Microsoft.Win32.RegistryKey.SetValue() and large values

  • Artículo

On Friday my intern ran into the problem setting a registry DWORD to a large value - a value larger than 2,147,483,647.  The value gets set as a string and not a DWORD even though the DWORD should have UINT's range from 0 to 4,294,967,295.  This is the same problem mentioned by Alexandr Khilov in his article on the The Code Project.  We have a workaround, but I am curious to know if anyone else has run into this.

    I ran into this one and need to develop a fix (I have to be able to write values up to UInt32.MaxValue). What kind of workaround did you use?

    I am looking for a fix for this too. You state a work around, but decline to TYPE IT IN. How bout TYPING IT IN?

    The workaround is to use an UInt32 and then before calling SetValue, cast it to Int32.

    RegistryKey key = Registry.CurrentUser.CreateSubKey("Test");

    RegistryKey subKey = key.CreateSubKey("SubKey");
    System.UInt32 ui = 3147483657;
    subKey.SetValue("It's a DWORD", (Int32)ui);


    Here's the KB article about this:

    Hope this helps.
