Question

我正在尝试创建一个可以浏览文件夹的网页。我已经在单独的解决方案中完成了这一切并且一切正常，但是当我尝试将它集成到解决方案中时，多个项目也引用了PostSharp我得到了这个错误：

 Unhandled exception (2.1.7.1, 32 bit, CLR 4.0, Release): System.IO.FileNotFoundException: Could not load file or assembly 'file:///C:\_projects\...\Libraries\SharpSvn\SharpSvn.dll' or one of its dependencies. The system cannot find the file specified.

    WRN: Assembly binding logging is turned OFF.
    To enable assembly bind failure logging, set the registry value         [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
    Note: There is some performance penalty associated with assembly bind failure logging.
    To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Answer 1

SharpSVN程序集可能无法加载，因为它引用了一些本机DLL（32位版本的SharpSvn-DB44-20-win32.dll和SharpSvn-Sasl21-23-win32.dll）。如果那些不在系统搜索路径中的某个位置 - 这通常是ASP.NET的情况 - 那么SharpSVN可能无法加载。

我有一个similar problem我的一个NuGet包不能在MVC网站上工作，因为原生DLL没有加载。将它们放在网站的bin文件夹中是不够的，因为bin文件夹既不在搜索路径上，也不在应用程序文件夹中。

尝试将以下方法添加到Global.asax.cs文件中的应用程序类，并从Application_Start()调用它：

public static void CheckAddBinPath()
{
    // find path to 'bin' folder
    var binPath = Path.Combine(new string[] { AppDomain.CurrentDomain.BaseDirectory, "bin" });
    // get current search path from environment
    var path = Environment.GetEnvironmentVariable("PATH") ?? "";

    // add 'bin' folder to search path if not already present
    if (!path.Split(Path.PathSeparator).Contains(binPath, StringComparer.CurrentCultureIgnoreCase))
    {
        path = string.Join(Path.PathSeparator.ToString(), new string[] { path, binPath });
        Environment.SetEnvironmentVariable("PATH", path);
    }
}

这会将您的bin文件夹添加到您的应用程序的系统搜索路径中，这应该允许SharpSvn找到它所依赖的本机DLL。只需确保文件实际存在 - 如果不是，则可能必须从SharpSvn分发中复制它们。

当然，我可能完全不合适。让我知道。

我写道：＆＃34;当我评论这个方法时，错误消失了：static void SVN_SSL_Override（object sender，SharpSvn.Security.SvnSslServerTrustEventArgs e）{e.AcceptedFailures = e.Failures; e.Save = true; }＆＃34;

不知道为什么但是有问题所以我删除了：

client.Authentication.Clear（）; client.Authentication.SslServerTrustHandlers + = new EventHandler（SVN_SSL_Override）; client.Authentication.DefaultCredentials = new NetworkCredential（＆＃34; ＆＃34;，＆＃34; ＆＃34;）;

和这个方法

static void SVN_SSL_Override（object sender，SharpSvn.Security.SvnSslServerTrustEventArgs e）{e.AcceptedFailures = e.Failures; e.Save = true; }＆＃34;

刚刚补充道：

client.Authentication.UserNamePasswordHandlers + = delegate（object obj，SharpSvn.Security.SvnUserNamePasswordEventArgs args） { args.UserName =＆＃34; ＆＃34 ;; args.Password =＆＃34; ＆＃34 ;; args.Save = true; };

现在可行。

System.IO.FileNotFoundException：无法加载文件或程序集。系统找不到SharpSvn.dll文件
