How to create RTF from plain text (or string) in C#?

Question

Could anyone please help me to create RTF from string in C#?

I save all the formats (bold, italic, etc) in a customized class.

I know i'm NECRO an old question but, anyways, here is my apport:

//This Instances a new RichTextBox Control and uses it so save the Text
private void Save_RTF_file(string pFilePath, string pRTFText)
{
    try
    {
        using (RichTextBox RTB = new RichTextBox())
        {
            RTB.Rtf = pRTFText;
            RTB.SaveFile(pFilePath, RichTextBoxStreamType.RichText);
        } 
    }
    catch (Exception ex)
    {
        throw ex;
    }
}

Now you pass a file_path and the RTF formatted Text:

//This is a simple 1 line 'Hello World' RTF text
string RTF = @"{\rtf1\ansi\ansicpg1252\deff0\nouicompat\deflang14346{\fonttbl{\f0\fnil\fcharset0 Calibri;}} {\*\generator Riched20 10.0.10586}\viewkind4\uc1 \pard\sa200\sl276\slmult1\f0\fs22\lang10 Hello World.\par }";

Save_RTF_file(@"C:\temp\my_rtf_file.rtf"), RTF);

Hope it helps.
