客户端类中中记录异常的方法：使用Log4net

浏览数：24 / 时间：2015年06月09日

1、首先引用Log4Net 的命名空间

using log4net;

2、在使用的类中生命静态变量 log

    public class FileService
   {
       static readonly ILog log = LogManager.GetLogger(typeof(FileService));

.....

3、在 try catch 语句中记录异常信息

try
            {
                operationHandler(fileName);
                return 
FileOperationResult.Successful;
            }
            catch 
(IOException ex)
            {
                log.Info("Unable to save file: " 
+ fileName, ex);
                userMessage = "A problem occured saving the file."; /* TODO: Make localizable resource. */
                ioExceptionOccured = true;
            }
            catch 
(Exception ex) /* TODO: catch common IO errors and report to user. */
            {
                log.Info("Unable to save file: " 
+ fileName, ex);
                var 
userMessageException = ex as 
IUserMessageProvider;
                if 
(userMessageException != null 
&& userMessageException.UserMessagePresent)
                {
                    userMessage = userMessageException.UserMessage;
                }
            }
