C＃错误帮助C＃C＃错误帮助C＃数据库 [英] C# Error Help C# C# Error Help C# Database

问题描述

大家好。

i对C＃来说是新手，但我一直都会遇到这个错误，现在让我感到紧张。

我创建了一个数据库，当我尝试访问我的数据库： -

Hi guys
i am sort of new to C# but i keep getting this one error which is now getting my nerves.
I have created a database and when i try access my database :-

private void button3_Click(object sender, EventArgs e)
       {
           TillDatabaseEntities tde = new TillDatabaseEntities();

       }

然后我得到这个错误，我希望这是有道理的。如果确实可以帮到我吗？





以下方法或属性之间的调用不明确：'Till_System.TillDatabaseEntities.TillDatabaseEntities （）'和'Till_System.TillDatabaseEntities.TillDatabaseEntities（）'

i then get this error , i hope this makes sense. if it does can you help me please?


The call is ambiguous between the following methods or properties: 'Till_System.TillDatabaseEntities.TillDatabaseEntities()' and 'Till_System.TillDatabaseEntities.TillDatabaseEntities()'

推荐答案

我的猜测是你引用了两个不同的程序集（可能是两个不同位置的相同DLL） 。



我刚刚在几分钟前处理过这个问题。我的一个项目是引用旧版本的DLL，而我的另一个项目是引用了较新版本。

My guess is that you have two different assemblies referenced (possibly the same DLL in two different locations).

I just dealt with that issue myself a couple minutes ago. One of my projects was referencing an older version of a DLL, and another of my projects was referencing the newer version.
