Vb.net 找不到 Visual Studio 2022 关键字“address”

问：

请有人指导我在哪里可以识别错误正在与之通信的地址。每当我运行项目时，在连接数据库后。出现以下错误：

Private Sub Main_Menu_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        conn = New MySqlConnection
        conn.ConnectionString = "server=(LocalDb)\cedriclocaldb;username=cedricoruga;password=123456;database=consignmentdatabase"

        Try
            conn.Open()
            sql = "select * from consignment_tbl_ced"
            command.Connection = conn
            command.CommandText = sql
            myadapter.SelectCommand = command
            myadapter.Fill(mydata)
            DataGridView1.DataSource = mydata
            conn.Close()
            MessageBox.Show("Connection to database is successful!", "Testing Connection to MySQL Database")
            conn.Close()
        Catch ex As Exception
            MsgBox("Error:" & Err.Description)
        Finally

            conn.Dispose()

        End Try
    End Sub
