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:UsersAdminDesktop";
            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:UsersAdminDesktop");
        /// richTextBox1.AppendText(s + "
");
        /// </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:UsersAdminDesktop";
            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:UsersAdminDesktop");
            richTextBox1.AppendText(s + "
");
        }
