尝试为文件附加自动命名的数据库失败。存在具有相同名称的数据库 [英] An attempt to attach an auto-named database for file failed. A database with the same name exists

问题描述

我已经多次看过这样的话题了，他们告诉我们把用户实例设为true来传递这个execption。当我在visual studio中执行我的程序时，几乎所有的东西都没问题但是当我为它构建一个设置并再次执行时，这个例子出现了！我该怎么办？！？对我来说非常重要。

i have seen such as this topic many times and they told to put user instance true to pass this execption . when i execute my programme in visual studio ,almost every things is ok but when i build a setup for that and again execute ,this exeption appear ! what should i do?!?it is very important for me.

推荐答案

首先检查一下你的文件夹是不是只读的。它适合我。第二个再次检查你的连接字符串。同时检查User Instance = True

First one check that your folder is not read-only. It Worked for me. Second one again check your connection string. Also check User Instance=True
