什么是Uri.ToString（）和Uri.AbsoluteUri之间的区别？ [英] What's the difference between Uri.ToString() and Uri.AbsoluteUri?

问题描述

作为注释到Azure的问题，就在刚才，@smarx指出

As a comment to an Azure question just now, @smarx noted

我认为这是一般好做blob.Uri.AbsoluteUri比   blob.Uri.ToString（）。

I think it's generally better to do blob.Uri.AbsoluteUri than blob.Uri.ToString().

有没有道理呢？该文档 Uri.AbsoluteUri 指出，它获取绝对URI， Uri.ToString（）获取规范的字符串重新presentation指定实例。

Is there a reason for this? The documentation for Uri.AbsoluteUri notes that it "Gets the absolute URI", Uri.ToString() "Gets a canonical string representation for the specified instance."

推荐答案

鉴于例如：

UriBuilder builder = new UriBuilder("http://somehost/somepath");
builder.Query = "somekey=" + HttpUtility.UrlEncode("some+value");
Uri someUri = builder.Uri;

在这种情况下， Uri.ToString（）将返回一个人类可读的网址：<一href="http://somehost/somepath?somekey=some+value">http://somehost/somepath?somekey=some+value

In this case, Uri.ToString() will return a human-readable URL: http://somehost/somepath?somekey=some+value

Uri.AbsoluteUri ，另一方面将返回EN codeD形式HttpUtility.UrlEn code还给了： HTTP ：//，某/ somepath somekey =某些％2bvalue

Uri.AbsoluteUri on the other hand will return the encoded form as HttpUtility.UrlEncode returned it: http://somehost/somepath?somekey=some%2bvalue
