Saving the TextBox Values in Registry

Question

I need some guidance in reading/writing/saving the values in Registry.I am new to this concept of saving things in registry

I have a Winform where i have to read/write to a App.config file and change the username and password using a winform.In my winform i have 2 textboxes and when i enter values and hit submit it changes the values in app.config.I somehow did that and no issues.

Now I need to send what ever values I have entered in the Textboxes to registry and save them thr and I should also be able to read them.

How shoud I do that ?

Answer 1

Here is a quick code:

private void button1_Click(object sender, EventArgs e)
{
    Microsoft.Win32.RegistryKey exampleRegistryKey = Microsoft.Win32.Registry.CurrentUser.CreateSubKey("ExampleTest");
    exampleRegistryKey.SetValue("Name", textBox1.Text);
    exampleRegistryKey.Close();
}

Now if you run regedit and must see under HKEY_CURRENT_USER\ExampleTest

Miscall

Answer 2

using Microsoft.Win32;

To write:

Registry.SetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\MyProgram", "Username", "User1");

To read:

string username = Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\MyProgram",
                                    "Username", "NULL").ToString();

In read where I have put NULL - thats the value to return if the value you are looking for isn't there.

So if you did:

if(username == "NULL")
{
    // it doesn't exist, handle situation here
}

Hope this helps.

Yes Buddy.Thank you.... Do you have any Example to display here about this registry read/write/save ?? – Felisafelise

@Felisafelise No probs. Updated question with actual data. If you had a key named MyProgram and you set the value Username with the first code and you get the value using the second. Once you make the change you don't need to save it. – Karolinekaroly

@Felisafelise No problem, if this answers your question you should accept it, just click the tick :D – Karolinekaroly

Just to note: The route may translate to: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MyProgram. – Bothwell
