新问题是HttpUtilities.UrlEncode()方法将空格()转换为plusses()而不是像浏览器想要的那样.因此,文件图像name.jpg被正确找到时,文件图像name.jpg将返回not-found.
值得庆幸的是,一位同事向我指出了HttpUtilities.UrlPathEncode(),它用于代替空格.
为什么有两种处理Url编码的方法？为什么有两个命令行为如此不同？
解决方法
UrlPathEncode只是替换了URL中无法使用的所有字符,例如<,>和.
两条MSDN链接都包含此引用：
You can encode a URL using with the UrlEncode method or the UrlPathEncode method. However,the methods return different results. The UrlEncode method converts each space character to a plus character (+). The UrlPathEncode method converts each space character into the string “%20”,which represents a space in hexadecimal notation. Use the UrlPathEncode method when you encode the path portion of a URL in order to guarantee a consistent decoded URL,regardless of which platform or browser performs the decoding.
