41.  static readonly field is set at run time, and can thus be modified by the containing class  the value of a const field is set to a compile time constant.  In the static readonly case, the containing class is allowed to modify it only in the variable declaration (through a variable initializer) in the static constructor (instance constructors, if it's not static)  static readonly is typically used if the type of the field is not allowed in a const declaration, or when the value is not known at compile time.  Instance readonly fields are also allowed.  Remember that for reference types, in both cases (static and instance) the readonly modifier only prevents you from assigning a new reference to the field. It specifically does not make immutable the object pointed to by the reference. 41
