关于RichTextBox 及 RTF格式文件的保存

C# Visual Studio 2005中RichTextBox保存文件为rtf格式

SaveFileDialog saveFile1 = new SaveFileDialog();
// Initialize the SaveFileDialog to specify the RTF extention for the file.
saveFile1.DefaultExt = "*.rtf";
saveFile1.Filter = "RTF Files|*.rtf";

// Determine whether the user selected a file name from the saveFileDialog.
if (saveFile1.ShowDialog() == System.Windows.Forms.DialogResult.OK &&
               saveFile1.FileName.Length > 0)
{
    // Save the contents of the RichTextBox into the file.
            richTextBox1.SaveFile(saveFile1.FileName);
}

RichTextBox文本保存为WORD格式：

private void button1_Click(object sender, System.EventArgs e)

{//保存为WORD文件

if(this.richTextBox1.Text=="")

return;

if(this.saveFileDialog1.ShowDialog()==DialogResult.Cancel)

return;

string FileName=this.saveFileDialog1.FileName;

if(FileName.Length<1)

return;

FileName+=".doc";

try

{

Word.ApplicationClass MyWord=new Word.ApplicationClass();

Word.Document MyDoc;

Object Nothing=System.Reflection.Missing.Value;

MyDoc=MyWord.Documents.Add(ref Nothing,ref Nothing,ref Nothing,ref Nothing);

MyDoc.Paragraphs.Last.Range.Text=this.richTextBox1.Text;

object MyFileName=FileName;

//将WordDoc文档对象的内容保存为DOC文档

// MyDoc.SaveAs(ref MyFileName,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing);

//关闭WordDoc文档对象

MyDoc.Close(ref Nothing, ref Nothing, ref Nothing);

//关闭WordApp组件对象

MyWord.Quit(ref Nothing, ref Nothing, ref Nothing);

MessageBox.Show("WORD文件保存成功","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
