如何将数据从RichTextBox保存到文件或从文件中加载

Question

我有Richtextbox可以输入具有多种字体名称，颜色，背景颜色和大小的文本。

我想保存它并使用相同的设置加载它。

Private Sub SaveAsToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveAsToolStripMenuItem.Click 
    SaveFileDialog1.Filter = "TextFile (*.txt;*.rtf)|*.txt;*.rtf|Batch File (*.bat)|*.bat|All Files (*.*)|*.*" 
    SaveFileDialog1.FileName = "Untitled" 
    If SaveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then 
     Dim a() As String = SaveFileDialog1.FileName.Split("\") 
     Dim sw As New StreamWriter(SaveFileDialog1.FileName) 
     sw.Write(RichTextBox1.Text) 
     My.Settings.Save() 
     sw.Close() 
    End If 
End Sub 

Answer 1

Use the RichTextBox.SaveFile Method

Answer 2

您可以使用此代码阅读：

RichTextbox1.text = System.IO.File.ReadAllText(openfilepath) 

这写：

System.IO.File.WriteAllText(Savefiledialog1.FileName, Richtextbox1.text) 

希望这将有助于。
