error CS0504: The constant 'FieldName.Field1' cannot be marked static.

All constants declarations are implicitly static, and the C# specification states that the (redundant) inclusion of the static modifier is prohibited. I believe this is to avoid the confusion which could occur if a reader were to see two constants, one declared static and one not – they could easily assume that the difference in specification implied a difference in semantics.
