使用 System.Uri 附加多个段 [英] Appending multiple segments with System.Uri
问题描述
var baseUri = new Uri("http://localhost/");
var uri1 = new Uri(baseUri, "1");
var uri2 = new Uri(uri1, "2");
出乎意料的是,uri2
是 http://localhost/2.我将如何附加到 uri1
所以它是 http://localhost/1/2 ?Uri
是这样做的,还是我需要回退到字符串?顺便说一句,我尝试在几乎所有地方添加前导/尾随斜线.
Unexpectedly, uri2
is http://localhost/2. How would I append to uri1
so it's http://localhost/1/2 intead? Does Uri
do this, or do I need to fallback to strings? Incidentally, I've tried adding leading/trailing slashes almost everywhere.
推荐答案
"1" 和 "2" 是 url 的文件名部分".如果你让1"看起来更像目录路径,它会正常工作1/":
"1" and "2" are "file name portion" of a url. If you make "1" to look more like directory path it will work ok "1/":
var baseUri = new Uri("http://localhost/");
var uri1 = new Uri(baseUri, "1/");
var uri2 = new Uri(uri1, "2");
注意:文件名部分"不是一个真正的术语,因为Url只有路径"和查询"组件,但通常路径的最后一块被视为文件名:/foo/bar/file.txt".文本".
Note: "file name portion" is not a real term, as Url only have "path" and "query" component, but normally last chunk of a path is treated as file name: "/foo/bar/file.txt".
当您组合 2 条路径时,您想用第二条路径替换第一条路径的某些尾部.在你的情况下,它最终只有文件名"段:/1"和2"(如果你把像/myFile.txt"和NewFile.txt"这样的真实值组合起来会更容易看看它为什么会这样).
When you combine 2 path you want to replace some tail portion of the first path with the second one. In your case it ends up to have just "file name" segment for both :"/1" and "2" (if you put real value like "/myFile.txt" and "NewFile.txt" in combining it would be easier to see why it behaves this way).
