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 + "\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();
}
}
希望本文所述对大家的C#程序设计有所帮助。
