我可能是不正確有關這一點，但線下看起來很奇怪...

Dim path As String = "& TextBox2.text &" 

這將創建一個名爲path具有字符串值：& TextBox2.text & ...

然後你在OleDbConnection使用path字符串：

MyConnection = New System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;") 

在線之上你試圖連接到一個名爲DataSource「& TextBox2.text & ... ???

我從代碼猜測表格TextBox2.Text上的文本框包含要打開的Excel文件的完整路徑。如果是這種情況，那麼簡單地改變變量字符串path象下面這樣：

Dim path As String = TextBox2.Text 

只是一個想法。
