尝试附加自动命名的数据库错误 [英] An Attempt to attach an auto-named database Error

问题描述

尝试为文件 C:UsersJohndocumentsvisual studio 2010ProjectsPASPASinDebug//PatAddSys.mdf 附加自动命名的数据库失败.具有相同名称的数据库存在，或者无法打开指定的文件，或者它位于 UNC 共享上."

"An attempt to attach an auto-named database for file C:UsersJohndocumentsvisual studio 2010ProjectsPASPASinDebug//PatAddSys.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."

这里出了什么问题?我的路径有正确的代码(我认为)但这里仍然发生此错误是我的数据库路径

What's wrong here? I have the correct code for my path ( I think) but still this error occurs here is my database path

private string dbPath = Application.StartupPath + "//PatAddSys.mdf";

这是我的数据库的位置

推荐答案

尝试将连接字符串中的用户实例属性设置为 true.您需要将此添加到您的连接字符串:

Try setting the User Instance property in your connection string to true. You need to add this to your connection string:

User Instance=True

还要确保再次检查您的数据库服务器，因为它可能已经包含同名的数据库.

Also just to be sure check again your database server as it might already contain a database with the same name.
