我正在DataAvailable
循环中阅读NetworkStream
的所有while
,并且在每个周期中我都在阅读具有chunk
特定尺寸的可用数据:
TcpClient client = new TcpClient("server address", 23);
NetworkStream stream = client.GetStream();
byte[] data = new byte[2048]; // read in chunks of 2KB
int bytesRead;
string output = "";
do
{
bytesRead = stream.Read(data, 0, data.Length);
output += System.Text.Encoding.ASCII.GetString(data, 0, data.Length);
} while (stream.DataAvailable);
return output;
问题出在输出中我从收到的字节中间得到一些随机文本,我的意思是类似的东西:
1 A
2 B
3 C
4 D
5 E
6 F
7 G
8 H
9 I
10 J //here my output must finish but random bytes from middle append to the end:
3 C //repetitive bytes
4 D //repetitive bytes
5 E //repetitive bytes
令我困惑的是,如果我将块大小从2048
增加到3072
,则不会发生此问题。
我还在每个周期跟踪TcpClient.Available
一个断点:
First cycle -> 4495
Second cycle -> 2447
Third cycle -> 399
Forth cycle -> 0
答案 0 :(得分:3)
我原以为:
output += System.Text.Encoding.ASCII.GetString(data, 0, data.Length);
应该是这样的:
output += System.Text.Encoding.ASCII.GetString(data, 0, bytesRead);
确保只有在特定场合读取的数据才会包含在输出中。
