是否可以在C＃程序中将传输代理安装到Exchange Server？
通常您创建Agent .dll，然后需要打开Exchange命令行管理程序并执行以下命令：
Install-TransportAgent -Name "Agent Name" -TransportAgentFactory "Factory.Class.Name" -AssemblyPath "C:\Path\to\agent.dll"
和
enable-transportagent -Identity "Agent Name"
并设置优先级：
Set-TransportAgent -Identity "Agent Name" -Priority 3
如何在C＃应用程序中安装传输代理（调用PowerShell命令或直接使用.NET Framework？
答案 0 :(得分：2)
我找到了一个直接从C＃使用PowerShell并调用相应cmdlet的解决方案：

是的，可以使用C＃安装\卸载Exchange传输代理。事实上，我已经做到了。
我所做的是，我使用PowerShell调用了Exchange cmdlet，并在Exchange中心服务器上安装了代理。我还必须停止\使用C＃启动MS Exchange传输代理服务。此外，我还必须创建文件夹，我必须放置代理文件，并授予该文件夹的网络服务读/写权限。

我编写了一个类，允许您在本地或通过远程shell运行exchange命令。
此课程提供以下命令：
GetAgentInfo : Receive the transport agent information by passing the NAme as parameter
InstallAgent : Install a transport agent by passing Name, FactoryNAme and Assembly path
EnableAgent : Enable a transport agent
UninstallAgent : Uninstall a transportagent
RestartTransportService : Restart the Microsoft Transport Service
它还会验证安装了哪个版本的Exchange以加载正确的SnapIn

用法：
// Local
ExchangeShell shell = new ExchangeShell();
var localAgentInfo = shell.GetAgentInfo("YourAgentName");
// continue with a remote call
shell.SetRemoteHost("anotherexchangeserver.your.domain");
var remoteAgentInfo = shell.GetAgentInfo("YourAgentName");
// close all connections
shell.Dispose();
