如何在vb.net中使用嵌入式资源正确使用名称空间？

Imports System.IO
Imports System.Drawing
Imports System.Windows.Forms

Public Class Form1
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        ' 加载嵌入式图像资源并将其设置为窗体的背景图像
        Dim img As Image = My.Resources.MyImage
        Me.BackgroundImage = img

        ' 从嵌入式文本文件中读取内容并将其显示在窗体上
        Dim sr As StreamReader = New StreamReader(My.Resources.MyTextFile.Stream)
        Dim text As String = sr.ReadToEnd()
        sr.Close()
        Me.Text = text
    End Sub
End Class
