以前有人解决过这个问题吗？谢谢您的支持。
我喜欢从定义的连接参数构建连接字符串 - 无论是否使用专用构建器：
Dim (or Const) Server As String = "MyServer"
Dim (or Const) Port As UInteger= 3456
Dim (or Const) Database As String = "MyDatabase"
Dim (or Const) UserId As String = "MyUser"
Dim (or Const) Password As String = "MyPassword"
Dim mySql As New MySql.Data.MySqlClient.MySqlConnectionStringBuilder() With {
.Server = Server,
.Port = Port,
.Database = Database,
.UserId = UserId,
.Password = Password
}
MySQL String Builder ( mySql.ConnectionString) 的结果：
server=MyServer;port=3456;database=MyDatabase;user id=MyUser;password=MyPassword
或者自己动手：
Dim myConn As String = $"Server={Server};Port={Port};Database={Database};Uid={UserId};Pwd={Password}"
（注意UserId和Password 的备用参数命名。）
