创建的新文本文件中的
输出是hello world



但是我想要你好在新的一行和世界......怎么样？ help

解决方案

尝试添加

 Environment.NewLine 

添加新行。

  for （ int  i =  0 ; i <  richTextBox1。 Lines.Length; i ++）
 {
 sw.WriteLine（richTextBox1.Lines [i]）; 
} 

试试这个！

 sw.WriteLine（richTextBox1.Text + < span class =code-string>  \ n）; 

private void file_write()
        {
            string path = "C:\\Users\\Techsoft\\Desktop\\textbox\\text2";           
            string ext = ".txt";
            string fname = path + ext;
            
            
            FileInfo file1 = new FileInfo(fname);
            StreamWriter sw = file1.CreateText();
            sw.WriteLine(richTextBox1.Text);

            sw.Close();
        }

        private void file_read()
        {
            string path = "C:\\Users\\Techsoft\\Desktop\\textbox\\text";           
            string name = richTextBox1.Text;
            string ext = ".txt";
            string fname = path + name + ext;
            string readcontent;

            FileInfo file1 = new FileInfo(fname);

            StreamReader sr = new StreamReader(fname);
            readcontent = sr.ReadToEnd(); 	    
            sr.Close();
            richTextBox1.Text = readcontent;             
        }
        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {
            file_read();

        }

        private void button2_Click(object sender, EventArgs e)
        {
            file_write();
        } 

output in new textfile created is "hello world"

but i want hello in one line and world in new line.. how? help

解决方案

try to add

Environment.NewLine

to add new line.

try this.

for (int i = 0; i < richTextBox1.Lines.Length; i++)
{
     sw.WriteLine(richTextBox1.Lines[i]);
}

Try this!

sw.WriteLine(richTextBox1.Text+"\n");
