سلام دوست عزیز
شما باید از متدهای SetValue و GetValue مربوط به کلاس Microsoft.Win32.Registry استفاده نمایید :
مثالی از MSDN :

using System;

using Microsoft.Win32;

public class Example

{

    public static void Main()

    {

        // The name of the key must include a valid root.

        const string userRoot = "HKEY_CURRENT_USER";

        const string subkey = "RegistrySetValueExample";

        const string keyName = userRoot + "\\" + subkey;

        // An int value can be stored without specifying the

        // registry data type, but long values will be stored

        // as strings unless you specify the type. Note that

        // the int is stored in the default name/value

        // pair.

        Registry.SetValue(keyName, "", 5280);

        Registry.SetValue(keyName, "TestLong", 12345678901234,

            RegistryValueKind.QWord);

        // Strings with expandable environment variables are

        // stored as ordinary strings unless you specify the

        // data type.

        Registry.SetValue(keyName, "TestExpand", "My path: %path%");

        Registry.SetValue(keyName, "TestExpand2", "My path: %path%",

            RegistryValueKind.ExpandString);

        // Arrays of strings are stored automatically as 

        // MultiString. Similarly, arrays of Byte are stored

        // automatically as Binary.

        string[] strings = {"One", "Two", "Three"};

        Registry.SetValue(keyName, "TestArray", strings);

        // Your default value is returned if the name/value pair

        // does not exist.

        string noSuch = (string) Registry.GetValue(keyName, 

            "NoSuchName",

            "Return this default if NoSuchName does not exist.");

        Console.WriteLine("\r\nNoSuchName: {0}", noSuch);

        // Retrieve the int and long values, specifying 

        // numeric default values in case the name/value pairs

        // do not exist. The int value is retrieved from the

        // default (nameless) name/value pair for the key.

        int tInteger = (int) Registry.GetValue(keyName, "", -1);

        Console.WriteLine("(Default): {0}", tInteger);

        long tLong = (long) Registry.GetValue(keyName, "TestLong",

            long.MinValue);

        Console.WriteLine("TestLong: {0}", tLong);

        // When retrieving a MultiString value, you can specify

        // an array for the default return value. 

        string[] tArray = (string[]) Registry.GetValue(keyName,

            "TestArray",

            new string[] {"Default if TestArray does not exist."});

        for(int i=0; i<tArray.Length; i++)

        {

            Console.WriteLine("TestArray({0}): {1}", i, tArray[i]);

        }

        // A string with embedded environment variables is not

        // expanded if it was stored as an ordinary string.

        string tExpand = (string) Registry.GetValue(keyName,

             "TestExpand", 

             "Default if TestExpand does not exist.");

        Console.WriteLine("TestExpand: {0}", tExpand);

        // A string stored as ExpandString is expanded.

        string tExpand2 = (string) Registry.GetValue(keyName,

            "TestExpand2",

            "Default if TestExpand2 does not exist.");

        Console.WriteLine("TestExpand2: {0}...",

            tExpand2.Substring(0, 40));

        Console.WriteLine("\r\nUse the registry editor to examine the key.");

        Console.WriteLine("Press the Enter key to delete the key.");

        Console.ReadLine();

        Registry.CurrentUser.DeleteSubKey(subkey);

    }

}

//

// This code example produces output similar to the following:

//

//NoSuchName: Return this default if NoSuchName does not exist.

//(Default): 5280

//TestLong: 12345678901234

//TestArray(0): One

//TestArray(1): Two

//TestArray(2): Three

//TestExpand: My path: %path%

//TestExpand2: My path: D:\Program Files\Microsoft.NET\...

//

//Use the registry editor to examine the key.

//Press the Enter key to delete the key.
