我在从 C# 中的进程 StandardOutput 读取数据时遇到问题。这是我所拥有的:
var hdd = new System.Diagnostics.Process();
hdd.StartInfo.FileName = "C:\\Program Files\\Java\\jre7\\bin\\java.exe";
hdd.StartInfo.Arguments = "-jar minecraft.jar";
hdd.StartInfo.RedirectStandardOutput = true;
hdd.StartInfo.UseShellExecute = false;
hdd.Start();
while (!hdd.StandardOutput.EndOfStream)
{
string data = hdd.StandardOutput.ReadLine();
Console.WriteLine(">> " + data);
}
在这里,我有第二个代码,用 Python 编写:
cmd = '"C:\\Program Files\\Java\\jre7\\bin\\java.exe" -jar minecraft.jar'
import subprocess
p = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE)
while True:
line = p.stdout.readline()
print '>> ', line.strip()
if line == '' and p.poll() != None:
break
问题是,这两个代码都在工作,但在 python 中,脚本打印的信息是 C# 的两倍。
C# 输出:
>> 229 recipes
>> 27 achievements
>>
>> Starting up SoundSystem...
>> Initializing LWJGL OpenAL
>> (The LWJGL binding of OpenAL. For more information, see http://www.lwjgl.org)
>> OpenAL initialized.
Python的输出:
>> 229 recipes
>> 27 achievements

所以我们可以清楚地看到,C#中缺少一些信息。具体来说,pythons输出中没有“>>”的行。有什么办法,我可以在 C# 中捕捉那些缺失的行吗?
