本文實例講述了C#使用Streamwriter打開文件的方法。分享給大家供大家參考。具體如下：
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 + "/r/n"; // add newline try { fstr_out.Write(str); } catch(IOException exc) { Console.WriteLine(exc.Message + "File Error"); return ; } } } while(str != "stop"); fstr_out.Close(); }}希望本文所述對大家的C#程序設計有所幫助。
