1.新建一个 Visual Basic .net Windows 应用程序项目。默认情况下，将 Form1 添加到项目中。
2.在 Form1 上放一个 Command 按钮，并将其 Name 属性更改为 btnCreateDatabase，将其 Text 属性更改为 Create Database。
3.复制下面一行代码并粘贴到 Form1 的“general declaration”部分： Imports System.Data.SqlClient
4.复制下面的代码并粘贴到“Windows Form Designer generated code”区域之后：
Private Sub btnCreateDatabase_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnCreateDatabase.Click
Dim reader As SqlDataReader
Dim str As String
Dim myConn As SqlConnection = New SqlConnection("Server=(local)\netsdk;" & _
"uid=sa;pwd=;database=master")
str = "CREATE DATABASE MyDatabase ON PRIMARY " & _
"(NAME = MyDatabase_Data, " & _
" FILENAME = 'D:\MyFolder\MyDatabaseData.mdf', " & _
" SIZE = 2MB, " & _
" MAXSIZE = 10MB, " & _
" FILEGROWTH = 10%) " & _
" LOG ON " & _
"(NAME = MyDatabase_Log, " & _
" FILENAME = 'D:\MyFolder\MyDatabaseLog.ldf', " & _
" SIZE = 1MB, " & _
" MAXSIZE = 5MB, " & _
" FILEGROWTH = 10%) "
Dim myCommand As SqlCommand = New SqlCommand(str, myConn)
Try
myConn.Open()
reader = myCommand.ExecuteReader()
Catch ex As Exception
MessageBox.Show(ex.ToString())
Finally
If Not reader Is Nothing Then
reader.Close()
If (myConn.State = ConnectionState.Open) Then
myConn.Close()
End If
MessageBox.Show("Database is created successfully", _
"MyProgram", MessageBoxButtons.OK, _
MessageBoxIcon.Information)
End If
End Try
End Sub
5.更改连接字符串使其指向 SQL Server，要确保将 Database 参数设置为 Master 或保留为空白。
6.按 F5 键或 CTRL+F5 组合键以运行该项目，然后单击创建数据库。
其他注意事项
此代码创建的是带有特定属性的自定义数据库。
将要保存所创建 .mdf 和 .ldf 文件的文件夹必须在运行该代码之前就已存在、否则会引发异常。
如果想创建一个类似于 SQL Server 的 Model 数据库的数据库并想让它存储在默认位置，那么请更改代码中的 str 变量： str = "CREATE DATABASE MyDatabase"
