The log4net syntax for expanding environment variables is "${Variable}" e.g.
用于扩展环境变量的 log4net 语法是“${Variable}”，例如
<file value="${LOCALAPPDATA}\GojiSoft\GojiLog\log.txt" />

Resurrecting an old thread here, but I encountered the same issue and thought I'd share.
在这里复活一个旧线程，但我遇到了同样的问题，并认为我会分享。
${PROGRAMDATA}, as discussed in the comment thread of the other answer, didn't work for me (same as for OP). However, I saw a comment somewhere about it being case sensitive. Tried ${ProgramData} and sure enough, it worked fine.
${PROGRAMDATA}，正如在另一个答案的评论线程中所讨论的，对我不起作用（与 OP 相同）。但是，我在某处看到了关于区分大小写的评论。尝试了 ${ProgramData} 果然，它运行良好。
