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]

2.1

For 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.
