Vb.net Visual basic 2010错误

在尝试运行代码时，我不断收到关于fee.ToString（“C”）的错误。我一直得到的错误是“String”类型的值无法转换为“System.Windows.Forms.Textbox”。我不知道我做错了什么，如果能得到任何帮助，我将不胜感激。我的代码如下

    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

amountDueTextBox.Text=fee.ToString（“C”）

试试这个。您正在尝试将文本框指定给字符串。

谢谢，真不敢相信我竟然错过了。
