题

如何将其写入磁盘以查看它是哪种文件？

回答

(由Esteban编辑)

./TabularATest1.xlsx' asFileReference writeStreamDo: [ :stream | stream binary; nextPutAll: self testExcelSheet ]

Answer 1

最简单的方法是这样的:

'./file.bin' asFileReference writeStreamDo: [ :stream | 
    stream 
        binary; 
        nextPutAll: #[1 2 3 4 5 6 7 8 9 0] ]

所以诀窍就是告诉流"是一个二进制文件":)
