Hi,

I am using vSphere 5.5  SDK to retrieve hosts and vm's data from VMware ESXi 4. The application successfully fetches data for hosts but it fails with the below exception when I try to retrieve data for datastores or vm's

at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)

   at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)

   at Vim25Api.VimService.RetrieveServiceContent(ManagedObjectReference _this)

It fails (at highlighted red line) when I try to use below get properties method. Any help to resolve this would be greatly appreciated.

public static Object[] getProperties(ManagedObjectReference moRef, String[] properties) {

              // PropertySpec specifies what properties to retrieve and from type of Managed Object

              PropertySpec pSpec = new PropertySpec();

              pSpec.type = moRef.type;

              pSpec.pathSet = properties;

              // ObjectSpec specifies the starting object and any TraversalSpecs used to specify other objects for consideration

              ObjectSpec oSpec = new ObjectSpec();

              oSpec.obj = moRef;

             // PropertyFilterSpec is used to hold the ObjectSpec and PropertySpec for the call

              PropertyFilterSpec pfSpec = new PropertyFilterSpec();

              pfSpec.propSet = new PropertySpec[] { pSpec };

              pfSpec.objectSet = new ObjectSpec[] { oSpec };

             // retrieveProperties() return the properties selected from PropertyFilterSpec

              ManagedObjectReference _svcRef1 = new ManagedObjectReference();

              _svcRef1.type = "Service Instance";

              _svcRef1.Value = "Service Instance";

              ServiceContent sic1 = null;

              vim_svc.Timeout = 600000; //The value can be set to some higher value also.

             sic1  = vim_svc.RetrieveServiceContent(_svcRef1);

              ObjectContent[] ocs = new ObjectContent[20];

              ocs = vim_svc.RetrieveProperties(sic1.propertyCollector, new PropertyFilterSpec[] { pfSpec });

              // Return value, one object for each property specified

              Object[] ret = new Object[properties.Length];

              if (ocs != null) {

                  for (int i = 0; i < ocs.Length; i++) {

                      ObjectContent oc = ocs[i];

                      DynamicProperty[] dps = oc.propSet;

                      if (dps != null) {

                          for (int j = 0; j < dps.Length; ++j) {

                              DynamicProperty dp = dps[j];

                              //Find property path index

                              for (int p = 0; p < ret.Length; ++p) {

                                  if (properties[p].Equals(dp.name)) {

                                      ret[p] = dp.val;

                                  }

                              }

                          }

                      }

                  }      

              }

              return ret;   

          }
