c# 如何阻止异常冒泡

Question

当我的控制器中抛出异常时，操作会一次又一次地执行，当抛出错误时，此循环将继续。

 try
  {
                    LogManager.Info("Call:" + invocation.TargetType.Name + "::" + invocation.Method.Name);
                    var startTime = DateTime.Now;
                    invocation.Proceed();
                    var endTime = DateTime.Now;
                    LogManager.Info("CallEnd:" + invocation.TargetType.Name + "::" + invocation.Method.Name + " Execution Time(Milliseconds): " + (endTime - startTime).Milliseconds);
                }
                catch (Exception ex)
                {                
                    //HttpContext.Current.Request.Abort();
                    var builder = new StringBuilder();
                    var dataSource = ConfigurationManager.ConnectionStrings["dbMain"].ToString().Split(';')[0];

                    builder.AppendLine();
                    builder.AppendLine(string.Concat(Enumerable.Repeat(">", 50)));
                    builder.AppendLine("Server Time:-" + DateTime.Now);
                    //builder.AppendLine("Requested Url:" + HttpContext.Current.Request.Url);
                    builder.AppendLine(dataSource);
                    builder.AppendLine("Error at " + invocation.TargetType.Name + "::" + invocation.Method.Name + "(" + JsonConvert.SerializeObject(invocation.Arguments, Formatting.Indented) + ")");
                    builder.AppendLine(string.Concat(Enumerable.Repeat("-", 50)));
                    builder.AppendLine(JsonConvert.SerializeObject(ex, Formatting.Indented).Replace("\n", System.Environment.NewLine));
                    builder.AppendLine(string.Concat(Enumerable.Repeat("<", 50)));

                    LogManager.Error(builder.ToString());
                    LogManager.SendMail(ex, builder.ToString());

                    throw;
                }

如果您希望异常停止冒泡，请不要重新抛出它。在您的代码中有： "throw ;" 行。删除它。
