如何在Visual Studio中使用RichTextBox使documents.docx只讀？

Question

下面是我的代碼，當它調試時，文檔將在Rich TextBox中打開，但它可以編輯，因此我需要它爲ReadOnly。你能幫我解決嗎？

void ImportWord() 
{ 
    Microsoft.Office.Interop.Word.Application wordObject = new Microsoft.Office.Interop.Word.Application(); 
    object File = @"C:\Users\czu_ecu\Desktop\OAG-WORK\Management_Letter_Template1.docx" ; //this is the path 
    object nullobject = System.Reflection.Missing.Value; Microsoft.Office.Interop.Word.Application wordobject = new Microsoft.Office.Interop.Word.Application(); 
    wordobject.DisplayAlerts = Microsoft.Office.Interop.Word.WdAlertLevel.wdAlertsNone; Microsoft.Office.Interop.Word._Document docs = wordObject.Documents.Open(ref File, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject); docs.ActiveWindow.Selection.WholeStory(); 
    docs.ActiveWindow.Selection.Copy(); 
    this.richTextBox2.Paste(); 
    docs.Close(ref nullobject, ref nullobject, ref nullobject); 
    wordobject.Quit(ref nullobject,ref nullobject, ref nullobject); 
} 

private void btnTemML_Click(object sender, EventArgs e) //Handles the actions of the template button 
{ 
    btnAdd_Finding.Visible = false; 
    listView2.Visible = false; 
    label8.Visible = false; 
    richTextBox1.Visible = false; 
    listView1.Visible = false; 
    listView3.Visible = false; 
    richTextBox2.Visible = true; 

    ImportWord(); 

    listView1.Items.Clear(); 
}

您可以嘗試下面的代碼。

richTextBox2.Visible = true; 
richTextBox2.IsReadOnly = true;
