为什么C＃中的WriteLine会更改文本文件中的格式？

Question

因此，我正在编写一个应用程序，没有任何问题，我正在让Streamwriter使用WriteLine编写新行。 但是，当我进入某个文本框时，它会自动开始缩进。 请参见下面的图片和代码：

这在保存按钮下

        SaveFileDialog sfd = new SaveFileDialog();
        sfd.InitialDirectory = @"C:\DR\Desktop\4-22-18";
        sfd.RestoreDirectory = true;
        sfd.FileName = "G-12";
        sfd.Filter = "txt files(*.txt)|*.txt| Word Files | *.doc";

        if (sfd.ShowDialog()==DialogResult.OK)
        {
            Stream fileStream = sfd.OpenFile();
            StreamWriter sw = new StreamWriter(fileStream);
            sw.WriteLine(lblDate.Text);
            sw.WriteLine(lblTime.Text);
            sw.WriteLine("\r");
            sw.WriteLine("G-12"+"\t"+ lblNotes.Text + " " + txtNotes.Text);
            sw.WriteLine("==========================================");
            sw.WriteLine(lblSG.Text+" "+ nmSG.Text);
            sw.WriteLine("==========================================");
            sw.WriteLine(lblTinWeight.Text + "  " + nmTinWeight.Text);
            sw.WriteLine(lblKIO3.Text + " "+ nmKIO3Volume.Text);
            sw.WriteLine(lblKIO3N.Text + nmKIO3N.Text);
            sw.WriteLine(lblTinPercentage.Text + " "+ lblTinPercent.Text);
            sw.WriteLine(lblTinGram.Text + lblTinGrams.Text);
            sw.WriteLine("==========================================");
            sw.WriteLine(lblNeutWeight.Text+nmNeutWeight.Text);
            sw.WriteLine(lblNeutVolume.Text+nmNaOHVolume.Text);
            sw.WriteLine(lblNeutNormality.Text + nmNaOHNormality.Text);
            sw.Close();
        }

文本框包含一个空格。 通过在调试器中查看lblTinWeight.Text的值（或不确定的其他文本框）来验证这一点。
