创建一个名为 Log.cs 的类
我正在使用 Linq To SQl 保存到数据库
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Reflection;
using System.Runtime.CompilerServices;
using System.Text;
public static partial class Log
{
/// <summary>
/// Saves the exception details to ErrorLogging db with Low Priority
/// </summary>
/// <param name="ex">The exception.</param>
public static void Save(this Exception ex)
{
Save(ex, ImpactLevel.Low, "");
}
/// <summary>
/// Saves the exception details to ErrorLogging db with specified ImpactLevel
/// </summary>
/// <param name="ex">The exception.</param>
/// <param name="impactLevel">The Impact level.</param>
public static void Save(this Exception ex, ImpactLevel impactLevel)
{
Save(ex, impactLevel,"");
}
/// <summary>
/// Saves the exception details to ErrorLogging db with specified ImpactLevel and user message
/// </summary>
/// <param name="ex">The exception</param>
/// <param name="impactLevel">The impact level.</param>
/// <param name="errorDescription">The error Description.</param>
public static void Save(this Exception ex, ImpactLevel impactLevel, string errorDescription)
{
using (var db = new ErrorLoggingDataContext())
{
Log log = new Log();
if (errorDescription != null && errorDescription != "")
{
log.ErrorShortDescription = errorDescription;
}
log.ExceptionType = ex.GetType().FullName;
var stackTrace = new StackTrace(ex, true);
var allFrames = stackTrace.GetFrames().ToList();
foreach (var frame in allFrames)
{
log.FileName = frame.GetFileName();
log.LineNumber = frame.GetFileLineNumber();
var method = frame.GetMethod();
log.MethodName = method.Name;
log.ClassName = frame.GetMethod().DeclaringType.ToString();
}
log.ImpactLevel = impactLevel.ToString();
try
{
log.ApplicationName = Assembly.GetCallingAssembly().GetName().Name;
}
catch
{
log.ApplicationName = "";
}
log.ErrorMessage = ex.Message;
log.StackTrace = ex.StackTrace;
if (ex.InnerException != null)
{
log.InnerException = ex.InnerException.ToString();
log.InnerExceptionMessage = ex.InnerException.Message;
}
log.IpAddress = ""; //get the ip address
if (System.Diagnostics.Debugger.IsAttached)
{
log.IsProduction = false;
}
try
{
db.Logs.InsertOnSubmit(log);
db.SubmitChanges();
}
catch (Exception eex)
{
}
}
}
}
创建下表
USE [database Name]

GO
影响级别基本上是枚举
public enum ImpactLevel
{
High = 0,
Medium = 1,
Low = 2,
}
你可以如下使用它
try
{
}
catch(Exception ex)
{
//this will save the exception details and mark exception as low priority
ex.Save();
}
try
{
}
catch(Exception ex)
{
//this will save the exception details with priority you define: High, Medium,Low
ex.Save(ImpactLevel.Medium);
}
try
{
}
catch(Exception ex)
{
//this will save the exception details with priority you define: High, Medium,Low
ex.Save(ImpactLevel.Medium, "You can enter an details you want here ");
}
