Question

我正在尝试使用byte []变量读取长字符串，但它给出了以下错误：

{System.IO.PathTooLongException：指定的路径，文件名或两者都太长。完全限定的文件名必须少于260个字符，目录名必须少于248个字符。

任何人都可以帮忙，谢谢。

请查看以下代码。在第二行，我收到了上述错误。

string filename = "Ak8AdFf/gICvXL9Ls3fDVMlLk7WbnddtL6GsobiBzXVLs4SurY6vhsOuMIRduX+PYmY1TYRmh026PbZlw0TNU711pLXGdc1qNqusr7if2WreciqKMJixqceH5WgrcTR2O5NAuXa/l8apkcSd3VQ/dVm3YJ7HxNSp1LvXi+CFWoR5nlNpeIffueCo6Kl1b4JxgGWSeqiBj1qbSKVQs0KoU7tDxUetbDodIai69vd8jSAIIKCEKvXL6BBBBBBBBBBBBBBBBBBBAAAAAAAAAAAAAACCCAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA==";
byte[] bmpbyteArray = System.IO.File.ReadAllBytes(filename);

您误解了NODE EXPLANATION ---------------------------------------------------------------------- <%-- '<%--' ---------------------------------------------------------------------- ( group and capture to \1: ---------------------------------------------------------------------- (?: group, but do not capture (0 or more times (matching the least amount possible)): ---------------------------------------------------------------------- < '<' ---------------------------------------------------------------------- \/? '/' (optional (matching the most amount possible)) ---------------------------------------------------------------------- [a-z]+ any character of: 'a' to 'z' (1 or more times (matching the most amount possible)) ---------------------------------------------------------------------- (?= look ahead to see if there is: ---------------------------------------------------------------------- [\s>] any character of: whitespace (\n, \r, \t, \f, and " "), '>' ---------------------------------------------------------------------- ) end of look-ahead ---------------------------------------------------------------------- (?: group, but do not capture (0 or more times (matching the most amount possible)): ---------------------------------------------------------------------- [^>=] any character except: '>', '=' ---------------------------------------------------------------------- | OR ---------------------------------------------------------------------- = '=' ---------------------------------------------------------------------- (?: group, but do not capture: ---------------------------------------------------------------------- ' '\'' ---------------------------------------------------------------------- [^']* any character except: ''' (0 or more times (matching the most amount possible)) ---------------------------------------------------------------------- ' '\'' ---------------------------------------------------------------------- | OR ---------------------------------------------------------------------- " '"' ---------------------------------------------------------------------- [^"]* any character except: '"' (0 or more times (matching the most amount possible)) ---------------------------------------------------------------------- " '"' ---------------------------------------------------------------------- | OR ---------------------------------------------------------------------- [^'"\s]* any character except: ''', '"', whitespace (\n, \r, \t, \f, and " ") (0 or more times (matching the most amount possible)) ---------------------------------------------------------------------- ) end of grouping ---------------------------------------------------------------------- )* end of grouping ---------------------------------------------------------------------- \s? whitespace (\n, \r, \t, \f, and " ") (optional (matching the most amount possible)) ---------------------------------------------------------------------- \/?

File.ReadAllBytes()

参数是路径 TO 二进制文件，而不是二进制文件本身。因此，文件名不能超过特定的字符长度。

Answer 2

如果您没有阅读文件，则无需使用System.IO.File课程。您似乎只是想获取字符串的字节数组。您需要使用编码类，例如System.Text.Encoding

var bts = System.Text.Encoding.ASCII.GetBytes(filename.ToCharArray());

指定的路径，文件名或两者都太长
