The information in this article applies to:

SYMPTOMS

When you use the System.Management.ObjectGetOptions enumeration in the ManagementClass class constructor in Microsoft Visual C# .NET and in Microsoft Visual C# 2005, you may receive the following compiler error message:

Argument '3': cannot convert from 'System.TimeSpan' to 'System.Management.ObjectGetOptions'

CAUSE

This issue occurs if the ManagementClass class constructor is passed to the System.Management.ObjectGetOptions.InfiniteTimeout field as a third parameter. The following code is an example:

ManagementClass objClass = new  ManagementClass("","",System.Management.ObjectGetOptions.INFINITE);

RESOLUTION

The ManagementClass class constructor is used as follows:

If you want an uninitialized ManagementClass object, use the default class contractor as follows:

ManagementClass objClass = new ManagementClass();
