Hereis a post from MSDN explaining how to do it using SMO:
这是 MSDN 上的一篇文章，解释了如何使用 SMO 做到这一点：
using System.Data.SqlClient;
using System.IO;
using Microsoft.SqlServer.Management.Common;
using Microsoft.SqlServer.Management.Smo;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string sqlConnectionString = "Data Source=(local);Initial Catalog=AdventureWorks;Integrated Security=True";
FileInfo file = new FileInfo("C:\myscript.sql");
string script = file.OpenText().ReadToEnd();
SqlConnection conn = new SqlConnection(sqlConnectionString);
Server server = new Server(new ServerConnection(conn));
server.ConnectionContext.ExecuteNonQuery(script);
}
}
}

When I need to run sql scripts containing GO statements I usually read the entire file into a string and split it into a string array using GO as the delimiter.
当我需要运行包含 GO 语句的 sql 脚本时，我通常将整个文件读入一个字符串，并使用 GO 作为分隔符将其拆分为一个字符串数组。
I then connect to the database and run each statement in order.
然后我连接到数据库并按顺序运行每个语句。
It's quite easy and works well. Just make sure to keep your database connection open while running all statements. Also you may consider running them all in a transaction.
这很容易并且运行良好。只需确保在运行所有语句时保持数据库连接打开。你也可以考虑在一个事务中运行它们。
