我有这个场景:
DownloadLibrary.GetData(Stream targetStream);
SaveLibrary.WriteData(Stream sourceStream);
我想将 targetStream 收集的数据发送到 sourceStream。我想出了一些解决方案,但我找不到直接连接这些流的方法。
我想要实现的是将数据从 targetStream 发送到 sourceStream 而不先缓冲 targetStream。
如何做呢?
提前致谢。
最佳答案
Stream
中有内置支持(来自 .Net 4.0),用于通过 CopyTo
将一个流复制到另一个流,例如:
stream1.CopyTo(stream2)
例子:
[Test]
public void test()
{
string inString = "bling";
byte[] inBuffer = Encoding.ASCII.GetBytes(inString);
Stream stream1 = new MemoryStream(inBuffer);
Stream stream2 = new MemoryStream();
//Copy stream 1 to stream 2
stream1.CopyTo(stream2);
byte[] outBuffer = new byte[inBuffer.Length];
stream2.Position = 0;
stream2.Read(outBuffer, 0, outBuffer.Length);
string outString = Encoding.ASCII.GetString(outBuffer);
Assert.AreEqual(inString, outString, "inString equals outString.");
}
