使用Environment.NewLine

 tw1.WriteLine(Environment.NewLine); 

使用\ r \ n常量

 tw1.WriteLine(" );  pre> 

您完全不能使用任何参数:

tw1.WriteLine();

Hello to all possible help I want to code to add a new line of the program

TextReader tr = new StreamReader("c:\\date.txt");
            
            
            // read a line of text
            String s1 = tr.ReadLine();
            // close the stream
            
            //String s1 = "One Two Three Four";
            char[] seps = {'' ''};
            String[] values = s1.Split(seps);
            TextWriter tw1 = new StreamWriter("d:\\bdate1.txt");
            

            // write a line of text to the file
            
            // close the stream
            for (int i = 0; i < values.Length; i++)
            {
                
                    tw1.WriteLine(values[i]);

                
            }          
            tr.Close();
            tw1.Close();

Using Environment.NewLine

tw1.WriteLine(Environment.NewLine);

Using \r\n constant

tw1.WriteLine("\r\n");

You may not use any arguments at all:

tw1.WriteLine();
