自定义错误日志记录类

引言

　　这是一个简单的自定义的错误日志记录类，这里我主要用于API接口开发中，APP移动端的入参记录

日志参数

/// <summary>
    /// 日志参数
    /// </summary>
    public static class LogReq
    {
        /// <summary>
        /// 入参
        /// </summary>
        public static string LogReqStr = "";
        /// <summary>
        /// 加密后入参
        /// </summary>
        public static string DesCryptStr = "";
        /// <summary>
        /// 联众请求
        /// </summary>
        public static string LogMintInfoStr = "";
    }

错误日志定义类

public class LogClass
    {
        private string logFile;
        private StreamWriter writer;
        private FileStream fileStream = null;
        private string ReqStr = LogReq.LogReqStr;//APP请求入参
        private string DesCryptStr = LogReq.DesCryptStr;//APP请求入参[加密后]
        private string MediInfoReq = LogReq.LogMintInfoStr;//联众请求入参
        public LogClass(string fileName)
        {
            logFile = fileName;
            CreateDirectory(logFile);
        }

        /// <summary>
        /// 系统错误报告
        /// </summary>
        /// <param name="ex"></param>
        public void ExcLog(Exception ex)
        {

            try
            {
                FileInfo fileInfo = new FileInfo(logFile);
                if (!fileInfo.Exists)
                {
                    fileStream = fileInfo.Create();
                    writer = new StreamWriter(fileStream);
                }
                else
                {
                    fileStream = fileInfo.Open(FileMode.Append, FileAccess.Write);
                    writer = new StreamWriter(fileStream);
                }
                writer.WriteLine("当前时间：" + DateTime.Now);
                writer.WriteLine("加密后入参：" + DesCryptStr);
                writer.WriteLine("入参信息：" + ReqStr);
                writer.WriteLine("联众请求入参：" + MediInfoReq);
                writer.WriteLine("异常信息：" + ex.Message);
                writer.WriteLine("异常对象：" + ex.Source);
                writer.WriteLine("调用堆栈：
" + ex.StackTrace.Trim());
                writer.WriteLine("触发方法：" + ex.TargetSite);
                writer.WriteLine();
                writer.Close();

            }
            finally
            {
                if (writer != null)
                {
                    writer.Close();
                    writer.Dispose();
                    fileStream.Close();
                    fileStream.Dispose();
                }
            }
        }

        /// <summary>
        /// 自定义错误报告
        /// </summary>
        /// <param name="ex"></param>
        public void ExcLog(CustomerException ex)
        {

            try
            {
                FileInfo fileInfo = new FileInfo(logFile);
                if (!fileInfo.Exists)
                {
                    fileStream = fileInfo.Create();
                    writer = new StreamWriter(fileStream);
                }
                else
                {
                    fileStream = fileInfo.Open(FileMode.Append, FileAccess.Write);
                    writer = new StreamWriter(fileStream);
                }
                writer.WriteLine("当前时间：" + DateTime.Now);
                writer.WriteLine("入参信息：" + ReqStr);
                writer.WriteLine("加密后入参：" + DesCryptStr);
                writer.WriteLine("联众请求入参：" + MediInfoReq);
                writer.WriteLine("异常代码：" + (int)ex.Code);
                writer.WriteLine("异常信息：" + ex.Msg);
                writer.WriteLine();
                writer.Close();

            }
            finally
            {
                if (writer != null)
                {
                    writer.Close();
                    writer.Dispose();
                    fileStream.Close();
                    fileStream.Dispose();
                }
            }
        }

        public void CreateDirectory(string infoPath)
        {
            DirectoryInfo directoryInfo = Directory.GetParent(infoPath);
            if (!directoryInfo.Exists)
            {
                directoryInfo.Create();
            }
        }
    }

使用例子（指定路径）

　　var log = new Log.LogClass("E:\website\NanChang\ExcLog\" + DateTime.Now.ToString("yyyyMMdd") + "_Log.txt");
　　log.ExcLog(ex);

PS：如果需要自定义路劲的话，请自行修改哈
