How do I create a database programatically in SQL Server?

Question

I would like to create a new database from my C# application.
How can I do that?

I'm assuming once I create it, I can simply generate a connection string on the fly and connect to it, and the issue all the CREATE TABLE statements.

Answer 1

There's probably an uber-leet way of doing this, but why not just connect to the master database and feed in some sql?

Answer 2

Look into the CREATE DATABASE statement.

Answer 3

KB307283 explains how to create a database using ADO.NET.

From the article:

String str;
SqlConnection myConn = new SqlConnection ("Server=localhost;Integrated security=SSPI;database=master");

str = "CREATE DATABASE MyDatabase ON PRIMARY " +
    "(NAME = MyDatabase_Data, " +
    "FILENAME = 'C:\\MyDatabaseData.mdf', " +
    "SIZE = 2MB, MAXSIZE = 10MB, FILEGROWTH = 10%) " +
    "LOG ON (NAME = MyDatabase_Log, " +
    "FILENAME = 'C:\\MyDatabaseLog.ldf', " +
    "SIZE = 1MB, " +
    "MAXSIZE = 5MB, " +
    "FILEGROWTH = 10%)";

SqlCommand myCommand = new SqlCommand(str, myConn);
try 
{
    myConn.Open();
    myCommand.ExecuteNonQuery();
    MessageBox.Show("DataBase is Created Successfully", "MyProgram", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
catch (System.Exception ex)
{
    MessageBox.Show(ex.ToString(), "MyProgram", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
finally
{
    if (myConn.State == ConnectionState.Open)
    {
        myConn.Close();
    }
}
