keshen-msft opened a new issue, #41110: URL: https://github.com/apache/arrow/issues/41110
### Describe the bug, including details regarding any error messages, version, and platform. When input stream is empty, the reader throws exception when reading the schema, refer to https://github.com/apache/arrow/blob/cd607d00b9e3c5f2ac2a2e373ba7571fd75fc725/csharp/src/Apache.Arrow/Ipc/ArrowStreamReaderImplementation.cs#L157. Exception details: System.InvalidOperationException HResult=0x80131509 Message=Unexpectedly reached the end of the stream before a full buffer was read. Source=Apache.Arrow StackTrace: at Apache.Arrow.Ipc.ArrowStreamReaderImplementation.EnsureFullRead(Memory`1 buffer, Int32 bytesRead) in /arrow/csharp/src/Apache.Arrow/Ipc/ArrowStreamReaderImplementation.cs:line 276 at Apache.Arrow.Ipc.ArrowStreamReaderImplementation.ReadMessageLength(Boolean throwOnFullRead) in /arrow/csharp/src/Apache.Arrow/Ipc/ArrowStreamReaderImplementation.cs:line 238 at Apache.Arrow.Ipc.ArrowStreamReaderImplementation.ReadSchema() in /arrow/csharp/src/Apache.Arrow/Ipc/ArrowStreamReaderImplementation.cs:line 179 at Apache.Arrow.Ipc.ArrowStreamReaderImplementation.ReadRecordBatch() in /arrow/csharp/src/Apache.Arrow/Ipc/ArrowStreamReaderImplementation.cs:line 106 at Apache.Arrow.Ipc.ArrowStreamReaderImplementation.ReadNextRecordBatch() in /arrow/csharp/src/Apache.Arrow/Ipc/ArrowStreamReaderImplementation.cs:line 53 at Apache.Arrow.Ipc.ArrowStreamReader.ReadNextRecordBatch() in /arrow/csharp/src/Apache.Arrow/Ipc/ArrowStreamReader.cs:line 107 ... On the other hand, javascript handles such input. And C++ lib also handles it, refer to https://github.com/apache/arrow/blob/cd607d00b9e3c5f2ac2a2e373ba7571fd75fc725/cpp/src/arrow/ipc/reader.cc#L1109C7-L1111C10. The behavior in javascript and C++ is that null RecordBatch is returned. ### Component(s) C# -- This is an automated message from the Apache Git Service.
