如何手动创建的LocalDB使用MDF文件？ [英] How to manually create a mdf file for localdb to use?

问题描述

我设置了​​一些单元测试与数据库进行测试工作。我想用的LocalDB V11，但首先我需要创建数据库。我究竟是如何做的呢？

I'm setting up some unit tests for testing work done with a database. I would like to use localdb v11 but first I need to create the database. How exactly do I do this?

简单地连接到（的LocalDB）V11 在SQL Management Studio中我连接到（我认为）是 C中的数据库：\用户\乔治\ 。如何指定一个新的？

simply connecting to (localdb)v11 in sql management studio connects me to the database that (I assume) is in C:\Users\George\. How do I specify a new one?

在code使用说明书ADO.Net，没有实体框架，以便据我所知，我不能依靠它来简单地创建数据库。

The code uses manual ADO.Net, not Entity Framework so as far as I know I cannot rely on it to simply create the database.

推荐答案

只需使用CREATE DATABASE语句

Just use CREATE DATABASE statement

SqlConnection connection = new SqlConnection(@"server=(localdb)\v11.0");
using (connection)
{
    connection.Open();

    string sql = string.Format(@"
        CREATE DATABASE
            [Test]
        ON PRIMARY (
           NAME=Test_data,
           FILENAME = '{0}\Test_data.mdf'
        )
        LOG ON (
            NAME=Test_log,
            FILENAME = '{0}\Test_log.ldf'
        )",
        @"C:\Users\George"
    );

    SqlCommand command = new SqlCommand(sql, connection);
    command.ExecuteNonQuery();
}
