{. 1.1 APIs that return strings are very common. 对于可以自己部署的应用程序，这样未偿不是一个解决办法，然而，如果我们用的是虚拟空间，我们是没办法把注册PATH变量或者把我们自己的DLL拷到system32目录的。同时我们也不一定知道我们的Dll的物理路径。, DllImport里面只能用字符串常量，而不能够用Server.MapPath(@"~/Bin/Judge.dll")来确定物理路径。ASP.NET中要使用DllImport的，必须在先“using System.Runtime.InteropServices;”不过，我发现，调用这种"非托管Dll”相当的慢，可能是因为我的方法需要远程验证吧，但是实在是太慢了。经过一翻研究，终于想到了一个完美的解决办法首先我们用, 分别取得了LoadLibrary和GetProcAddress函数的地址，再通过这两个函数来取得我们的DLL里面的函数。我们可以先用Server.MapPath(@"~/Bin/Judge.dll")来取得我们的DLL的物理路径，然后再用LoadLibrary进行载入，最后用GetProcAddress取得要用的函数地址, 大家在实际工作学习C#的时候，可能会问：为什么我们要为一些已经存在的功能（比如Windows中的一些功能，C++中已经编写好的一些方法）要重新编写代码，C#有没有方法可以直接都用这些原本已经存在的功能呢？答案是肯定的，大家可以通过C#中的DllImport直接调用这些功能。    DllImport所在的名字空间 using System.Runtime.InteropServices;    MSDN中对DllImportAttribute的解释是这样的：可将该属性应用于方法。DllImportAttribute 属性提供对从非托管 DLL 导出的函数进行调用所必需的信息。作为最低要求，必须提供包含入口点的 DLL 的名称。    DllImport 属性定义如下：, 1、DllImport只能放置在方法声明上。 2、DllImport具有单个定位参数：指定包含被导入方法的 dll 名称的 dllName 参数。     3、DllImport具有五个命名参数：  a、CallingConvention 参数指示入口点的调用约定。如果未指定 CallingConvention，则使用默认值 CallingConvention.Winapi。b、CharSet 参数指示用在入口点中的字符集。如果未指定 CharSet，则使用默认值 CharSet.Auto。     　　c、EntryPoint 参数给出 dll 中入口点的名称。如果未指定 EntryPoint，则使用方法本身的名称。      　　　d、ExactSpelling 参数指示 EntryPoint 是否必须与指示的入口点的拼写完全匹配。如果未指定 ExactSpelling，则使用默认值 false。      　　　e、PreserveSig 参数指示方法的签名应当被保留还是被转换。当签名被转换时，它被转换为一个具有 HRESULT返回值和该返回值的一个名为 retval 的附加输出参数的签名。如果未指定 PreserveSig，则使用默认值 true。      　　　f、SetLastError 参数指示方法是否保留 Win32"上一错误"。如果未指定 SetLastError，则使用默认值 false。      　4、它是一次性属性类。      　　5、此外，用 DllImport 属性修饰的方法必须具有 extern 修饰符。, DllImport是System.Runtime.InteropServices命名空间下的一个属性类，其功能是提供从非托管DLL导出的函数的必要调用信息, [AttributeUsage(AttributeTargets.Method)], IntPtr LoadLibrary(String path); This has helped a lot.
