我正在使用 log4net 并记录异常。但我想在异常时间记录当前对象，但我做不到。我创建了异常并将对象添加到异常的数据属性中，然后通过 log4net 记录异常。log4net 的异常消息不包含我的对象。

我的代码，例如；

 try
                {
                    Exception exp = new Exception("critical error");
                    exp.Data.Add("Eror Object", viewModel);
                    throw exp;
                }
                catch (Exception exp)
                {
                    _logManager.Error(exp);

                }

我的 viewModel 对象；

 [Serializable]
    public class CartTransferViewModel
    {
        public CartTransferViewModel()
        {
            Model = new ModelObject();
        }
        public ModelObject Model { get; set; }
        public string InformatinMessage { get; set; }
        public bool? IsActive { get; set; }
    }

我的模型对象也是可序列化的。但是 log4Net 的异常信息是这样的；

System.Exception: critical error
   at FooProject.FooClass.FooMethod() in d:\FooProject\FooClass.cs:line 200

我删除可序列化属性然后重新运行我的应用程序，错误代码确实更改为；

System.ArgumentException: Argument passed in is not serializable.
Parameter name: value
   at System.Collections.ListDictionaryInternal.Add(Object key, Object value)
   at FooProject.FooClass.FooMethod() in d:\FooProject\FooClass.cs:line 200

如何用我的对象记录我的自定义异常？

好的，如果我有你的问题。我做类似的事情。我使用记录器来编写异常。但我使用 Exception.Data 属性。

这是示例，示例包含 1) Info 类，需要编写 2) 带有方法的示例类，发生异常时编写 infoclass 3) 格式化异常的实用程序类

 [Serializable]
    public class FlatFileItem
    {
        ArrayList errorlist = new ArrayList();

        public FlatFileItem()
        {
            if (errorlist == null) { errorlist = new ArrayList(); }
        }

        //Name of the file
        public string FileName { get; set; }
        public override string ToString()
        {
            return string.Format(@"FlatFileItem (Unzip FTPLineItem) => FileName:{0}",  this.FileName);
        }
    }


public class someclass {
    public void somemethod(){
        try{
            // throw exception here
        } catch (Exception ex)
                    {
                        ex.Data["flatfile"] = Convert.ToString(flatfile);  //Using data property
                        flatfile.HasErrors = true;  //not there in above example
                        flatfile.Parent.AddErrorInfo(ex); //not there in above example
                        logger.Error(String.Format(ex.Message)); //not there in above example

                        throw ( new Exception ("yourmsg",ex)); //if you want to do this
                    }
    }
}

//现在我使用这个实用方法在非常顶级的异常中写出所有内容

 public class ExceptionInfoUtil
{
    public static string GetAllExceptionInfo(Exception ex)
    {
        StringBuilder sbexception = new StringBuilder();

        int i = 1;
        sbexception.Append(GetExceptionInfo(ex, i));

        while (ex.InnerException != null)
        {
            i++;
            ex = ex.InnerException;
            sbexception.Append(GetExceptionInfo(ex, i));
        }

        return sbexception.ToString();
    }

    private static string GetExceptionInfo(Exception ex, int count)
    {
        StringBuilder sbexception = new StringBuilder();
        sbexception.AppendLine(string.Format(""));
        sbexception.AppendLine(string.Format(""));

        sbexception.AppendLine(string.Format("************************************************"));

            string skey = string.Empty;
            foreach (object key in ex.Data.Keys)
            {
                try
                {
                    if (key != null)
                    {
                        skey = Convert.ToString(key);
                        sbexception.AppendLine(string.Format(" Key :{0} , Value:{1}", skey, Convert.ToString(ex.Data[key])));
                    }
