Visual basic 2010錯誤

Question

嘗試運行代碼時，我不斷收到有關fee.ToString（「C」）的錯誤。我一直得到的錯誤是'String'類型的值無法轉換爲'System.Windows.Forms.Textbox'。不知道我在做什麼錯我可以得到任何幫助將不勝感激。我的代碼如下。

Private Sub calcButton_Click(sender As Object, e As EventArgs) Handles calcButton.Click 

    Try 
     Dim bailInt As Integer 
     Dim collItem As String 

     Dim fee As Decimal = CDec(0.0) 

     'Convert input to values 
     bailInt = Integer.Parse(bailAmountTextBox.Text) 
     collItem = collateralTextBox.Text 

     'Calculate 10% fee on bail amount 
     fee = CDec(0.1 * bailInt) 

     'Display Messagebox with fee amount 
     amountDueTextBox = fee.ToString("C") 

    Catch ex As Exception 
     MessageBox.Show("Must be numeric data", "Bad Data", MessageBoxButtons.OK, MessageBoxIcon.Exclamation) 
     With bailAmountTextBox 
      .Focus() 
      .SelectAll() 
     End With 

    End Try 
End Sub 

Answer 1

amountDueTextBox.Text = fee.ToString("C")試試這個。你試圖將一個文本框分配給一個字符串。
