public class ComputerInfo

The ComputerInfo type exposes the following members.

Public methodComputerInfoInitializes a new instance of the ComputerInfo class.

Public propertyAvailablePhysicalMemoryGets the total amount of free physical memory for the computer.
Public propertyAvailableVirtualMemoryGets the total amount of the computer's free virtual address space.
Public propertyInstalledUICultureGets the current UI culture installed with the operating system.
Public propertyOSFullNameGets the full operating system name.
Public propertyOSPlatformGets the platform identifier for the operating system of the computer.
Public propertyOSVersionGets the version of the computer's operating system.
Public propertyTotalPhysicalMemoryGets the total amount of physical memory for the computer.
Public propertyTotalVirtualMemoryGets the total amount of virtual address space available for the computer.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The properties exposed by the My.Computer.Info object return information about the computer from which the application is deployed, as determined at run time. Typically, this data differs from what was available on the development computer.


The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: Resources. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

This example uses the My.Computer.Info.AvailablePhysicalMemory property to display the amount of available physical memory for the computer on which the code runs.
