説明
Description
When creating an enumeration via the DefineEnum on the ModuleBuilder, the emitted type's UnderlyingSystemType is set to the type being emitted (creating a circular reference path). It should be set to the provided type.
Reproduction Steps
ModuleBuilder _moduleBuilder = AssemblyBuilder.DefineDynamicAssembly(new AssemblyName("Test"), AssemblyBuilderAccess.RunAndCollect).DefineDynamicModule("Test");
EnumBuilder builder = _moduleBuilder.DefineEnum("E_Test", TypeAttributes.Public, typeof(int));
builder.DefineLiteral("Low", 0); builder.DefineLiteral("High", 1);
Type type = builder.CreateType();
if (type.UnderlyingSystemType == type) { throw new Exception("Circular reference"); } else if (type.UnderlyingSystemType != builder.UnderlyingSystemType) { throw new Exception("This should never throw"); }
Expected behavior
Emitted type has the underlying type set to the type defined in the DefineEnum call ("Circular reference" exception will be thrown)
Actual behavior
Emitted type has the underlying type set to itself
