RegistryKey.GetValueNames Method ()


Retrieves an array of strings that contains all the value names associated with this key.

Namespace:   Microsoft.Win32
Assembly:  mscorlib (in mscorlib.dll)

public string[] GetValueNames()

Return Value

Type: System.String[]

An array of strings that contains the value names for the current key.

Exception Condition

The user does not have the permissions required to read from the registry key.


The RegistryKey being manipulated is closed (closed keys cannot be accessed).


The user does not have the necessary registry rights.


A system error occurred; for example, the current key has been deleted.

If no value names for the key are found, an empty array is returned.

A registry key can have a default value — that is, a name/value pair in which the name is the empty string (""). If a default value has been set for a registry key, the array returned by the GetValueNames method includes the empty string.

This code example is part of a larger example provided for the RegistryKey class.

// Print the information from the Test9999 subkey.
Console.WriteLine("There are {0} subkeys under {1}.", 
    test9999.SubKeyCount.ToString(), test9999.Name);
foreach(string subKeyName in test9999.GetSubKeyNames())
        tempKey = test9999.OpenSubKey(subKeyName))
        Console.WriteLine("\nThere are {0} values for {1}.", 
            tempKey.ValueCount.ToString(), tempKey.Name);
        foreach(string valueName in tempKey.GetValueNames())
            Console.WriteLine("{0,-8}: {1}", valueName,
