Mapping and Installing Host Instances Using WMI

 

Use the following code to map and install host instances using the MSBTS_ServerHost and MSBTS_HostInstance classes.

using System.Management;  
  
//Function to Map and Install a HostInstance using MSBTS_ServerHost and MSBTS_HostInstance  
      public void MapAndInstall(string hostName, string svrName, string uid, string pwd)  
      {  
         try

            //Build the name of the HostInstance - name has to be in the below format  
            string hostInstanceName = "Microsoft BizTalk Server" //Name of product  
                              + " " + hostName         //Name of Host of which instance is to be created  
                              + " " + svrName;         //Name of Server on which instance is to be created  
  
            //Create an instance of the ServerHost class using the System.Management namespace  
            ObjectGetOptions svrHostOptions = new ObjectGetOptions();  
            ManagementClass svrHostClass = new ManagementClass("root\\MicrosoftBizTalkServer","MSBTS_ServerHost",svrHostOptions);  
            ManagementObject svrHostObject = svrHostClass.CreateInstance();  
  
            //Set the properties of the ServerHost instance  
            svrHostObject["ServerName"] = svrName;

            hostInstObject.InvokeMethod("Install",args);  
  
            Console.WriteLine("HostInstance was mapped and installed successfully. Mapping created between Host: " + hostName + " and Server: " + svrName);  
                         return;
