Registry.CurrentUser Field

Contains information about the current user preferences. This field reads the Windows registry base key HKEY_CURRENT_USER

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

public static readonly RegistryKey CurrentUser
public static final RegistryKey CurrentUser
public static final var CurrentUser : RegistryKey

Information stored in this key includes the settings of environment variables and data about program groups, colors, printers, network connections, and application preferences. This key makes it easier to establish the current user's settings. In this key, software vendors store the current user-specific preferences to be used within their applications. Microsoft, for example, creates the HKEY_CURRENT_USER\Software\Microsoft key for its applications to use, with each application creating its own subkey under the Microsoft key.

The following example demonstrates how to retrieve the subkeys of this key, and prints their names to the screen. Use the OpenSubKey method to create an instance of the particular subkey of interest. You can then use other operations in RegistryKey to manipulate that key.

using System;
using Microsoft.Win32;

class Reg {
    public static void Main() {

        // Create a RegistryKey, which will access the HKEY_CURRENT_USER
        // key in the registry of this machine.
        RegistryKey rk = Registry.CurrentUser;

        // Print out the keys.
        PrintKeys(rk);
    }

    static void PrintKeys(RegistryKey rkey) {

        // Retrieve all the subkeys for the specified key.
        String [] names = rkey.GetSubKeyNames();

        int icount = 0;

        Console.WriteLine("Subkeys of " + rkey.Name);
        Console.WriteLine("-----------------------------------------------");

        // Print the contents of the array to the console.
        foreach (String s in names) {
            Console.WriteLine(s);

            // The following code puts a limit on the number
            // of keys displayed.  Comment it out to print the
            // complete list.
            icount++;
            if (icount >= 10)
                break;
        }
    }
}
