.net教程：c#中对文件的操作小结
1、建立一个文本文件
public class fileclass
{
public static void main()
{
writetofile();
}
static void writetofile()
{
streamwriter sw;
sw=file.createtext("c:\mytextfile.txt");
sw.writeline("god is greatest of them all");
sw.writeline("this is second line");
sw.close();
console.writeline("file created sucacessfully");
}
}
2、读文件
public class fileclass
{
public static void main()
{
readfromfile("c:\mytextfile.txt");
}
static void readfromfile(string filename)
{
streamreader sr;
string s;
sr=file.opentext(filename);
s=sr.readline();
while(s!=null)
{
console.writeline(s);
s=sr.readline();
}
sr.close();
}
}
3、追加操作
public class fileclass
{
public static void main()
{
appendtofile();
}
static void appendtofile()
{
streamwriter sw;
sw=file.appendtext("c:\mytextfile.txt");
sw.writeline("this line is appended");
sw.close();
console.writeline("text appended successfully");
}
}
