这应该可以工作:

ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
Assembly asm = Assembly.GetCallingAssembly();
String path = Path.GetDirectoryName(new Uri(asm.EscapedCodeBase).LocalPath);

string strLog4NetConfigPath = System.IO.Path.Combine(path, "log4net.config");

我使用它来部署DLL文件库以及一些配置文件(这是从DLL文件中使用log4net)。

var assembly = System.Reflection.Assembly.GetExecutingAssembly();
var assemblyPath = assembly.GetFiles()[0].Name;
var assemblyDir = System.IO.Path.GetDirectoryName(assemblyPath);

我在过去的NUnit中得到了相同的行为。默认情况下，NUnit将程序集复制到临时目录。你可以在NUnit设置中改变这种行为:

也许TestDriven。NET和MbUnit GUI有相同的设置。

从。net framework 4.6 / .net core 1.0开始，现在有了一个AppContext。BaseDirectory，它应该给出与AppDomain.CurrentDomain相同的结果。除了AppDomains不是.net core 1的一部分。X /.net标准x的API。

AppContext.BaseDirectory

编辑:文档现在甚至声明:

在. net 5.0及更高版本中，对于捆绑的程序集，返回的值是主机可执行文件的包含目录。

事实上,组装。定位医生医生说:

在. net 5.0及更高版本中，对于捆绑的程序集，返回的值是空字符串。

我一直在用汇编。用CodeBase代替Location:

Assembly a;
a = Assembly.GetAssembly(typeof(DaoTests));
string s = a.CodeBase.ToUpper(); // file:///c:/path/name.dll
Assert.AreEqual(true, s.StartsWith("FILE://"), "CodeBase is " + s);
s = s.Substring(7, s.LastIndexOf('/') - 7); // 7 = "file://"
while (s.StartsWith("/")) {
    s = s.Substring(1, s.Length - 1);
}
s = s.Replace("/", "\\");

它一直在工作，但我不再确定它是100%正确的。http://blogs.msdn.com/suzcook/archive/2003/06/26/assembly-codebase-vs-assembly-location.aspx的网页上写着:

"The CodeBase is a URL to the place where the file was found, while the Location is the path where it was actually loaded. For example, if the assembly was downloaded from the internet, its CodeBase may start with "http://", but its Location may start with "C:\". If the file was shadow-copied, the Location would be the path to the copy of the file in the shadow copy dir. It’s also good to know that the CodeBase is not guaranteed to be set for assemblies in the GAC. Location will always be set for assemblies loaded from disk, however."

您可能希望使用CodeBase而不是Location。
