如何使用Team Foundation的庫來計算統一差異？

Question

我想計算一個比較兩個文檔的unified diff。 （該差異是在一封電子郵件中去，和維基說統一差異是最好的純文本差異格式。）

團隊基礎具有command line interface做

> tf diff /format:unified alice.txt bob.txt 
- Alice started to her feet, 
+ Bob started to her feet, 

（在https://gist.github.com/hickford/5656513示例文件）

很棒，但我寧願使用一個庫，而不是啓動一個外部過程，通常的原因。

搜索MSDN，我發現Team Foundation有一個.NET庫Microsoft.TeamFoundation.VersionControl。但是，文檔沒有給出任何計算差異的例子。

如何計算Team Foundation庫的統一差異？

編輯：我試過的方法 Difference.DiffItems，但它沒有工作的diff.txt留下的空文件。

var before = @"c:\alice.txt"; 
var after = @"c:\bob.txt"; 

var path = @"c:\diff.txt"; 
using (var w = new StreamWriter(path)) 
{ 
    var options = new DiffOptions(); 
    options.OutputType = DiffOutputType.Unified; 
    options.StreamWriter = w; 

    Difference.DiffFiles(
    before, FileType.Detect(before, null), 
    after, FileType.Detect(after, null), 
    options); 
} 

Console.WriteLine(File.ReadAllText(path)); 

Answer 1

猜猜這是不可能的:(只可以用tf.exe做到這一點的命令行。

Answer 2

請嘗試DiffSegment

 var diff = Difference.DiffFiles(
     before, FileType.Detect(before, null), 
     after, FileType.Detect(after, null), 
     options); 

     while (diff != null){     
      //DO What you like with the diff(s) 
      diff = diff.Next; 
     }
