Libsodium-net-无法加载DLL'libsodium.dll [英] Libsodium-net - Unable to load DLL 'libsodium.dll

问题描述

我通过NuGet安装了Libsodium-net，并且可以将Sodium包含在我的课程中，但是当我尝试运行它时，我得到了

I installed Libsodium-net through NuGet and am able to include Sodium in my classes, but when I try to run it, I get

System.DllNotFoundException'发生在Sodium.dll中，但未在用户代码中处理

An exception of type 'System.DllNotFoundException' occurred in Sodium.dll but was not handled in user code

其他信息：无法加载DLL libsodium.dll：指定模块无法找到了。 （来自HRESULT的异常：0x8007007E）

Additional information: Unable to load DLL 'libsodium.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

我只是尝试运行gitbooks文档
https://bitbeans.gitbooks.io/libsodium-net/content/password_hashing/index.html

I am just trying to run the sample code from the gitbooks documentation https://bitbeans.gitbooks.io/libsodium-net/content/password_hashing/index.html

const string PASSWORD = "Correct Horse Battery Staple";
const string SALT = "qa~t](84z<1t<1oz:ik.@IRNyhG=8q(o";
const long OUTPUT_LENGTH = 512;

//this will produce a 512 byte hash
var hash = PasswordHash.ScryptHashBinary(PASSWORD, SALT,      PasswordHash.Strength.Medium, OUTPUT_LENGTH);

推荐答案

我遇到了同样的问题，并使用

I had the same problem and solved it using Jørn Wildt's answer given here.

事实证明，ASP .NET不会对非托管DLL（例如libsodium.dll和libsodium-64.dll）进行卷影副本。

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

Sodium.dll（托管代码）尝试加载来自与Sodium.dll的卷影副本相同的目录中的DLL（将不起作用）-或PATH环境变量目录中的某些目录中的DLL。

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.

我的解决方案是在调用任何钠代码之前将AppDomain \Bin目录添加到路径：

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

string path = Environment.GetEnvironmentVariable("PATH");
string binDir = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Bin");
Environment.SetEnvironmentVariable("PATH", path + ";" + binDir);

如鲁本对答案的评论；我在 Global.asax 的 Application_Start 方法中添加了上面的代码。

As Reuben commented on the answer; I added the above code in my Application_Start method of my Global.asax.
