Converting System.Decimal to System.Guid

Question

I have a big dictionary where the key is decimal, but the GetHashCode() of System.Decimal is disasterously bad. To prove my guess, I ran a for loop with 100.000 neigboring d

Convert your decimal value to byte array, and then create a guid from it:

public static byte[] DecimalToByteArray (decimal src) 
{
    using (MemoryStream stream = new MemoryStream()) 
    {
        using (BinaryWriter writer = new BinaryWriter(stream))
        {
            writer.Write(src);
            return stream.ToArray();
        }
    }
}

Decimal myDecimal = 1234.5678M;
Guid guid = new Guid(DecimalToByteArray(myDecimal));
