透過 SharpSvn 取出某路徑的所有檔案(SVN Export)

前言

透過 SharpSvn 來 Export 時，在大多數的電腦上都沒問題的。
但在某台電腦中，在 Export 到某個檔案時，卻會將整個程式關畢，而那個檔名原本是 FRM10009.docx ，
卻會變成 svn-444AA7Ff 或是 svn-54A3A7Da 等 svn- 開頭的檔案。

研究

然而透過程式直接使用 SvnClient.Write 卻是可以的，所以只好改用一個一個檔案來取的方式。
以下為 Console App 程式。

#region 變數宣告
string svnId = "svn userid",
	   svnPwd = "svn userpwd",
	   svnPath = "SVNPath",
	   tempPath = "ExportPath"

#endregion

//Delete Local all files and folders
var di = new DirectoryInfo(tempPath);
foreach (FileInfo file in di.EnumerateFiles())
{
	file.Delete();
}
foreach (DirectoryInfo dir in di.EnumerateDirectories())
{
	dir.Delete(true);
}

var client = new SvnClient();
client.Authentication.DefaultCredentials = new NetworkCredential(svnId, svnPwd);
SvnUriTarget folderTarget = new SvnUriTarget(svnPath);
Export(client, folderTarget, tempPath);
Console.WriteLine($"{new string('=', 30)}");

/// <summary>
/// 改用遞迴方式來一個一個取出檔案
/// </summary>
/// <param name="client"></param>
/// <param name="svnTarget"></param>
/// <param name="folderPath"></param>
private static void Export(SvnClient client, SvnTarget svnTarget, string folderPath)
{
	Console.WriteLine($"{new string('=', 6)}{folderPath}{new string('=', 6)}");
	var phyFolderPath = Path.Combine(folderPath, svnTarget.FileName);
	if (!Directory.Exists(phyFolderPath))
	{
		Directory.CreateDirectory(phyFolderPath);
	}
	Collection<SvnListEventArgs> listResults;
	if (client.GetList(svnTarget, out listResults))
	{
		foreach (SvnListEventArgs item in listResults)
		{
			switch (item.Entry.NodeKind)
			{
				case SvnNodeKind.File:
					var phyFilePath = Path.Combine(phyFolderPath, item.Path);
					using (FileStream fileStream = File.Open(phyFilePath, FileMode.OpenOrCreate))
					{
						var fileTarget = new SvnUriTarget(item.Uri);
						client.Write(fileTarget, fileStream);
					}
					Console.WriteLine($"{item.Path}");
					break;

				case SvnNodeKind.Directory:
					if(Uri.Compare(item.BaseUri, item.Uri,
							UriComponents.Host | UriComponents.PathAndQuery,
							UriFormat.SafeUnescaped, StringComparison.OrdinalIgnoreCase)!=0)
					{
						Console.WriteLine($"{new string('*', 8)}SubFolder:Start:{item.Name}{new string('*', 8)}");
						//child folder
						var childTarget = new SvnUriTarget(item.Uri);
						Export(client, childTarget, phyFolderPath);
						Console.WriteLine($"{new string('*', 8)}SubFolder:End:{item.Name}{new string('*', 8)}");
					}
					break;
				default:
					break;
			}
		}
	}
	else
		throw new Exception("Failed to retrieve files via SharpSvn");
}
