You can try the function below to read values from the Registry:



  • input: the key name (string)
  • output: the value of the key (string)
using System;
using Microsoft.Win32;  
public string Read(string KeyName)
    // Opening the registry key
      RegistryKey rk = baseRegistryKey ;
    // Open a subKey as read-only

    RegistryKey sk1 = rk.OpenSubKey(subKey);
    // If the RegistrySubKey doesn't exist -> (null)

    if ( sk1 == null )
        return null;
       // If the RegistryKey exists I get its value or null is returned.        
         return (string)sk1.GetValue(KeyName.ToUpper());
        catch (Exception e)
            ShowErrorMessage(e, "Reading registry " + KeyName.ToUpper());
            return null;

Note: if MY_KEY doesn't exist, the Read function will return null.
