从svn更新之前，请检查本地目录是否是工作副本 [英] Check local directory is a working copy before updating from svn

问题描述

我正在使用c#编程提取svn存储库.我已经将Sharpsvn dll添加到我的项目中，并编写了以下代码

I am working on extracting svn repository using c# programming. I have added sharpsvn dll to my project and wrote following code

string localFolder= @"C:\Users\Desktop\LocalFolder\Dev\Websites\Service";
SvnClient client = new SvnClient();

SvnUriTarget target = new SvnUriTarget(@"http://svn.user.com/svn/websites/Branches/InternalServices");

SvnInfoEventArgs info;

client.GetInfo(target, out info);

//Specify the repository root as Uri
//Console.WriteLine("Repository version: {0}", info.Revision);
Console.WriteLine("Started checking out. Please wait few minutes");

client.CheckOut(target, localFolder);                   
//client.Update(localFolder);

我已经使用'client.checkout'方法签出，并且可以使用'client.update'方法进行更新.

I have checked out using 'client.checkout' method and i can update using 'client.update' method.

假设我的机器上有文件夹服务".我最初是使用"client.checkout"将文件/文件夹检出到该文件夹​​中.

Let say i have folder 'services' in my machine. I am checking out files/folders initially using 'client.checkout' to this folder.

下次运行程序时，它应该自动更新而无需检出.我怎么知道服务文件夹是否已经签出一次，现在应该更新了?

Next time when i run the program it should update automatically without checkout. How can i know if the service folder has already done a checkout once and now it should update?

推荐答案

您可以像这样确定目录是否为工作副本:

You can determine whether a directory is a working copy like this:

public static bool IsWorkingCopy(string path)
{
    using (var client = GetSvnClient())
    {
        var uri = client.GetUriFromWorkingCopy(path);
        return uri != null;
    }
}
