In object-oriented programming, classes can contain attributes and methods. An attribute in a relational database can be represented as a column or field. In computing, an attribute is a specification that defines a property of an object, element, or file. It may also refer to or set the specific value for a given instance of
Push the value of field of object (or value type) obj, onto the stack. Object model instruction 0x7C ldflda <field> Push the address of field of object obj on the stack. Object model instruction 0xFE 0x06 ldftn <method> Push a pointer to a method referenced by method, on the stack. Base instruction 0x4D ldind.i
When copied into objects, the official release boxes values from Nullable instances, so null values and null references are considered equal. The late nature of this fix caused some controversy [5], since it required core-CLR changes affecting not only .NET2, but all dependent technologies (including C#, VB, SQL Server 2005 and Visual Studio 2005).
