## 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.

```csharp

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));

```
