C#让程序自动以管理员身份运行

C#让程序自动以管理员身份运行

UAC来控制程序访问

?

工具:VS 2008

?

第一步,

????? 新建一个项目(winform)

?

第二步,

????? 在新建项目中,新建项 应用程序清单文件(app.manifest)

?

第三步,

??????打开?app.manifest 文件

????????? 修改 <requestedExecutionLevel level="asInvoker" uiAccess="false" />

????????? 修改为 <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

????????? 重新编译 打开 debug目录 就可以看到图标右下角有个小盾牌的标识。

如下代码:

<?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="requireAdministrator" uiAccess="false" />
      </requestedPrivileges>
    </security>
  </trustInfo>
</asmv1:assembly>

?

第四步,

????? 程序中判断是否以管理员身份运行

代码如下:

/// <summary>
/// 当前是否是管理员身份运行
/// </summary>
/// <returns></returns>
public static bool IsAdministrator()
{
    try
    {
        WindowsIdentity identity = WindowsIdentity.GetCurrent();
        WindowsPrincipal principal = new WindowsPrincipal(identity);
        return principal.IsInRole(WindowsBuiltInRole.Administrator);
    }
    catch
    {
        return true;
    }
}

C# 修改IP地址

        {
            ManagementBaseObject inPar = null;
            ManagementBaseObject outPar = null;
            ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection moc = mc.GetInstances();
            foreach (ManagementObject mo in moc)
            {
                if (!(bool)mo["IPEnabled"])
                    continue;

                //设置ip地址和子网掩码 
                inPar = mo.GetMethodParameters("EnableStatic");
                inPar["IPAddress"] = new string[] { "10.22.21.111", "192.168.1.9" };
                inPar["SubnetMask"] = new string[] { "255.255.255.0", "255.255.255.0" };
                outPar = mo.InvokeMethod("EnableStatic", inPar, null);

                //设置网关地址 
                inPar = mo.GetMethodParameters("SetGateways");
                inPar["DefaultIPGateway"] = new string[] { "10.22.21.1", "192.168.10.1" };
                outPar = mo.InvokeMethod("SetGateways", inPar, null);

                //设置DNS 
                inPar = mo.GetMethodParameters("SetDNSServerSearchOrder");
                inPar["DNSServerSearchOrder"] = new string[] { "179.32.42.4", "179.32.42.5" };
                outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null);
                break;
            }
        }
