@Warpten any ideas why this happens? db2 from 7.3.5, stuctures right

[Warpten]

What's the file signature? I'm currently rewriting the entire library under a new namespace. Judging by your error you structure is wrong as it appears to be reading an int32 as a string offset into the stringtable, but that ends up being outside the file, either because a) this file does not have a string table or b) your structure is wrong.

[soulfrost]

library supporting db2 format from 7.3.5 ( 26365 ) ?

[Warpten]

if it's not supported, an exception is thrown.

[soulfrost]

okay, lets me check structure again

[soulfrost]

@Warpten trying to parse with fresh compiled clean TC wpp, 7.3.5.26365 db2 files,

namespace WowPacketParser.DBC.Structures
{
    [DBFile("Achievement")]

    public sealed class AchievementEntry
    {
        public string Title;
        public string Description;
        public string Reward;
        public uint Flags;
        public short InstanceID;
        public ushort Supercedes;
        public ushort Category;
        public ushort UIOrder;
        public ushort SharesCriteria;
        public sbyte Faction;
        public byte Points;
        public byte MinimumCriteria;
        public uint ID;
        public uint IconFileDataID;
        public uint CriteriaTree;
    }
}

and got this

InvocationException: Адресат вызова создал исключение. ---> System.InvalidOperationException: Structure AchievementEntry is missing properties (0 found, 15 expected).

   в DBFilesClient.NET.WDB6.Reader`1.GenerateRecordLoader()
   в DBFilesClient.NET.Reader`1.Load()

   в DBFilesClient.NET.Storage`1..ctor(String fileName, Boolean readOnly)

DBFilesClient.NET.dll version 1.2.0 - latest update from nuget

[Warpten]

Properties, not fields

[soulfrost]

@Warpten still cant solve that issue... can did u help me and say how to fix that problem with properties?

[soulfrost]

[Pveska]

Same problem. Any progress with this issue?
