在C#中将SQL设置为单用户模式并创建管理员用户可以通过以下步骤实现:
string connectionString = "Data Source=YOUR_SERVER_NAME;Initial Catalog=YOUR_DATABASE_NAME;Integrated Security=True";
string query = "ALTER DATABASE YOUR_DATABASE_NAME SET SINGLE_USER WITH ROLLBACK IMMEDIATE";
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
using (SqlCommand command = new SqlCommand(query, connection))
{
command.ExecuteNonQuery();
}
}
请注意将YOUR_SERVER_NAME和YOUR_DATABASE_NAME替换为实际的SQL Server名称和数据库名称。
string createLoginQuery = "CREATE LOGIN YOUR_LOGIN_NAME WITH PASSWORD = 'YOUR_PASSWORD'";
string alterServerRoleQuery = "ALTER SERVER ROLE sysadmin ADD MEMBER YOUR_LOGIN_NAME";
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
using (SqlCommand command = new SqlCommand(createLoginQuery, connection))
{
command.ExecuteNonQuery();
}
using (SqlCommand command = new SqlCommand(alterServerRoleQuery, connection))
{
command.ExecuteNonQuery();
}
}
请将YOUR_LOGIN_NAME和YOUR_PASSWORD替换为实际的登录名和密码。
