C# 创建新RTF文件

 

这个和WINDOWS创建RTF文件一样

 

public void CreateRtfFile(string RtfFileName)

   {

            RichTextBox richTextBox1 = new RichTextBox();

            richTextBox1.SaveFile(RtfFileName);

   }

 

private void button1_Click(object sender, EventArgs e)

   {

            string Dir = @"C:\Users\Admin\Desktop\";

            string FileTitle = "新建 RTF 文档";

            string FileExt = ".rtf";



            string s1 = Dir + FileTitle + FileExt;

            int j = 2;

            if (System.IO.File.Exists(s1))

            {

                string s = String.Format("{0}{1}({2}){3}",Dir,FileTitle,j,FileExt);

                while (System.IO.File.Exists(s))

                {

                    j++;

                    s = String.Format("{0}{1}({2}){3}", Dir, FileTitle, j, FileExt);

                }

                if (!System.IO.File.Exists(s))

                {

                    CreateRtfFile(s);

                }

            }

            else

                  CreateRtfFile(s1);

            

     }

 

创建一个文件并返回这个文件名称

        /// <summary>

        /// 新建 RTF 文档 新建 RTF 文档(2) 新建 RTF 文档(3)...

        /// string s = CreateRtfFile2(@"C:\Users\Admin\Desktop\");

        /// richTextBox1.AppendText(s + "\r\n");

        /// </summary>

        /// <param name="path"></param>

        /// <returns>返回当前创建的文件名 如 “新建 RTF 文档” </returns>

        public string CreateRtfFile2(string path)

        {

            //string path = @"C:\Users\Admin\Desktop\";

            string FileTitle = "新建 RTF 文档";

            string FileExt = ".rtf";

            string Result = FileTitle;



            string s1 = path + FileTitle + FileExt;

          

            int j = 2;

            if (System.IO.File.Exists(s1))

            {

                string s = String.Format("{0}{1}({2}){3}", path, FileTitle, j, FileExt);

               

                while (System.IO.File.Exists(s))

                {

                    j++;

                    s = String.Format("{0}{1}({2}){3}", path, FileTitle, j, FileExt);

                }

                if (!System.IO.File.Exists(s))

                {

                    CreateRtfFile(s);

                     FileTitle = System.IO.Path.GetFileNameWithoutExtension(s);

                }

            }

            else

                CreateRtfFile(s1);

            return FileTitle;

        }

使用

        private void button1_Click(object sender, EventArgs e)

        {

            string s = CreateRtfFile2(@"C:\Users\Admin\Desktop\");

            richTextBox1.AppendText(s + "\r\n");

        }
