Wondering if they removed DataType in 4.5 ? This would be most unfortunate - how can I get both .NET type and SqlDbType then using SchemaOnly?

>>       public Int16 Precision { get; set; }
>>       public Int16 Scale { get; set; }
>>    }

>>                        String readerColumnName = r["ColumnName"].ToString();
>>                        colSchema.ColumnName = readerColumnName;
>>                        colSchema.ColumnSize = r.Field<Int16>("ColumnSize");
>>                        colSchema.DataType = (Type)(r["DataType"].ToString());

>>The last line is failing, of course.

>>I am not sure how to get that DataType property to be the Type type. In the code above when I output all info, that was fine, as I output everything as a string. But how do I know the actual type of returned property and how can I set it for my new ColumnSchema properties?
