现在Silverlight 2终于出货了。我想知道是否有人为它组合了任何日志框架,或许像enterprise library logging或log4net?我对一些可以执行跟踪客户端并将消息记录到服务器的东西感兴趣。Silverlight日志记录框架和/或最佳实践
到目前为止,我发现的唯一项目是Clog在CodeProject。有没有人使用过?你对此有何想法?

我正在为我们写的产品钻研类似的东西。我正在考虑使用PostSharp for Silverlight将客户端日志记录添加为一个方面。
我已经使用了大获成功的NLOG项目之前下足.NET Framework和Compact Framework的,所以我将最有可能利用现有的框架代码,并添加一些记录目标:
我简单地看过Clog,它似乎有一个主要缺陷 - 它无法记录连接失败。因此,假设您的Web服务器始终处于联机状态,可以,但是当上游或服务器本身发生问题时,日志记录数据将全部丢失,甚至可能会导致应用程序崩溃。
我已经结束了从头开始写一个新的日志框架,解决这个缺陷。我创建了一个本地队列,它将获取日志/跟踪消息,然后执行过滤并将它们发送到服务器。然后,队列将由独立存储提供支持,因此即使客户端在该会话中永久离线,消息也会在其恢复联机时发送。
如果您只是想将调试消息输出到控制台。您可以使用浏览器的console.log机制。我编写了一个扩展方法。你可以在my blog找到。

public static string Log(string message)
{
var msgLog = "";
try
{
HtmlWindow window = HtmlPage.Window;
//only log if a console is available
var isConsoleAvailable = (bool)window.Eval("typeof(console) != 'undefined' && typeof(console.log) != 'undefined'");
if (!isConsoleAvailable) return "isConsoleAvailable " + isConsoleAvailable;
var createLogFunction = (bool)window.Eval("typeof(ssplog) == 'undefined'");
if (createLogFunction)
{
// Load the logging function into global scope:
string logFunction = @"function ssplog(msg) { console.log(msg); }";
string code = string.Format(@"if(window.execScript) {{ window.execScript('{0}'); }} else {{ eval.call(null, '{0}'); }}", logFunction);
window.Eval(code);
}
// Prepare the message
DateTime dateTime = DateTime.Now;
string output = string.Format("{0} - {1} - {2}", dateTime.ToString("u"), "DEBUG", message);
// Invoke the logging function:
var logger = window.Eval("ssplog") as ScriptObject;
logger.InvokeSelf(output);
}
catch (Exception ex)
{
msgLog = "Error Log " + ex.Message;
}
return msgLog;
}
我正在使用JavaScript窗口并在Silverlight中对其进行脚本编写。对于“生产”,我可以关闭此窗口,但仍将日志行保存到内存中,如果出现问题,请将其发送到服务器。这样我就可以得到两全其美的效果 - 在客户端上进行简单,实时的日志记录以进行调试,并记录用户可能遇到的远程验尸情况。
如果你愿意把你的宇航员头盔关闭一分钟,下面是我为Silverlight编写的一个轻量级记录器,用于客户端记录(主要用于WCF操作,但可能用于任何错误) 。
它最初用于iPhone应用程序的Monotouch,并且已被改编为IsolateStorage
。如果需要,您可以使用Read
方法在文本框中显示。经过SL4测试。
