WebApr 26, 2016 · The goal is to mimic the functionality of a bit field structure in C with an implementation in C#. This is done by writing some custom attributes that can be applied to the C# struct and also some extension methods used to convert to and from an integer value and also to convert the value to a string with the base-2 representation of the value. WebA bit-field is used to club together many variables into one object, similar to a structure. This allows for reduced memory usage and is especially useful in an embedded environment. e.g. consider the following variables having the ranges as given below. a --> range 0 - 3 b --> range 0 - 1 c --> range 0 - 7 d --> range 0 - 1 e --> range 0 - 1 graff\u0027s turf farms colorado https://thaxtedelectricalservices.com
