Windows 上 FileVersionInfo.FileVersion 字符串的最大可能长度

Question

我想将版本存储在数据库表中，不想使用varchar(max)它。我想要固定的东西varchar(xxx)

你能告诉我，FileVersionInfo.FileVersionWindows 平台上的最大可能长度是多少？

实际上想出了如何获得正确的版本：

var ver = FileVersionInfo.GetVersionInfo("D:\\oraociei11.dll").FileVersion;

这将返回 Oracle 库：

要以正确的方式获取文件版本：

var versionInfo = FileVersionInfo.GetVersionInfo("D:\\oraociei11.dll");
var properVersion = string.Format("{0}.{1}.{2}.{3}", versionInfo.FileMajorPart, versionInfo.FileMinorPart, versionInfo.FileBuildPart, versionInfo.FilePrivatePart);

Answer 1

根据此链接，它是一个 64 位数字，分为 4 个，每个 16 位。

这应该意味着每个部分最多可以是 65535，因此格式化字符串的总长度可以是 65535.65535.65535.65535，总长度为 23 个字符。
