VB.NET 通过MySQLDriverCS连接Mysql

1. 通过https://sourceforge.net/projects/mysqldrivercs/下载MysqLDriverCS安装程序，安装到本地电脑上，（后续不需要每台电脑都安装此程序），找到安装位置中的dll文件夹，
2. 在.net程序中引用上面文件夹中的MysqLDriverCS.dll文件，并在代码中导入,并把 MysqLDriverCS.dll， libMysqL.dll，libMysqL-4.0.dll拷贝到项目文件夹中

Imports MysqLDriverCS

3.

Try
    Dim MysqL As String = "Location=10.*.*.*;User Id=root;Data Source=;Port=3306;Password="
    'Dim MysqL As String = "server=localhost;User Id=root;Data Source=;Port=3306;Password="
    Dim Connection As New MysqLConnection(MysqL)
    Connection.open()   '打开数据库
    Dim sql As String = "insert into technologydept_onlinemackey set mainboardID='123456',test_time=Now()"
    Dim command As MysqLCommand = New MysqLCommand(sql,Connection)
    'Dim mydata As MysqLDataReader
    'mydata = command.ExecuteReaderEx
    'While mydata.Read
    ' If mydata.HasRows Then
    ' MsgBox(mydata(0).ToString)
    ' Else
    ' MsgBox("no")
    ' End If
    'End While
    command.ExecuteNonQuery()
    command.dispose()
    Connection.Close()
    MsgBox("OK")
Catch ex As Exception
    MsgBox(ex.Message)
End Try
