我有一个ASP.NET web服务旧建（使用的.asmx）文件。我需要使用sodium - 不幸的是它在加载依赖l​​ibsodium.dll文件失败。什么我做了错误的任何想法？

I have an old webservice build on ASP.NET (using .asmx) files. I need to use sodium - unfortunately it fails while loading the dependent libsodium.dll file. Any ideas about what I make wrong?

• 我走过的NuGet添加libsodium。

• I have added libsodium through NuGet.

我已经改名为64位DLL为libsodium.dll（和其他命名约定太）。

I have renamed the 64 bit DLL to "libsodium.dll" (and other naming conventions too).

我曾尝试libsodium.dll直接引用，但VS拒绝它（不是一个有效的DLL）。所以我将它称为内容，而不是与复制到输出。

I have tried to reference libsodium.dll directly but VS rejects it (not a valid DLL). So I have added it as "content" instead with "copy to output".

建筑，我可以看到该网站/ bin文件夹包含sodium.dll（.NET程序集），并libsodium后。

After building I can see that the website/Bin folder contains both sodium.dll (the .NET assembly) and libsodium.

当我尝试使用libsodium我得到：

When I try to use libsodium I get:

错误2015年2月2日11：14：27118 13798ms [41] CabinetService doRequest - 捉住：为Sodium.SodiumCore'的类型初始值引发了异常。System.TypeInitializationException：对于Sodium.SodiumCore'的类型初始值引发了异常。 ---> System.DllNotFoundException：无法加载DLLlibsodium.dll：指定的模块找不到。 （异常来自HRESULT：0x8007007E）   在DynamicDllInvokeType.sodium_init（）   在Sodium.SodiumCore..cctor（）   ---内部异常堆栈跟踪的结尾---   在Sodium.SodiumCore.LibraryName（）   在Sodium.SecretBox.Create（字节[]消息，字节[]的随机数，字节[]键）   在Macaroons.SecretBoxCryptoAlgorithm.Encrypt（字节[]键，字节[]明文）在C：\\项目\\ Macaroons.Net \\ Macaroons.Net \\ SecretBoxCryptoAlgorithm.cs：58行

所以它不能找到libsodium.dll，即使是在Bin文件夹。我也尝试删除的sodium里后，我得到了一个运行时错误的依赖性说：sodium丢失 - 当我重新添加它，该错误消失了，我得到了一个以上的，而不是（指示sodium正确加载）。

So it cannot find "libsodium.dll" even though it is in the Bin folder. I did also try to remove the dependency on "sodium" where after I got a runtime error saying "sodium" is missing - when I re-added it, that error disappeared and I got the one above instead (indicating the "sodium" loads correctly).

于是我在打开网页的影子文件夹C：\\ WINDOWS \\ Microsoft.NET \\框架\\ v4.0.30319 \\临时ASP.NET文件\\ cabinetservice并搜索钠。唯一的结果就是在一些子文件夹sodium.dll。没有libsodium.dll。

So I open up the website shadow folder in "C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\cabinetservice" and search for "sodium". The only result is "sodium.dll" in some subfolder. There is no "libsodium.dll".

因此​​很明显，创建该网站的卷影副本时ASP.NET忽略libsodium.dll文件。

So apparently ASP.NET ignores the "libsodium.dll" file when creating the shadow copy of the website.

我也试图加入libsodium.dll（32位）到C：\\ Windows \\ System32下和libsodium.dll（64位）到C：\\ WINDOWS \\ SysWOW64中。同样的结果。

I have also tried adding the libsodium.dll (32 bit) to C:\Windows\System32 and libsodium.dll (64 bit) to C:\Windows\SysWOW64. Same result.

我试图C：\\ WINDOWS \\ Microsoft.NET \\装配\\ GAC_32 \\ libsodium和C：\\ WINDOWS \\ Microsoft.NET \\装配\\ GAC_64 \\ libsodium。同样的结果。

And I have tried C:\Windows\Microsoft.NET\assembly\GAC_32\libsodium and C:\Windows\Microsoft.NET\assembly\GAC_64\libsodium. Same result.

我怎样才能让ASP.NET知道依赖？

How can I make ASP.NET aware of the dependency?

推荐答案

原来，ASP.NET不会使托管DLL如libsodium.dll和libsodium-64.dll的卷影副本。

It turns out that ASP.NET doesn't make shadow copies of unmanaged DLLs such as libsodium.dll and libsodium-64.dll.

Sodium.dll（托管code）试图从任一相同的目录Sodium.dll的卷影副本（这是行不通的）加载的DLL - 或一些地方在PATH环境变量的目录

Sodium.dll (the managed code) tries to load the DLLs from either the same directory as the shadow copy of Sodium.dll (which is not going to work) - or some where in the PATH environment variable's directories.

我的解决方案是之前调用任何钠code添加的AppDomain \\ bin目录的路径：

My solution was to add the AppDomain \Bin directory to the path before calling any Sodium code:

// Make it possible to load unmanaged libsodium DLLs that .NET does not make shadow copies of. // -> Simply point the "path" variable to the Bin directory. string path = Environment.GetEnvironmentVariable("PATH"); string binDir = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Bin"); Environment.SetEnvironmentVariable("PATH", path + ";" + binDir);
