如何使用团队基础的库来计算标准差异？ [英] How to use Team Foundation's library to calculate unified diff?

问题描述

我要计算一个统一差异比较两个文件。 （该差异是走在一封电子邮件，和维基百科说，统一的差异是最好的纯文本差异格式。）

团队基础具有命令行界面做

 ＆GT; TF差异/格式：统一alice.txt bob.txt
 - 爱丽丝开始她的脚，
+鲍勃开始了她的脚，
 

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

辉煌，但我宁愿使用的库比启动外部过程中，通常的原因。

在搜索MSDN，我发现球队基金会有一个.NET库<一href="http://msdn.microsoft.com/en-us/library/microsoft.teamfoundation.versioncontrol.client(v=vs.80).aspx"相对=nofollow> Microsoft.TeamFoundation.VersionControl 。但是，文件并未给出计算差异的任何实例。

我如何计算出一个统一的差异与团队基础库？

编辑：我试过的方法  <一href="http://msdn.microsoft.com/en-us/library/microsoft.teamfoundation.versioncontrol.client.difference.aspx"相对=nofollow> Difference.DiffItems ，但没有奏效，文件 diff.txt 是空的。

之前=

  VAR @C：\ alice.txt;
后= @C：\ bob.txt变种;

VAR路径= @C：\ diff.txt;
使用（VAR W =新的StreamWriter（路径））
{
    VAR的选择=新DiffOptions（）;
    options.OutputType = DiffOutputType.Unified;
    options.StreamWriter = W;

    Difference.DiffFiles（
    之前，FileType.Detect（前，空）
    之后，FileType.Detect（后为空），
    选项​​）;
}

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

解决方案

猜猜这是不可能的:(只能从与 tf.exe 在命令行中执行此操作。

I want to calculate a unified diff comparing two documents. (The diff is to go in an email, and Wikipedia says unified diff is the best plain text diff format.)

Team Foundation has a command line interface do that

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

(Example files at https://gist.github.com/hickford/5656513)

Brilliant, but I'd rather use a library than start an external process, for the usual reasons.

Searching MSDN, I found Team Foundation has a .NET library Microsoft.TeamFoundation.VersionControl. However, the documentation didn't give any examples of calculating a diff.

How do I calculate a unified diff with the Team Foundation library?

Edit: I tried the method Difference.DiffItems but it didn't work—the file diff.txt was left empty.

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));

解决方案

Guess it's not possible :( You can only do this from the command line with tf.exe.
