C＃怎么做才能让办公室在使用Word的拼写检查时没有开始

Question

我在我的应用中使用Microsoft Word来使用拼写检查对话框。每当您使用拼写检查时，Office都会打开。有没有办法阻止它？

这是我的代码：

Word.Application app = new Word.Application();

int errors = 0;
if (richTextBox1.Text.Length > 0) {
    app.Visible = false;
    this.BringToFront();

    // Setting these variables is comparable to passing null to the function.
    // This is necessary because the C# null cannot be passed by reference.
    object template = Missing.Value;
    object newTemplate = Missing.Value;
    object documentType = Missing.Value;
    object visible = true;

    Word._Document doc1 = app.Documents.Add(ref template, ref newTemplate, ref documentType, ref visible);
    doc1.Words.First.InsertBefore(richTextBox1.Text);
    Word.ProofreadingErrors spellErrorsColl = doc1.SpellingErrors;
    errors = spellErrorsColl.Count;

    object optional = Missing.Value;

    doc1.CheckSpelling(
        ref optional, ref optional, ref optional, ref optional, ref optional, ref optional,
        ref optional, ref optional, ref optional, ref optional, ref optional, ref optional);
    object first = 0;
    object last = doc1.Characters.Count - 1;
    richTextBox1.Text = doc1.Range(ref first, ref last).Text;
}

object saveChanges = false;
object originalFormat = Missing.Value;
object routeDocument = Missing.Value;

app.Quit(ref saveChanges, ref originalFormat, ref routeDocument);
