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;
}
}
?

其他:
C# 修改IP地址
static void SetNetworkAdapter()
{
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;
}
}
