坚果云是我常用的一个工具，但是我一般喜欢使用绿色版，不喜欢程序到处写文件，也不喜欢重装以后还要各种登录。所以要折腾“绿色版”来使用。坚果云的完整版下载链接为 https://pkg-cdn.jianguoyun.com/static/exe/installer/NutstoreWindowsWPF_Full.exe 手动IL处理 一般手动处理坚果云的个人用户资料目录。需要使用dnspyEx，然后修改NutstoreLib.dll中的Utils.DirectoryUtils下的APPDATA_NUTSTORE_DIR,下面是我的一个手动IL修改列表： 0 0000 call string NutstoreLib.Utils.DirectoryUtils::get_NUTSTORE_INSTALL_DIR() 1 0005 newobj instance void [mscorlib]System.IO.DirectoryInfo::.ctor(string) 2 000A call instance class [mscorlib]System.IO.DirectoryInfo [mscorlib]System.IO.DirectoryInfo::get_Parent() 3 000F callvirt instance string [mscorlib]System.IO.FileSystemInfo::get_FullName() 4 0014 ldstr "UserData" 5 0019 call string [Pri.LongPath]Pri.LongPath.Path::Combine(string, string) 6 001E ret 自动IL处理 借助Mono.Cecil我们可以实现上面的功能，自动进行dll的patch修改。 注：因为我不喜欢调用太多的库，所以Pri.LongPath.Path::Combine(string, string)我改为了系统的库 完整代码如下： using System.Linq; using Mono.Cecil; using Mono.Cecil.Cil; namespace NutstoreAutoPatch { internal class Program { public static void Main(string[] args) { const string nutstoreLib = "NutstoreLib.dll"; const string directoryutils = "NutstoreLib.Utils.DirectoryUtils"; const string appdataNutstoreDir = "get_APPDATA_NUTSTORE_DIR"; // Read the assembly var assemblyDefinition = AssemblyDefinition.ReadAssembly(nutstoreLib); var directoryUtil = assemblyDefinition.MainModule.Types.First(t => t.FullName == directoryutils); var appdataDirMethod = directoryUtil.Methods.First(m => m.Name == appdataNutstoreDir); // 清除当前指令 appdataDirMethod.Body.Instructions.Clear(); // 获取IL处理器 var ilProcessor = appdataDirMethod.Body.GetILProcessor(); // 构造调用NutstoreLib.Utils.DirectoryUtils.get_NUTSTORE_INSTALL_DIR的指令 var getInstallDirMethod = appdataDirMethod.Module.ImportReference( appdataDirMethod.DeclaringType.Module.Types .First(t => t.Name == "DirectoryUtils" && t.Namespace == "NutstoreLib.Utils") .Methods.First(m => m.Name == "get_NUTSTORE_INSTALL_DIR") ); ilProcessor.Append(ilProcessor.Create(OpCodes.Call, getInstallDirMethod)); // 构造调用System.IO.DirectoryInfo构造函数的指令 var directoryInfoConstructor = appdataDirMethod.Module.ImportReference( typeof(System.IO.DirectoryInfo).GetConstructor(new[] { typeof(string) }) ); ilProcessor.Append(ilProcessor.Create(OpCodes.Newobj, directoryInfoConstructor)); // 构造获取DirectoryInfo.Parent属性的调用指令 var getParentMethod = appdataDirMethod.Module.ImportReference( typeof(System.IO.DirectoryInfo).GetProperty("Parent").GetGetMethod() ); ilProcessor.Append(ilProcessor.Create(OpCodes.Call, getParentMethod)); // 构造调用System.IO.FileSystemInfo.FullName属性的指令 var getFullNameMethod = appdataDirMethod.Module.ImportReference( typeof(System.IO.FileSystemInfo).GetProperty("FullName").GetGetMethod() ); ilProcessor.Append(ilProcessor.Create(OpCodes.Callvirt, getFullNameMethod)); // 加载字符串"UserData" ilProcessor.Append(ilProcessor.Create(OpCodes.Ldstr, "UserData")); // 构造调用Pri.LongPath.Path.Combine的指令 var pathCombineMethod = appdataDirMethod.Module.ImportReference( typeof(System.IO.Path).GetMethod("Combine", new[] { typeof(string), typeof(string) }) ); ilProcessor.Append(ilProcessor.Create(OpCodes.Call, pathCombineMethod)); // 返回指令 ilProcessor.Append(ilProcessor.Create(OpCodes.Ret)); // Write the modified assembly assemblyDefinition.Write("NutstoreLib_patched.dll"); } } } 程序编译后，将最新的NutstoreLib.dll拷贝进来，执行下，再使用NutstoreLib_patched.dll替换原来安装目录的NutstoreLib.dll即可。
