c# patch_toText + patch_fromText doesn't work

```
What steps will reproduce the problem?
1. Run this code with C# version

string text1 = "I like football\nI like baseball";
string text2 = "I like football\nI love baseball";

diff_match_patch dmp = new diff_match_patch();
List diff = dmp.diff_main(text1, text2);

List patchList = dmp.patch_make(diff);

string patchText = dmp.patch_toText(patchList);
List patchList2 = dmp.patch_fromText(patchText);
object[] ob = dmp.patch_apply(patchList2, text1);
string patchedStr = ob[0].ToString();

if (patchedStr != text2)
{
// patch didn't work
}

What is the expected output? What do you see instead?
patchedStr != text2

Beginne damit, die gemeldete C#-Reproduktion mit diff_main, patch_make, patch_toText, patch_fromText und patch_apply auszuführen. Vergleiche patchedStr mit text2 und verfolge den Roundtrip der Patch-Serialisierung; das Issue ist erledigt, wenn patch_fromText Patches erzeugt, die patch_apply erfolgreich anwendet, sodass patchedStr gleich text2 ist.
