MySQL在VB.net中使用列表选择带条件的查询

Imports MySql.Data.MySqlClient

Public Class Form1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim connectionString As String = "server=服务器IP地址;port=端口号;database=数据库名称;uid=用户名;pwd=密码;"
        Dim connection As New MySqlConnection(connectionString)
        Dim command As New MySqlCommand("SELECT 列1, 列2 FROM 表名 WHERE 条件", connection)

        connection.Open()

        Dim reader As MySqlDataReader = command.ExecuteReader()
        While reader.Read()
            Dim column1Value As String = reader("列1").ToString()
            Dim column2Value As String = reader("列2").ToString()

            ' 处理查询结果
            ' ...

        End While

        reader.Close()
        connection.Close()
    End Sub
End Class
