CSFrameworkV6 - .NET敏捷开发之道 - Exception异常扩展类

BizException异常扩展类

该类可以显示系统异常详情，包括【异常类型】、【异常信息】、【异常方法】、【堆栈调用】以及【EF内部异常】 DbEntityValidationException异常。

开发人员根据异常提示消息定位问题快速解决问题，提高开发效率！

Exception扩展类

C# Code:

/// <summary>
/// www.csframework.com .NET敏捷开发之道
/// </summary>
public static class EFExceptionExtension
{
/// <summary>
/// 获取异常信息
/// </summary>
/// <param name="ex">异常实例</param>
/// <param name="showStackTrace">获取堆栈信息</param>
/// <param name="Prefix"></param>
/// <returns></returns>
public static string GetMessageEF(this Exception ex, bool showStackTrace = false, string Prefix = "")
{
StringBuilder sb = new StringBuilder();

sb.AppendLine(Prefix + "【异常类型】∶" + ex.GetType().Name);
sb.AppendLine(Prefix + "【异常信息】:" + ex.Message);
sb.AppendLine(Prefix + "【异常方法】:" + ex.TargetSite);

if (showStackTrace)
sb.AppendLine(Prefix + "【堆栈调用】:" + ex.StackTrace);

//EF框架校验实体异常
if (ex is DbEntityValidationException efex)
{
if (efex.EntityValidationErrors.Count() > 0)
{
var sb1 = new StringBuilder();
foreach (var v in efex.EntityValidationErrors)
{
sb1.AppendLine(String.Join("\r\n", v.ValidationErrors.Select(s => s.ErrorMessage).ToList()));
};
if (sb1.Length > 0)
sb.AppendLine(Prefix + "【EF内部异常】:" + sb1.ToString());
}
}

//Exception内部异常
if (ex.InnerException != null)
{
sb.AppendLine(Prefix + "【InnerException】:" + ex.InnerException.Message);

if (ex.InnerException.InnerException != null)
sb.AppendLine(ex.InnerException.InnerException.Message);

}
return sb.ToString();
}
}

使用方法

C# Code:

catch (Exception ex)
{
db.RollbackTransaction();
throw new BizException(ex.GetMessageEF());
}

BizException

C# Code:

public class BizException : Exception
{
public BizException();
public BizException(string message);
public BizException(int errorCode, string message);

public int ErrorCode { get; set; }
}
