如何包括ASP.NET libsodium.net [英] How to include libsodium.net on ASP.NET
问题描述
我有一个ASP.NET web服务旧建（使用的.asmx）文件。我需要使用sodium.net - 不幸的是它在加载依赖libsodium.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.net - 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.net。
I have added libsodium.net 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.net后。
After building I can see that the website/Bin folder contains both sodium.dll (the .NET assembly) and libsodium.net.
当我尝试使用libsodium.net我得到：
When I try to use libsodium.net 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。

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.net里后，我得到了一个运行时错误的依赖性说：sodium.net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.net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.net" where after I got a runtime error saying "sodium.net" is missing - when I re-added it, that error disappeared and I got the one above instead (indicating the "sodium.net" 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);
