像你这样的代码片段对我有用，我无法重现提到的错误消息。

Public Class Form1
  Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    TextBox1.Font = New Font(TextBox1.Font, FontStyle.Bold)
  End Sub

  Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    TextBox1.Text = "StackOverflow"
  End Sub
End Class
