Read Registry key and write in textbox the value

I have found the following code which reads and writes from the registry.

// Write a value to the registry
Microsoft.Win32.RegistryKey key;
key = Microsoft.Win32.Registry.CurrentUser.CreateSubKey("Names");
key.SetValue("Name","Isabella");

// Get value from registry
key.GetValue("Name");    
textBox1.Text = key.GetValue("Name"); // error, how can I do?

key.Close()开发者_如何学编程;

How would I display the value in a TextBox?

Add a call ToString() after ensuring the value isn't null.

object oVal = key.GetValue("Name");
if (null != oVal) 
{
   textBox1.Text = oVal.ToString();
}

try

textBox1.Text = key.GetValue("Name").ToString();

GetValue returns an object and textbox1.Text wants a string so you need to convert first.
