c# - CultureName of System assembly in .NET -


while writing code handling assemblies in c# noticed inconsistencies in field values of assembly object (example of system assembly):

> typeof(string).assembly.fullname "mscorlib, version=4.0.0.0, culture=neutral, publickeytoken=b77a5c561934e089"

but when accessing culturename field of assemblyname object directly, value empty string:

> typeof(string).assembly.getname().culturename ""

when run same test on linux (mono 3.99) got result:

> typeof(string).assembly.getname().culturename "neutral"

why .net behaves way? couldn't find information on msdn regarding default value of culturename field in assemblyname class or meaning of empty string. empty string refers "neutral" culture name?

the culturename property introduced in .net 4.5 , value of property assembly neutral culture must equal empty string name of invariant culture because culturename uses thecultureinfo property (source):

public string culturename {         {         return (_cultureinfo == null) ? null : _cultureinfo.name;     } }

but in mono culturename property has different implementation (source). why different? think developers of mono know answer.

public string culturename {      {          if (cultureinfo == null)              return null;          if (cultureinfo.lcid == cultureinfo.invariantculture.lcid)              return "neutral";          return cultureinfo.name;      }  }

so if want check assemblyname has neutral culture, use code below:

if (object.equals(assemblyname.cultureinfo, cultureinfo.invariantculture)) { /* neutral culture */ }
