EnterPrise Library Logging

昨天搞了一晚上，总算把EnterPrise Library Loggin 搞明白了。

创建好就应用后，用Enterprise Library Configuration打开Web.Config或App.Config.

新建Logging Application Block，先在Trace Listeners 新建几个Trace Listeners（是配置写入不同物理位置）如：
flat File Trace Listener 写入文件
DataBase Trace Listener 写入数据库（配置数据库简单不说了，用带的建库SQL建库就好了）

然后在Category Sources 创建几个节点分别设置Trace Listeners

protected void Button1_Click(object sender, EventArgs e)
        {
            LogEntry errLog = new LogEntry();
            errLog.Message = this.TextBox1.Text;
            errLog.Severity = System.Diagnostics.TraceEventType.Error;//设定消息类型
            Logger.Write(errLog, "Message");//Message 是以上Category Sources 定义的名称
        }

        protected void Button2_Click(object sender, EventArgs e)
        {
            LogEntry errLog = new LogEntry();
            errLog.Message = this.TextBox2.Text;
            errLog.Severity = System.Diagnostics.TraceEventType.Information;
            Logger.Write(errLog, "Error");
        }

        protected void Button3_Click(object sender, EventArgs e)
        {
            LogEntry errLog = new LogEntry();
            errLog.Message = this.TextBox3.Text;
            errLog.Severity = System.Diagnostics.TraceEventType.Information;
            Logger.Write(errLog, "Operator");
        }
