Creating a database instance in C#

Is it possible to create开发者_如何学运维 a sql database instance with C# code. I have no problem adding a database to an existing SQL instance, for example WONEA\SQLEXPRESS but for creating another SQL instance such as WONEA\SQLEXPRESSTEST I'm a little stumped. Help!

The short answer is you can't do this using C# code.

SQL server instances are essentially installations of SQL server - in order to create a new SQL server instance you need to run the SQL Server installer, and ask it to install one (which you can technically do from C# code, but I gather thats not the answer you were looking for).

Creating new instances requires running the installer for SQL server, so I would imagine the answer is "No." (Would be interested to hear otherwise though!)

You could use a command prompt process to create a SQL instance if you have SQL Local DB installed. See code example below:

Process proc = new Process();
ProcessStartInfo info = new ProcessStartInfo
{
     FileName = "cmd.exe",
     Arguments = $"/C {argument}",
     RedirectStandardOutput = true,
     UseShellExecute = false,
     CreateNoWindow = true
};

proc.StartInfo = info;
proc.Start();

Where Argument is a string parameter that looks something like this:

sqllocaldb create "SqlInstance"

This instruction will create a new SQL instance called SqlInstance.
