我已经阅读了所有的问题和答案从以前的职位，但不适合我的问题
问题：我想显示从db（mysql）到datagrid的数据，但问题是 MySqlDataReader 无法识别

SelectCommand

Fill 

Update

作为 MySqlDataReader 我遵循教程中完全相同的代码编写方法，为什么会出现这个问题？？
下面我附上了我的代码。我希望有人能帮我。

Imports MySql.Data.MySqlClient

Public Class AdminAddItem
Dim MysqlConnection As MySqlConnection
Dim FoodCommand As MySqlCommand
Dim DataFoodRead As MySqlDataReader
Dim dbDataSetFood As New DataTable

Private Sub btnLoadFood_Click(sender As Object, e As EventArgs) Handles btnLoadFood.Click
    'declare new connection
    MysqlConnection = New MySqlConnection

    'prepare connection string
    MysqlConnection.ConnectionString =
        "server = localhost; userid = root; password = 1234 ; database = kedaikopimamba_db"

    Dim bSource As New BindingSource

    Try
        MysqlConnection.Open()

        Dim query As String
        query = "select * from kedaikopimamba_db.foodtable"

        FoodCommand.Connection = MysqlConnection
        FoodCommand.CommandText = query

       DataFoodRead.SelectCommand = FoodCommand
        DataFoodRead.Fill(dbDataSetFood)
        bSource.DataSource = dbDataSetFood
        dgDisplayItem.DataSource = bSource
        DataFoodRead.Update(dbDataSetFood)

        MysqlConnection.Close()
    Catch ex As MySqlException
        MessageBox.Show(ex.Message)
    Finally
        MysqlConnection.Dispose()
    End Try

End Sub
End Class
