We use negative numbers for the compiler, and leave the possitive
numbers to match the Microsoft numbers.
NOTE: I am now moving to use numbers above 6000 instead of negative
numbers, as they look nicer on the debugging output.
-1 An Primary Expression was parsed, when a Type was expected.
This happens because my parser knowledge is limited, and I
am not good at writing grammars. It is still an error,
but if I were smarter, I would have found a Bison/Yacc way
of handling it.
-2 Internal error, an interface is being defined inside an
interface (This should never happen).
-3 Constant type is not one of sbyte, byte, short, ushort, int,
uint, long, ulong, char, float, double, decimal, bool, string, enum
or null type.
-5 A search for a name on a Type returned matches that contain
methods and non-methods. They have the same name, and I do
not know how this is possible to begin with.
-6 Generic internal compiler error.
-7 Internal compiler error/library error: no default constructor
for a built-in type. Ie, decimal (int 32)
-8 User-defined conversion cannot convert from or to object type.
-9 User-defined conversion cannot convert from or to an interface type.
-10 User-defined conversion cannot convert between types that derive
from each other.
-12 More than one integral conversion exists for the type on a
switch statement.
-13 No return with a value found. Warning, since we currently
do not perform flow analysis, and can not tell whether a
ret is required or not.
-14 Invalid number passed to probe
-15 Can not locate default assembly path
-16 Can not use System.Enum.ToObject (type, ConstantValue) with
user defined types.
-17 A type has already been defined (try --nostdlib)
-18 Do not know how to generate debugging information for this platform.
-19 Can not find required utility function in the core libraries.
-20 Cannot find attribute type Blah (maybe you forgot to set the
usage using the AttributeUsage attribute ?).
-21 Bug in Microsoft compiler while applying named attribute for
StructLayout.CharSet value.
-22 Location of previous error
-23 .NET runtime error when encoding attributes whose constructor
takes an object, but an enumeration value that is boxed is
passed.
Sample:
using System.ComponentModel;
[DefaultValue (CollectionChangeAction.Add)]
class X { static void Main () { } }
-24 .NET runtime bug when trying to set custom attributes on the
return type of a method
-25 Generic parse error
-26 Corlib compilation is not supported in MS.NET
-27 Attribute resolved to two different types
-28 (retired)
-29 Use -option instead of --option: to move people to the new
command line handling.
-30 This version of the runtime does not support making pinned local variables.
This code may cause errors on a runtime with a moving GC
-31 Internal compiler error during the method emit phase.
-32 Internal compiler error during parsing.
-33 Contravariant type parameters cannot be the return type.
-34 Contravariant type parameters can only be used as type arguments in
contravariant positions.
-35 Covariant type parameters can only be used as type arguments in
covariant positions.
-36 Variant type parameters can only be used with interface and
delegate types.
-37 Contravariant type parameters cannot be byref method parameters.
-38 Covariant type parameters cannot be used as method parameters.
----------
Errors that we have allocated that will have corresponding errors in
the Microsoft C# compiler:
-200 Constraints for class defined, but there is no parameter list.
-201 Class containing main method is generic.
-202 Can not use a type parameter in an attribute.
-203 Can not use type parameters as unmanaged types.
-204 yield statement in something which is not a method-body,
accessor-body or operator-body
-205 A method containing a yield statement is not IEnumerator.
-206 Return statement not allowed inside iterators.
-207 A parameter in an enumerator method contains out or ref
-208 Yield statement appears inside finally clause
-209 Yield statment appears in anonymous method.
-210 Fixed code not allowed inside iterators.
-211 Array expression passed to attribute is not unidimensional
-212 An Array creation expression is present, but the array is not
initialized.
-213 This feature requires v2 support.
-214 Generic class can not have attribute as its parent class
-215 Taking the address of a parameter in an iterator is not allowed.
-216 Can not use a type parameters as base class
-217 Wrong number of type parameters
-218 Invalid constraints clause
-219 Type argument doesn't meet constraints.
-220 Cannot resolve constructed type
-221 params modifier present in anonymous method declaration
-222 yield statement only available in C# 2.0 mode
