一个或多个实体的验证失败 [英] Validation failed for one or more entities

问题描述

我的asp.net MVC3应用程序中有以下代码：

  string msg =开始报告运行为：; 
 msg + =Obligor Registry ID：+ obligorID; 
 msg + =请求组织注册表ID：+ requestsOrgID; 
 msg + =请求代理注册表ID+ requestAgentID; 
 
 TransactionLog lg = new TransactionLog（）; 
 lg.TransactionTypeId = 2; 
 lg.Message = msg; 
 
 
 context.TransactionLogs.Add（lg）; 
 long referenceNumber = context.SaveChanges（）; 
 return referenceNumber; 
  

我收到以下错误：

 一个或多个实体的验证失败。有关详细信息，请参阅EntityValidationErrors属性。 
  

解决方案

当您处于 catch {...} 块打开QuickWatch窗口（ ctrl + alt + q ）并粘贴在那里：

（（System.Data.Entity.Validation.DbEntityValidationException）ex）.EntityValidationErrors

这将允许您深入到 ValidationErrors 树中。这是我找到的最简单的方法来即时了解这些错误。

I have following code in my asp.net MVC3 application:

string msg = "Beginning report run for: ";
            msg += " Obligor Registry ID: " + obligorID;
            msg += " Requesting Organization Registry ID:" + requestingOrgID;
            msg += " Requesting Agent Registry ID: " + requestingAgentID;

            TransactionLog lg = new TransactionLog();
            lg.TransactionTypeId = 2;
            lg.Message = msg;    


             context.TransactionLogs.Add(lg);
             long referenceNumber = context.SaveChanges();
            return referenceNumber;

and I am getting following error:

Validation failed for one or more entities. See 'EntityValidationErrors' property for more details. 

解决方案

While you are in debug mode within the catch {...} block open up the "QuickWatch" window (ctrl+alt+q) and paste in there:

((System.Data.Entity.Validation.DbEntityValidationException)ex).EntityValidationErrors

This will allow you to drill down into the ValidationErrors tree. It's the easiest way I've found to get instant insight into these errors.
