EndOfStreamException 与简单的 BinaryWriter 和 BinaryReader
EndOfStreamException with simple BinaryWriter and BinaryReader
我正在使用以下代码:
var fileStream = new MemoryStream();
var binaryWriter = new BinaryWriter(fileStream);
var binaryReader = new BinaryReader(fileStream);
binaryWriter.Write("Hello");
var msg = binaryReader.ReadString();
但是我遇到了以下异常:
System.IO.EndOfStreamException: Unable to read beyond the end of the stream.
读取前,binaryReader.BaseStream.Length
大于0,然而binaryReader.PeekChar()
returns -1.
我做错了什么?
写入流后,流的位置将是您写入的内容的长度。
为了在写入后直接从中读取,您必须重置流的位置:
binaryWriter.Write("Hello");
binaryWriter.BaseStream.Position = 0;
var msg = binaryReader.ReadString();
将导致写入流的原始 "Hello" 分配给 msg
。
