开时始，得到的中文文件中的字符是乱码的，鸟符号看的头晕。于是就细究streamreader读取的编码格式，默认的编码是ascii，单字节的，就尝试utf8，乱码；尝试gb2312，OK！
可另一个问题又出现了，得到的两个文件的行数都不到1500行，尝试N次还是不行，很郁闷。google了下，看到try catch，就想到释放缓冲区，结果很HAPPY！
private static void FnFileProcess()
{
StreamReader reader = new StreamReader(@"d:\1500.txt", Encoding.GetEncoding("GB2312"));
StreamWriter writerEn = new StreamWriter(@"d:\English.txt", false, Encoding.UTF8, 1024);
StreamWriter writerCh = new StreamWriter(@"d:\Chinese.txt", false, Encoding.UTF8, 1024);
try
{
int i = 1;
for (String line = reader.ReadLine(); line != null; line = reader.ReadLine())
{
if (i % 2 == 1)
{
writerEn.WriteLine(line);
}
else
{
writerCh.WriteLine(line);
}
i++;
}
Console.WriteLine(i + "\tOK");
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
finally
{
//不清空缓冲区，得到的文件总是少几十行
writerEn.Flush();
writerCh.Flush();
}
}
C#读取中文字符及清空缓冲区的实现代码
