如何使用WMI通过C从64位计算机(WOW)上以32位模式运行的应用程序访问64位注册表配置单元信息?#

我认为这个问题真的总结了我想做的事情。这是我使用的代码。除了我的应用程序在64位机器上以32位模式运行之外,它在每个场景中都能工作。无论我如何使用“providerarchitecture”和“requiredarchitecture”标志进行播放,我始终只能访问配置单元的32位部分(wow6432节点)。

uint LOCAL_MACHINE = 0x80000002;
string results = "";
ConnectionOptions options = new ConnectionOptions();
options.Impersonation = ImpersonationLevel.Impersonate;
options.EnablePrivileges = true;
options.Username = this.txtUser.Text;
options.Password = this.txtPassword.Text;

ManagementScope myScope = new ManagementScope("\\\\" + this.txtMachine.Text + "\\root\\default", options);
ManagementPath mypath = new ManagementPath("StdRegProv");
ManagementClass mc = new ManagementClass(myScope, mypath, null);

ManagementBaseObject inParams = mc.GetMethodParameters("EnumKey");
inParams["hDefKey"] = LOCAL_MACHINE;
inParams["sSubKeyName"] = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";

ManagementNamedValueCollection objCtx = new ManagementNamedValueCollection();
objCtx.Add("__ProviderArchitecture", 64);
objCtx.Add("__RequiredArchitecture", true);


InvokeMethodOptions invokeOptions = new InvokeMethodOptions();
invokeOptions.Context = objCtx;
ManagementBaseObject outParams = mc.InvokeMethod("EnumKey", inParams, invokeOptions);

inParams = mc.GetMethodParameters("GetStringValue");
inParams["hDefKey"] = LOCAL_MACHINE;

foreach(string name in (string[])outParams["sNames"])
{
      inParams["sSubKeyName"] = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" + "\\" + name;
      inParams["sValueName"] = "DisplayName";
      outParams = mc.InvokeMethod("GetStringValue", inParams, invokeOptions);

      if (!string.IsNullOrEmpty(((string)outParams["sValue"])))
      {
          results += outParams["sValue"] + "\t";
      }
 }
