find and replace string.

[joker769]

hi, im having a similar problem but i need one that replaces letters, and in c# format... does anyone know how to do that? ... it takes the concept of a custom encrypter, if you ve seen a game c# then what is usually

if (Control == ???)
{
 <act>
}

ive tried to make it where it does this

if (text == A || text == a)
{
newtext == r
}

[phoenix911]

post what the error is first of all...

but looking at that... you're comparing a string (text) to a variable (A or a)

if (text == A || text == a)
{
newtext == r
}

so instead add quotes ("") around the A and a.. which will compare the text to the strings A and a.

if (text == "A" || text == "a")
{
newtext == "r"
}

or

if you're working with chars, then add single quotes ('') around the A and a...
eg

if (text == 'A' || text == 'a')
{
newtext == 'r'
}

i couldnt remember how i first set it to where that was effective, although i do understand that, its not the right direction i was going, that was my first try but after it just took every letter after it had already done that and did it again making it impossible to decode "easily".. i decided to g along with this

using System;
using System.IO;
using System.Text.RegularExpressions;

            string Command = Console.ReadLine();
            string[] Cmd = Command.Split(' ');
            string input = (Cmd[0]);

            // Use Regex.Replace to Replace the pattern in the input.
            // ... The pattern N.t indicates three letters, N, any character, and t.

}

that is my entire code so if anyone wants to perfect it be my guest... but i still have one glitch...what this program is designated to do is create a text file that gets writen by text that you input into the console, but it only works once then shuts down... i dont remember how to make it start over but thats the lease of it, the other glitch is that when creating the file it wont work unless i specify MY exact location which is dffrent then people whom i work with who need to create new coded texts. please help me fix these error =(

[phoenix911]

instead of specifying a hard coded path to the desktop use this

My.Computer.FileSystem.SpecialDirectories.Desktop

this is VB... but im sure C# has something similar or exactly the same, havent needed to do something like that in c# yet... just vb...

so try and port that to C# and it would work like a dream...

and if you want it to continue running until you are done...

use a loop

char done = 'N'
do
{

//code
//ask user if they are done
done = ans //(which is either y or n, is up to you)
}
while(done.toUpper() == 'Y')

there are several ways to loop it :)

hope this helps

[joker769]

that way i can understand but its not reading most of the varibles in the code... for example My. is not found (does not exist in current text) , ans and toupper are not reading either.... ive never used char before or buffer, it just seems pointless to me.

[phoenix911]

here is the C# code for desktop

Environment.SpecialFolder.Desktop

and for the char to get it to upper...

do this

done.ToString().ToUpper()
