添加以下参考文献：

c：\ Program Files \ Microsoft SQL
服务器\ 100 \ SDK \装配\ Microsoft.SqlServer.Smo.dll
C：\ Program Files（x86）\ Microsoft SQL Server \ 100 \ SDK \ Assemblies \ Microsoft.SqlServer.Management.Sdk.Sfc.dll

在App config中请注意以下片段

<startup useLegacyV2RuntimeActivationPolicy="true">
  <supportedRuntime version="v4.0"/>
</startup>

代码：

var myConn = "Server=localhost;Integrated security=SSPI;database=master";

//The CREATE DATABASE statement failed. The primary file must be at least 3 MB to accommodate a copy of the model database.
var command = @"
CREATE DATABASE myDB
ON PRIMARY 
(
NAME = MyDatabaseData, 
FILENAME = 'C:\Temp\MyDatabaseData.mdf', 
SIZE = 3MB,
FILEGROWTH =10%
) 
LOG ON 
(
NAME =MyDatabaseLog, 
FILENAME = 'C:\Temp\MyDatabaseLog.ldf', 
SIZE = 1MB, 
FILEGROWTH =10%
)";

using (var conn = new SqlConnection(myConn))
{
  try
  {
    var server = new Server(new ServerConnection(conn));
    server.ConnectionContext.ExecuteNonQuery(command);
  }
  catch (Exception e)
  {
    Console.WriteLine(e.Message);

  }
}
