Question

我的用意是将“条码”写到档案中。法典如下:

byte[] stream = { 10, 20, 30, 40, 60 };

for (int i = 0; i < 2; i++)
{
    FileStream aCmdFileStream = new FileStream(@"c:inarydata.txt", FileMode.Append, FileAccess.Write, FileShare.None);
    StreamWriter aStreamWriter = new StreamWriter(aCmdFileStream);

    for (int ii = 0; ii < stream.Length; ii++)
    {
        aStreamWriter.Write(stream[ii]);
        aStreamWriter.WriteLine(); 
        aStreamWriter.BaseStream.Write(stream,0,stream.Length);
    }

    aStreamWriter.Close();
}

该法典的输出

(<

(<
(<10
20
30
40
60

(<

(<
(<
(<10
20
30

60

When StreamWriter.Write() is used it dumps the values which are stored in array. But StreamWriter.BaseStream.Write(byte[],int offset, int length), the values are totally different. What is the reason for this?

Answer 1

This is because StreamWriter is a TextWriter and converts the bytes to Text (string representation).

并且使用<代码>BaseStream.Write(byte [] data, ......>,直接写出不作任何改动的tes。

但是,你正在使用两套方法,我猜测,有些夸张也正在发生。请注意,你应使用一种或另一种,而不是两者。
