How to use google-diff-match-patch C# library?

I am looking at http://code.google.com/p/google-diff-match-patch/ and have downloaded the file. When I look at it is 2 files

DiffMatchPatch.cs
DiffMatchPatchTest.cs

When I try to make a new object of DiffMatchPatch.cs I have to pass in some operation and string text.

http://neil.fraser.name/software/diff_match_patch/svn/trunk/demos/demo_diff.html

In the demo they cross ou开发者_如何学运维t the words that are different and that is what I am trying to achieve.

I am trying to compare 2 blocks of text on the server side finds the differences and send a email to the user with the file block of text to them like the end result is in the demo that I posted above.

So does anyone have a tutorial on how to use the C# version?

For reference, this is really easy:

var dmp = new diff_match_patch();
var diffs = dmp.diff_main(text1, text2);
var html = dmp.diff_prettyHtml(diffs);

Implementation with current version(2.1.0) would look like this

var dmp = DiffMatchPatchModule.Default;
var diffs = dmp.DiffMain(text1, text2);
var html = dmp.DiffPrettyHtml(diffs);

For anyone who came across this thread because of the title and expected an explanation on how to use the Google Diff-Match-Patch algorithm via the https://github.com/pocketberserker/Diff.Match.Patch library found on NuGet, to create a diff string, so he can send the change somewhere (e.g. via websocket) and restore it at the destination based on the old value and the diff string, that would work like this:

var oldValue = "Test old text.";
var newValue = "Test new text.";

// create diff string
var dmp = DiffMatchPatch.DiffMatchPatchModule.Default;
var diffs = dmp.DiffMain(oldValue, newValue);
var srcDelta = dmp.DiffToDelta(diffs);

// restore from diff
var dmp = DiffMatchPatch.DiffMatchPatchModule.Default;
var dstDelta = dmp.DiffFromDelta(oldValue, srcDelta);
var restoredNewValue = dmp.DiffText2(dstDelta);
