问题
Is it possible to have some code let the compiler generate a compile warning or error?
Maybe with Attributes?

Having the first answer and a few comments I realize my question is not as a clear as I expected and wanted it to be. I apologize. Hopefully all contributers are still with us.

So I am more looking towards an internal DSL.
S.Th. like
[MustAssign]
public string Val {get; set;]

Do you mean #warning ?
#warning lets you generate a level one warning from a specific location in your code. For example:
#warning Deprecated code in this method.
And for errors, there is (you would never guess), #error.
