Question

我想计算一个比较两个文档的unified diff。（差异是用电子邮件发送的，维基百科说统一差异是最好的纯文本差异格式。）

Team Foundation有一个command line interface做那个

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

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

很棒，但出于通常的原因，我宁愿使用库而不是启动外部进程。

在搜索MSDN时，我发现Team Foundation有一个.NET库Microsoft.TeamFoundation.VersionControl。但是，文档没有给出任何计算差异的例子。

如何使用Team Foundation库计算统一差异？

编辑：我试过这个方法 Difference.DiffItems但它不起作用 - 文件diff.txt留空。

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

请尝试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;
        }

猜猜不可能:(您只能通过命令行tf.exe执行此操作。
