How to save a file without using the SaveDialog Box?

Hello,

So I have a program which basically takes a lot of reading and everytime we take a reading we want to save the file. Now the problem is I am using the Savedialog and calling the ShowDialog function. But what I am really looking for is it should just save the file automatically and not show the SaveDialog Box?

the code for Saving is as follows:

 private bool SaveMeasureDialog()
        {SaveFileDialog saveFileDialog = new SaveFileDialog();
            saveFileDialog.InitialDirectory = this.defaultRootPath;
            saveFileDialog.Filter = "Measured files (*.vlg)|*.vlg|All files (*.*)|*.*";
            saveFileDialog.FilterIndex = 1;
            saveFileDialog.DefaultExt = "vlg";
            saveFileDialog.RestoreDirectory = true;
            saveFileDialog.OverwritePrompt = true;
            if (!string.IsNullOrEmpty(this.filePath))
            {
                FileInfo fileInfo = new FileInfo(this.filePath);
                saveFileDialog.InitialDirectory = this.defaultRootPath;   
                 saveFileDialog.FileName = "Measure1";

            }
            bool flag = saveFileDialog.ShowDialog() == DialogResult.OK;
            if (flag)
            {
                
                this.SaveMeasure(saveFileDialog.FileName);

            }
            return !flag;
}


public void SaveMeasure(string fp)
        {
            FileStream fileStream = File.Create(fp);
            FileStream fileStream1 = fileStream;
            if (fileStream != null)
            {
                if (this.filePath != fp)
                {
                    this.msr.IdNumber = Guid.NewGuid();
                }
                MeasureXml.SaveMeasure(fileStream1, this.measure, this.RootPathDb);
                this.filePath = fp;
                this.changed = false;
                this.OnFileInfoChanged(EventArgs.Empty);
            }
        }

This is the part of the code where it reads the file and save the measurement too in the file. Now what I am really looking for is to eliminate the SaveFileDialog.ShowDialog part and instead just save the file cos I no what path I want to save it (by default it will be the rootPath ) and also the name is pretty much always "Measure".

Thanks in advance for any suggestions or solutions!!
