Object is NULL if querying a VM with brackets in DisplayName

Hello everybody,

I just started using the VimClient with C#/.NET

I have the following code:

	VimClient client = new VimClient();
	client.Connect(serviceUrl);
	client.Login(userName, password);
	NameValueCollection filter = new NameValueCollection();

 

	int countCheckedVMs = clbVMsToolsNeedUpgrade.CheckedItems.Count - 1;
	for (int i = 0; i <= countCheckedVMs; i++ )
	{
	string displayName = clbVMsToolsNeedUpgrade.CheckedItems[i].ToString();

 

	filter.Add("Config.Name", displayName);
	MessageBox.Show(filter[0].ToString());
	IList<EntityViewBase> vmList = client.FindEntityViews(typeof(VirtualMachine), null, filter, null);
	foreach (VirtualMachine vm in vmList)
	{
	vm.UpgradeTools("/S /v\"/qn REBOOT=ReallySuppress\"");
	rtbLog.AppendText("VMware Tools-Upgrade for VM " + displayName + " started\n");
	}

 

	filter.Remove("Config.Name");
	}

 

client.Disconnect();

This is working good until it comes to a VM which has brackets in its displayname.

So a VM called "My Server" is working but not "My Server (rellay)"

I have no idea why, cant the VimClient handle the brackets?
