How can i Rewrite File instead of appending using StreamWriter and file stream

I want to rewrite text file using StreamWriter. but when StreamWriter uses stream (like following code), the text will append to file.

StreamWriter sw = new StreamWriter(fstream);
sw.Write(text);
sw.Close();

i must use Stream in code because of that file share limitation

FileMode.Create ll create a new file. If the file excists, it ll show exception. Use FileMode.Truncate. 

 string txt="your text";
    using (FileStream fs = new FileStream(@"C:\Users\rajesh.kumar\Desktop\test123.txt", FileMode.Truncate))
    {
        using (StreamWriter writer = new StreamWriter(fs))
        {
            writer.Write("txt");
        }
    }

If you use file stream, set FileMode:

using (FileStream fs = new FileStream(fileName, FileMode.CreateNew))
{
    using (StreamWriter writer = new StreamWriter(fs))
    {
        writer.Write(textToAdd);
    }
}
