2.diffengine

簡介：

功能強大，

缺點：文本每行不能超過1024個字符

DifferenceEngine.DiffList_TextFile sourceFile null;
DifferenceEngine.DiffList_TextFile destinationFile = null;

sourceFile = new DifferenceEngine.DiffList_TextFile("1.txt");
destinationFile = new DifferenceEngine.DiffList_TextFile("2.txt");

DifferenceEngine.DiffEngine engine = new DifferenceEngine.DiffEngine();
engine.ProcessDiff(sourceFile,destinationFile, DifferenceEngine.DiffEngineLevel.FastImperfect);
ArrayList diffLines = engine.DiffReport();
foreach (DifferenceEngine.DiffResultSpan span in diffLines)
{
switch (span.Status)
{
case ifferenceEngine.DiffResultSpanStatus.NoChange:
//沒改變
break;
case DifferenceEngine.DiffResultSpanStatus.AddDestination:
//新增的
break;
case DifferenceEngine.DiffResultSpanStatus.DeleteSource:
//已刪除的
break;
case DifferenceEngine.DiffResultSpanStatus.Replace:
//修改的
break;
default:
// 默認
break;

}

}

獲取新增內容示例：

string str = ((DifferenceEngine.TextLine)(destinationFile.GetByIndex(span.DestIndex))).Line;
