如何获取当前正在执行的 DLL 的位置？

我有一个配置文件，我需要加载的一部分，我写的 dll 的执行。

我遇到的问题是，当应用程序运行时，我放置 dll 和 config 文件的位置不是“当前位置”。

例如，我将 dll 和 xml 文件放在这里:

程序文件 MicrosoftTeamFoundationServer2010应用层 Web 服务箱插件

但是如果我尝试像下面这样引用 xml 文件(在我的 dll 中) :

XDocument doc = XDocument.Load(@".\AggregatorItems.xml")

那么 . AggreatorItems.xml翻译成:

C: windows system 32 inetsrv AgregatorItems.xml

因此，我需要找到一种方法(我希望)来了解当前正在执行的 dll 位于何处。基本上我在找这个:

XDocument doc = XDocument.Load(CoolDLLClass.CurrentDirectory+@"\AggregatorItems.xml")

最佳答案

You are looking for System.Reflection.Assembly.GetExecutingAssembly()

string assemblyFolder = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
string xmlFileName = Path.Combine(assemblyFolder,"AggregatorItems.xml");

Note:

The .Location property returns the location of the currently running DLL file.

Under some conditions the DLL is shadow copied before execution, and the .Location property will return the path of the copy. If you want the path of the original DLL, use the Assembly.GetExecutingAssembly().CodeBase property instead.

.CodeBase contains a prefix (file:\), which you may need to remove.

Reflection is your friend, as has been pointed out. But you need to use the correct method;

Assembly.GetEntryAssembly()     //gives you the entrypoint assembly for the process.
Assembly.GetCallingAssembly()   // gives you the assembly from which the current method was called.
Assembly.GetExecutingAssembly() // gives you the assembly in which the currently executing code is defined
Assembly.GetAssembly( Type t )  // gives you the assembly in which the specified type is defined.

In my case (dealing with my assemblies loaded [as file] into Outlook):

typeof(OneOfMyTypes).Assembly.CodeBase

Note the use of CodeBase (not Location) on the Assembly. Others have pointed out alternative methods of locating the assembly.

If you're working with an asp.net application and you want to locate assemblies when using the debugger, they are usually put into some temp directory. I wrote the this method to help with that scenario.

private string[] GetAssembly(string[] assemblyNames)
{
string [] locations = new string[assemblyNames.Length];




for (int loop = 0; loop <= assemblyNames.Length - 1; loop++)
{
locations[loop] = AppDomain.CurrentDomain.GetAssemblies().Where(a => !a.IsDynamic && a.ManifestModule.Name == assemblyNames[loop]).Select(a => a.Location).FirstOrDefault();
}
return locations;
}

If you can't change the source code, or redeploy, but you can examine the running processes on the computer use Process Explorer. I written a detailed description here.

It will list all executing dlls on the system, you may need to determine the process id of your running application, but that is usually not too difficult.

I've written a full description of how do this for a dll inside IIS - http://nodogmablog.bryanhogan.net/2016/09/locating-and-checking-an-executing-dll-on-a-running-web-server/

Try this

System.IO.Path.GetDirectoryName(new System.Uri(System.Reflection.Assembly.GetExecutingAssembly().CodeBase).LocalPath)
