That Registry value is type REG_EXPAND_SZ and those numbers are the Unicode values of the characters in that string. Notice this part near the end:

2d,00,39,00,39,00,39,00,31,00

That corresponds to the -9991 at the end of the value in the Registry. The Unicode values for the characters '-', '9' and '1' are 2D, 39 and 31 respectively.

So, if you have data in that form, you need to convert the numeric values to text and then call RegistryKey.SetValue and specify the RegistryValueKind as ExpandString.

An easier way might to simply execute a REG file containing that data, so Windows can handle the import for you.
