How do I create an ODBC DSN entry using C#?

Question

I\'m working on a legacy application that has a C++ extended stored procedure. This xsproc uses ODBC to connect to the database, which means it requires a DSN to be config

+1 for Barnwell's code!

However, I think his DSNExists() is querying the wrong key. I think it should be this:

public static bool DSNExists(string dsnName) 
{ 
    var sourcesKey = Registry.LocalMachine.CreateSubKey(ODBC_INI_REG_PATH + "ODBC Data Sources"); 
    if (sourcesKey == null) throw new Exception("ODBC Registry key for sources does not exist"); 

    return sourcesKey.GetValue(dsnName) != null; 
}
