如果我不知道它的类型，如何从远程计算机获取注册表值？ （C＃）
根据存储的值类型，我必须使用以下方法之一：
GetBinaryValue GetDWORDValue GetExpandedStringValue GetMultiStringValue GetStringValue 如果我所知道的值是hive，key和value name，我不想尝试所有五个。 有没有办法做到这一点？ 我正在使用WMI，但如果唯一的方法是使用advapi32.dll方法，我对此持开放态度。
您可以使用StdRegProv.EnumValues方法枚举键的值，找出值的类型并确定要调用的Get方法。
这样的事情（抱歉，我不太了解C＃所以这段代码可能远非完美）：
using System; using System.Management; using System.Management.Instrumentation; namespace ConsoleApplication1 { public enum RegHive : uint { HKEY_CLASSES_ROOT = 0x80000000, HKEY_CURRENT_USER = 0x80000001, HKEY_LOCAL_MACHINE = 0x80000002, HKEY_USERS = 0x80000003, HKEY_CURRENT_CONFIG = 0x80000005 } public enum RegType { REG_SZ = 1, REG_EXPAND_SZ, REG_BINARY, REG_DWORD, REG_MULTI_SZ = 7 } class Program { static void Main(string[] args) { const string strComputer = "computername"; ConnectionOptions options = new ConnectionOptions(); options.Impersonation = ImpersonationLevel.Impersonate; options.EnablePrivileges = true; options.Username = "username"; options.Password = "password"; ManagementScope myScope = new ManagementScope("\\\\" + strComputer + "\\root\\default", options); ManagementPath mypath = new ManagementPath("StdRegProv"); ManagementClass mc = new ManagementClass(myScope, mypath, null); object oValue = GetValue(mc, RegHive.HKEY_LOCAL_MACHINE, "SOFTWARE\\Microsoft\\Windows\\CurrentVersion", "ProgramFilesDir"); Console.WriteLine(oValue.ToString()); } public static object GetValue(ManagementClass mc, RegHive hDefKey, string sSubKeyName, string sValueName) { RegType rType = GetValueType(mc, hDefKey, sSubKeyName, sValueName); ManagementBaseObject inParams = mc.GetMethodParameters("GetStringValue"); inParams["hDefKey"] = hDefKey; inParams["sSubKeyName"] = sSubKeyName; inParams["sValueName"] = sValueName; object oValue = null; switch (rType) { case RegType.REG_SZ: ManagementBaseObject outParams = mc.InvokeMethod("GetStringValue", inParams, null); if (Convert.ToUInt32(outParams["ReturnValue"]) == 0) { oValue = outParams["sValue"]; } else { // GetStringValue call failed } break; case RegType.REG_EXPAND_SZ: outParams = mc.InvokeMethod("GetExpandedStringValue", inParams, null); if (Convert.ToUInt32(outParams["ReturnValue"]) == 0) { oValue = outParams["sValue"]; } else { // GetExpandedStringValue call failed } break; case RegType.REG_MULTI_SZ: outParams = mc.InvokeMethod("GetMultiStringValue", inParams, null); if (Convert.ToUInt32(outParams["ReturnValue"]) == 0) { oValue = outParams["sValue"]; } else { // GetMultiStringValue call failed } break; case RegType.REG_DWORD: outParams = mc.InvokeMethod("GetDWORDValue", inParams, null); if (Convert.ToUInt32(outParams["ReturnValue"]) == 0) { oValue = outParams["uValue"]; } else { // GetDWORDValue call failed } break; case RegType.REG_BINARY: outParams = mc.InvokeMethod("GetBinaryValue", inParams, null); if (Convert.ToUInt32(outParams["ReturnValue"]) == 0) { oValue = outParams["uValue"] as byte[]; } else { // GetBinaryValue call failed } break; } return oValue; } public static RegType GetValueType(ManagementClass mc, RegHive hDefKey, string sSubKeyName, string sValueName) { ManagementBaseObject inParams = mc.GetMethodParameters("EnumValues"); inParams["hDefKey"] = hDefKey; inParams["sSubKeyName"] = sSubKeyName; ManagementBaseObject outParams = mc.InvokeMethod("EnumValues", inParams, null); if (Convert.ToUInt32(outParams["ReturnValue"]) == 0) { string[] sNames = outParams["sNames"] as String[]; int[] iTypes = outParams["Types"] as int[]; for (int i = 0; i < sNames.Length; i++) { if (sNames[i] == sValueName) { return (RegType)iTypes[i]; } } // value not found } else { // EnumValues call failed } } } }
OpenRemoteBaseKey，GetValue（）怎么样？ http://msdn.microsoft.com/en-us/library/8zha3xws(VS.100).aspx
