C#winform向Txt文件传值,不重复录入且不清空
private void textLog_TextChanged(object sender, EventArgs e) { FileStream fs = new FileStream(@"C:\\文件导入记录日志.txt", FileMode.Open); StreamReader Reader = new StreamReader(fs); string strLine = Reader.ReadLine(); while (strLine!=null && strLine!="") { strLine = Reader.ReadLine(); } StreamWriter sw = new StreamWriter(fs); sw.WriteLine(strLine+textLog.Text); sw.Flush(); sw.Close(); fs.Close(); }
