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。

这是一个VB。John bly代码的NET移植。Visual Basic不区分大小写，所以他的几个变量名会与类型名发生冲突。

Public Shared ReadOnly Property AssemblyDirectory() As String
    Get
        Dim codeBase As String = Assembly.GetExecutingAssembly().CodeBase
        Dim uriBuilder As New UriBuilder(codeBase)
        Dim assemblyPath As String = Uri.UnescapeDataString(uriBuilder.Path)
        Return Path.GetDirectoryName(assemblyPath)
    End Get
End Property

这应该可以工作，除非程序集是影子复制的:

string path = System.Reflection.Assembly.GetExecutingAssembly().Location

如果路径包含“#”符号，则会得到不正确的目录。 所以我使用了John bly答案的一个修改，那就是组合UriBuilder。Path和UriBuilder。片段:

public static string AssemblyDirectory
{
    get
    {
        string codeBase = Assembly.GetExecutingAssembly().CodeBase;
        UriBuilder uri = new UriBuilder(codeBase);
        //modification of the John Sibly answer    
        string path = Uri.UnescapeDataString(uri.Path.Replace("/", "\\") + 
          uri.Fragment.Replace("/", "\\"));
        return Path.GetDirectoryName(path);
     }
}

其实很简单:

var dir = AppDomain.CurrentDomain.BaseDirectory;

我发现我的解足够检索位置。

var executingAssembly = new FileInfo((Assembly.GetExecutingAssembly().Location)).Directory.FullName;
