            FileStream fs = new FileStream(path,FileMode.Create);//创建文件流对象
            StreamWriter sw = new StreamWriter(fs);//创建写入器
            StringBuilder builder = new StringBuilder();//创建可变字符对象
            builder.AppendLine("<?xml version=\"1.0\" encoding=\"utf-8\"?>");//追加行
            builder.AppendLine("<Note>");
            builder.AppendLine("<Day year=\"{0}\" month =\"{1}\" day =\"{2}\">");

            builder.AppendLine("</Note>");
            string show = string.Format(builder.ToString(), txtYY.Text, txtMM.Text, txtDD.Text,txtTo.Text, txtFrom.Text, txtHeading.Text, txtMessage.Text );
            sw.Write(show);//格式字符串
            sw.Close();//关闭写入流
            fs.Close();//关闭文件流
            DialogResult result = MessageBox.Show("生成文件成功！","提示",MessageBoxButtons.OKCancel,MessageBoxIcon.Information);
            if (result==DialogResult.OK)
            {
                this.Close();//关闭当前的窗体
            }
        }
    }

}

程序演示

生成的Note.xml

<?xml version="1.0" encoding="utf-8"?>
<Note>
<Day year="2016" month ="2" day ="23">
<To>赵三儿</To>
<From>李四儿</From>
<Heading>吃饭</Heading>
<Message>饭热好了，我知道你的身体不太好，要趁热吃</Message>
