WMI and Win32_NetworkAdapterConfiguration - System.InvalidCastException: Cast from string to Date

[Mark Hollander]

Hi,

I am using the WMI management object to obtain values about the network
cards installed on the system.

The MSDN tells me the following
class Win32_NetworkAdapterConfiguration : CIM_Setting
{
...
datetime DHCPLeaseExpires;
datetime DHCPLeaseObtained;
...
};


When I use the following code

Dim dExpires as DateTime
dExpires = CType(wmi.Item("DHCPLeaseExpires"), DateTime)

I Get the following exception

System.InvalidCastException: Cast from string
"20041109122048.000000+120" to type 'Date' is not valid.

at Assimilator.SDK.clsNICProperties.PopulateNetworkAdapterArray() in
V:\VBNET\Assimilator Ver 4.2\Assimilator.SDK\clsNICProperties.vb:line

How do I fix ?????



Thank You

Dim dExpires as DateTime
dExpires = CType(wmi.Item("DHCPLeaseExpires"), DateTime)

I Get the following exception

System.InvalidCastException: Cast from string

Take a look at the 'System.Management.ManagementDateTimeConverter' class.
