working with literal strings, you should be able to use the
String.PadRight () method to build you string. Example:

string firstName = "Adam";
string lastName = "Smith";
string job = "programmer ";

string together = firstName.PadRi ght(10) + lastName.PadRig ht(30) +
job.PadRight(75 );

Uhhhh. That doesn't work either.
job.PadRight(75 );
will create string with a minimum Length of 75, when he wanted a string spanning column 45 to 75

[Matt]

here is what i have
string fmt = "{0,-4}{1,-5}{2,-6}{3,-36}{4,-37}";
//start 0 to 4 write Adam // if the name is more than 4 just take 4
char dont pust other letters
//start 4 to 5 space
//start 6 to 35 LastName
//start 36 to 37 space
//start 38 to 75 job

sb.Append(strin g.Format(fmt,"A dam"," ","Gongodgozale s","
","CrapyProgram mer"));
sb.Append("\n") ;
myWriter.Writer (fileName,sb.To String());

Note ! lastname fails
{2,-6} fails it starts from 10th space on text file any idea?

[Kevin Spencer]

I stand corrected. D**n, I'm working too hard these days. Thanks for
pointing that out!

Hi Matt,

James has already given you the basic solution.
string.Format ("{0,-10}....{1,-15}............ ...{2,-30}|", "Adam","Smith", "Programmer ");
HOWEVER
If any of the columns can exceed it's assigned width, this will fail.
Here is a method that works, but it is a tad icky.
You need to use construct like this

string name = InputString.Pad Right(15).Subst ring(0,15);
It would be nice to just be able to use Substring, but that throws an exception if the string is
too short.
Try this to see the concept in action:

for(int i = 1; i < 45; i++)
{
string a = new string('a',i).P adRight(15,':') .Substring(0,15 );
string b = new string('b',i).P adRight(15,':') .Substring(0,15 );
string c = new string('c',i).P adRight(30,':') .Substring(0,30 );
string str = string.Format(" {0,-10}.....{1,-15}............ ...{2,-30}",a,b,c);
Console.WriteLi ne("{0}",str);
}
