I bet there is an article out there somewhere that tells you exactly what .NET Types to use with the corresponding SQL column types but I couldn’t find it anywhere. After scanning for a few minutes I decided to just write something up that tells me definitively what Type to use.
In this case I needed it because I had a bug in NBusiness whith the mapping to the double. After changing the Type a few times I couldn’t figure out what Type to actually map to a double. So I created a table that has one column of each type and I used a simple SqlDataReader to figure out the .NET Type of the field.
I created a simple type mapper just to show me what I wanted. And here are the results:
|Sql Type||.NET Type|
