How to parse version range
Now we are making a solution that has to get the package reference. But the version of package reference is a range and the default version parser need input a version but not a version range. This post will tell you how to parse the version range string to reference version.
The format for reference version is like this
[2.1.0.293,3.0)
[1.1.0.34,2.0)
(1.1.0.34,2.0]
2.1For parse the reference version string, we should make some property.
public class ReferenceVersion
{
public ReferenceVersion(Version version)
{
Version = version;
MinVersion = version;
MaxVersion = version;
IsIncludeMaxVersion = true;
IsIncludeMinVersion = true;
}
public ReferenceVersion(Version minVersion, Version maxVersion, bool isIncludeMinVersion,
bool isIncludeMaxVersion)
{
Version = null;
MinVersion = minVersion;
MaxVersion = maxVersion;
IsIncludeMinVersion = isIncludeMinVersion;
IsIncludeMaxVersion = isIncludeMaxVersion;
}
public Version Version { get; }
public Version MinVersion { get; }
public Version MaxVersion { get; }
public bool IsIncludeMinVersion { get; }
public bool IsIncludeMaxVersion { get; }
}I will use regex to get the string and parse the string to version.
public static ReferenceVersion Parser(string str)
{
if (_regex == null)
{
_regex = new Regex(@"([(|\[])([\d|.]*),([\d|.]*)([)|\]])", RegexOptions.Compiled);
}
var res = _regex.Match(str);
if (res.Success)
{
var isIncludeMinVersion = res.Groups[1].Value;
var minVersion = res.Groups[2].Value;
var maxVersion = res.Groups[3].Value;
var isIncludeMaxVersion = res.Groups[4].Value;
return new ReferenceVersion
(
string.IsNullOrEmpty(minVersion) ? null : Version.Parse(minVersion),
string.IsNullOrEmpty(maxVersion) ? null : Version.Parse(maxVersion),
isIncludeMinVersion.Equals("["),
isIncludeMaxVersion.Equals("]")
);
}
return new ReferenceVersion(Version.Parse(str));
}
private static Regex _regex;We can get the reference version in the solution file and know the solution reference package.
