Eziriz.Net.Reactor使用注意事项

1) 保护参数配置

2) 注册表访问

using System.Security.Permissions;[RegistryPermissionAttribute(SecurityAction.PermitOnly, All = @"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\Engines\Jet 4.0")]
private static void UpdateOS32RegisterItem()
{
 using (RegistryKey currentKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Jet\4.0\Engines\Jet 4.0", true))
{
currentKey.SetValue("MaxLocksPerFile", 0xF4240, RegistryValueKind.DWord);
currentKey.Close();
}
}

该种写法混淆后会出现如下的错误:

解决方法:

添加 应用程序清单文件，在其中加入

<?xml version="1.0" encoding="utf-8"?>
<asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <assemblyIdentity version="1.0.0.0" name="MyApplication.app"/>
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
    <security>
      <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
        <!-- UAC 清单选项
            如果希望更改 Windows 用户帐户控制级别，请用以下节点之一替换
            requestedExecutionLevel 节点。        <requestedExecutionLevel  level="asInvoker" uiAccess="false" />
        <requestedExecutionLevel  level="requireAdministrator" uiAccess="false" />
        <requestedExecutionLevel  level="highestAvailable" uiAccess="false" />            如果您希望利用文件和注册表虚拟化提供
            向后兼容性，请删除 requestedExecutionLevel 节点。
        -->
        <requestedExecutionLevel level="asInvoker" uiAccess="false" />
        <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
      </requestedPrivileges>
    </security>
  </trustInfo>
</asmv1:assembly>

修改代码，如下：

private static void UpdateOS32RegisterItem()
 {
System.Security.Principal.WindowsIdentity identity = System.Security.Principal.WindowsIdentity.GetCurrent();
System.Security.Principal.WindowsPrincipal principal = new System.Security.Principal.WindowsPrincipal( identity );
if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.Administrator))
{
using (RegistryKey currentKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Jet\4.0\Engines\Jet 4.0", true))
{
currentKey.SetValue("MaxLocksPerFile", 0xF4240, RegistryValueKind.DWord);
currentKey.Close();
}
}
 }
