推荐答案

在定义文件名时尝试使用@或\转义序列.

Try using @ or \ escape sequences when you are defining the file name.

文件名很难可以包含:"，"*"或?".从客户端的角度来看，这不是文件而是URL，因此目录定界符为"/"(但是，如果URL是本地文件，则也接受"\").这怎么可能是个问题?

Abhinav正确地解释了您可以将任何这些字符放入字符串文字中.这是一个问题吗?如果是这样，请记住，实际上在任何情况下都不应在代码中使用硬编码的字符串常量，尤其是这是一个URL.

-SA

A file name hardly can contain ":", "*" or "?". From the client standpoint, this is not a file but URL, so the directory delimiter is "/" (however "\" is also accepted if the URL is a local file). How can this be a problem?

Abhinav correctly explained that you can put any of these characters in a string literal. Is this was a problem? If it was, remember that there is practically no situation when you should use hard-coded string constants in your code, especially it this is a URL.

—SA

签出 ^ ].
使用EscapeUriString方法准备一个未转义的URI字符串作为Uri构造函数的参数.

Check out Uri.EscapeUriString[^].
Use the EscapeUriString method to prepare an unescaped URI string to be a parameter to the Uri constructor.
