fluent-assertions - 如何比较两个 MemoryStream 与 FluentAssertions

Question

使用 FluentAssertion 3.1.229 , 你如何比较两个不同的 MemoryStream 的内容？

编写 actualStream.Should().Be(expectedStream); 会产生以下错误:

System.IO.MemoryStream
{
   CanRead = True
   CanSeek = True
   CanTimeout = False
   CanWrite = True
   Capacity = 8
   Length = 8
   Position = 0
   ReadTimeout = "[Property 'ReadTimeout' threw an exception: 'Exception has been thrown by the target of an invocation.']"
   WriteTimeout = "[Property 'WriteTimeout' threw an exception: 'Exception has been thrown by the target of an invocation.']"
}, but found 

System.IO.MemoryStream
{
   CanRead = True
   CanSeek = True
   CanTimeout = False
   CanWrite = True
   Capacity = 8
   Length = 8
   Position = 0
   ReadTimeout = "[Property 'ReadTimeout' threw an exception: 'Exception has been thrown by the target of an invocation.']"
   WriteTimeout = "[Property 'WriteTimeout' threw an exception: 'Exception has been thrown by the target of an invocation.']"
}.

是的，我可以使用 NUnit Assert.That(actualStream, Is.EqualTo(expectedStream)); 但是 FluentAssertions 可以吗？

谢谢。

也许这对你有用？

actualStream.ToArray().Should().Be(expectedStream.ToArray());
