Here is my code:

// Find the virtual machine list from the virtual machine folder found above.

ManagedObjectReference] vmList = (ManagedObjectReference[)getObjectProperty(vmFolderRef, "childEntity");

//Searching for the template/virtual machine

ManagedObjectReference templateRef = null;

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

{

if (vmList.type == "VirtualMachine")

{

Object[] vmProps = getProperties(vmListi], new String[ { "config.name", "config.template" });

if (((String)vmProps[0]).Equals(srcName))

{

templateRef = vmList;

}

}

}

// Define the operation to be performed.

MethodAction ma = new MethodAction();

ma.argument = new MethodActionArgument[1];

ma.name = "PowerOffVM_Task";

DateTime theDate = DateTime.Now;

theDate.AddMinutes(1);

// Define the scheduled task specification.

OnceTaskScheduler dTScheduler = new OnceTaskScheduler();

dTScheduler.runAt = theDate;

dTScheduler.runAtSpecified = true;

dTScheduler.activeTimeSpecified = true;

dTScheduler.activeTime = DateTime.Now;

dTScheduler.expireTime = theDate.AddHours(1);

dTScheduler.expireTimeSpecified = true;

ScheduledTaskSpec tSpec = new ScheduledTaskSpec();

tSpec.description = "Revert to the specified snapshot according to the schedule.";

tSpec.enabled = true;

tSpec.name = "Power Off Virtual Machine";

tSpec.action = ma;

tSpec.scheduler = dTScheduler;

tSpec.notification = Foo@Bar.com;

VS.CreateScheduledTask(_ServiceContent.scheduledTaskManager, templateRef, tSpec);

Error: SOAPEXCEPTION was unhandled. Aspecified parameter was not correct.

Do i am doing wrong with this parameter:--------------------------------------------

ma.argument = new MethodActionArgument[1];
