Comparing two files

darma teja

14yAsked May 23, 2012, 8:38 AM1.5kVisual Basic .NET

Hi,

I have two files.

In 1st file:

in 2nd file:

[FileVersion]

GUID={F5C91E25-E904-4AD0-AA6A-41FD0A5A12E4}

Version=9

MarkupVersion=0

DisplayName=XML-MDB-Satzweise-nxt

FileExtension=*.xml

How can i compare two files Based on GUID. If these two GUID's are equal than two files are the same.

Thanks

Darma

Assuming there's only one GUID in each file or it's just the first one you need to match, then this is easily done using a regular expression.

Here's some sample code:

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

class Test
{
static void Main()
{
string regExp =
@"(?i)\b" +
@"[0-9A-F]{8}-" +
@"[0-9A-F]{4}-" +
@"[0-9A-F]{4}-" +
@"[0-9A-F]{4}-" +
@"[0-9A-F]{12}" +
@"\b";

string text = File.ReadAllText("darma.xml");
string guid = Regex.Match(text, regExp).Value;
Console.WriteLine(guid);

string text2 = File.ReadAllText("darma.ini");
string guid2 = Regex.Match(text2, regExp).Value;
Console.WriteLine(guid2);

if (guid == guid2)
Console.WriteLine("Files are the same");
else
Console.WriteLine("Files are not the same");
Console.ReadKey();
}
}
