New in v1.0.1

• Retarget to .NET Core 2.0 and .NET Framework 4.5.2

Score Computation

• If one string is null/empty and the other is not, the score is 0
• If both strings are null/empty, the score is 1
• Otherwise, a length score is multiplied by a character match score, where length score = (min / max) and character match score is (num matching / total)

Example

Refer to the Test project for an example.

using Similarity;

Console.Write("String 1 : ");
string str1 = Console.ReadLine(); 
Console.Write("String 2 : ");
string str2 = Console.ReadLine();
Console.WriteLine("Score    : " + StringSimilarity.Calculate(str1, str2));
