Let's say I have strings :
Oi, meu nome é ítalo and Olá, meu nome é ítalo
How to generate a + result - like this:
Hi , my name is Italo
Hello , my name is Italo
The system should mark somehow the part of string which is different.
Before anyone asks what I've done, I mean I have no idea how to do it, so I posted the question.
I just started to do the code here, but I can not stop it for now, it follows the initial code:
private void Comparar(RichTextBox rtb1, RichTextBox rtb2)
{
rtb1.ForeColor = Color.Black;
rtb1.BackColor = Color.Empty;
string[] texto1 = rtb1.Text.Split(' ');
string[] texto2 = rtb2.Text.Split(' ');
int removidas = 0;
for (int i =0 ; i < texto1.Length;i++)
{
if (texto2.Length > i - removidas)
if (texto1[i] != texto2[i-removidas])
{
rtb1.Select(rtb1.Text.IndexOf(texto1[i], i), texto1[i].Length);
rtb1.SelectionBackColor = Color.Orange;
removidas++;
}
}
}
Obviously it's still just a prototype, but you can start. The result was as follows:
You can use a library that manages textual comparison.
The google-diff-match-patch library is available in a number of languages .
To use the C # version, simply download the latest version of the diff_match_patch.zip file and add the DiffMatchPatch.cs file to your project.
The comparison can be made as follows:
string text1 = "Oi, tudo bem?";
string text2 = "Olá, tudo bem?";
var dmp = new diff_match_patch();
var diffs = dmp.diff_main(text1, text2);
var html = dmp.diff_prettyHtml(diffs);
