本文实例讲述了C#使用Streamwriter打开文件的方法。分享给大家供大家参考。具体如下：

using System; using System.IO; public class KtoD1 { public static void Main() { string str; StreamWriter fstr_out; // Open the file directly using StreamWriter. try { fstr_out = new StreamWriter("test.txt"); } catch(IOException exc) { Console.WriteLine(exc.Message + "Cannot open file."); return ; } Console.WriteLine("Enter text ('stop' to quit)."); do { Console.Write(": "); str = Console.ReadLine(); if(str != "stop") { str = str + "rn"; // add newline try { fstr_out.Write(str); } catch(IOException exc) { Console.WriteLine(exc.Message + "File Error"); return ; } } } while(str != "stop"); fstr_out.Close(); } }

希望本文所述对大家的C#程序设计有所帮助。
