'save richtextbox to file C#

I am having trouble saving from richtextbox to .txt file

here is the code:

if (richTextBox1.Text != String.Empty)
            {
                string dir = @"c:\\logs\\" + DateTime.Today.ToString("dd_MMM_yy");
                string path = @"c:\\logs\\" + DateTime.Today.ToString("dd_MMM_yy") + "\\" + DateTime.Now.ToString("HH.mm.ss") + ".txt";
                if (!Directory.Exists(dir))
                {
                    Directory.CreateDirectory(dir);
                }

                if (!File.Exists(path))
                {
                    File.Create(path);
                    richTextBox1.SaveFile(path, RichTextBoxStreamType.RichText);
                }

            }
            else
                MessageBox.Show("ERROR");

where I am going wrong ?! It says it cannot access the file because it is being used by another process... Any help would be welcome

Thanks, dnisko

Solution 1:[1]

you can avoid create file line because SaveFile will create file for you.

File.Create will return open stream for the file, you need to close it before access again. Do as below If you need to use create file anyway 

using(File.Create(path));
richTextBox1.SaveFile(path, RichTextBoxStreamType.RichText);

Solution 2:[2]

File.Create returns the Stream of the file created.

As long as you do not dispose it, it will keep the file open

You can also use the Stream to directly write to the file. Using the using statement helps getting around any allocation issues.

        using (FileStream fs = File.Create(path))
        {
            Byte[] info = new UTF8Encoding(true).GetBytes("This is some text in the file.");
            // Add some information to the file.
            fs.Write(info, 0, info.Length);
        }

 richTextBox1.SaveFile(saveFile1.FileName, RichTextBoxStreamType.PlainText);

Solution 4:[4]

to save the file

private void btnSave_Click(object sender , EventArgs e)
{   
     string  _Path=@"C:\temp\Untitled.txt";
      if (!File.Exists(_Path))
        {
            StreamWriter SW = new StreamWriter(_Path);
            SW.WriteLine(richTextBox1.Text);
            SW.Close();
        }
        else if (File.Exists(_Path))
        {
            MessageBox.Show("This File is Exists");
            SaveFileDialog SFD = new SaveFileDialog();
            SFD.FileName = "";
            SFD.AddExtension = true;
            SFD.DefaultExt = ".txt";
            DialogResult result= SFD.ShowDialog();
            if(string.IsNullOrEmpty( SFD.FileName))
            {
                return;
            }
            else if(result==DialogResult.OK)
            {
                StreamWriter SW = new StreamWriter(SFD.FileName);
                SW.WriteLine(richTextBox1.Text);
                SW.Close();
            }
}
