As i was reading from other forums about this problem, i didn't find any clear solutin to it.
I'm trying to read line by line a file.When the line matches a certain group of characters, i want to rewrite the whole line with another modifyied line, or to modify a certain group of characters from that line.
Here is the code that should rewrite that line:
const String FILE_NAME = @"C://my.txt";
String s = "Text to replace with";
StreamReader ad = File.OpenText(FILE_NAME);
String input = null;
while ((input = ad.ReadLine()) != null)
{
if (input==s)
{/*write a code that rewrite the whole line or
modify a group of characters from that line*/
}
}
Example(if the file contains the lines below, and the line that i'm looking for, is containing the string "Text2"),
Text1
Text2
Text3
The procedure should modify the file this way:
Text1
This line was modifyied
Text3
I will apreciate if you could give me a solution, in this context.
