问题描述

我在Framework 2.0中使用的是log4net，它工作正常.现在，我正在framwork 4.0中构建一个应用程序，并且出现错误.
这是我正在使用的代码.

Hi, I was using log4net in framework 2.0, and it was working fine. Now i am building a app in framwork 4.0 and it is giving an error.
This is the code i am using.

public class DBHelper : IDisposable
    {

       private static readonly log4net.ILog log = log4net.LogManager.GetLogger(typeof(DBHelper));
        private const string EDK = "11d50a3a";
        private static Hashtable connStrings = new Hashtable();
        private const bool m_bUseDummyReader = true;
        DbTransaction transaction;
        IDbConnection connection;        

        private string databaseName;
        private Database CurrDB;

        cfsEncryption cfsEncrypt = new cfsEncryption();

        public DBHelper(string strDB)
        {            
            Init(strDB, IsolationLevel.ReadCommitted);
        }
        private void Init(string strDB, IsolationLevel iso)
        {

            databaseName = strDB;
            try
            {
                CurrDB = DatabaseFactory.CreateDatabase(strDB);
                connection = CurrDB.CreateConnection();
                connection.Open();
                transaction = (DbTransaction)connection.BeginTransaction();

            }
            catch (Exception ex)
            {
                if ((log.IsErrorEnabled))
                    log.Error(string.Format(System.Globalization.CultureInfo.CurrentCulture,
                        "Connection to DB ->{0} Failed", strDB), ex);

                throw;
            }
        }

这是我遇到的错误.

推荐答案

log4net DLL可能是为x86构建的，并且您在64位或vise上运行-反之亦然.

尝试从源代码编译log4net并更改目标平台以匹配您的主项目.

The log4net DLL was probably built for x86 and you are running on 64bit or vise-versa.

Try compiling the log4net from source and changing the target platform to match your main project.
