String Comparison

String Comparison for C#.NET

Project Description

StringComparison is a library developed for reconciling naming conventions between different models of the electric grid. I have stripped off the power system specific code and put together what can effectively be used as a string extension for determining approximate equality between two strings. All of the algorithms used here have been pulled from online resources, translated into C#, and compiled into this library. I found several other similar open-source implementations around but nothing for .NET/C#. Adding the *.dll to your project will give you access to this extension and the individual extensions under the hood of the IsSimilarity() extension.

Algorithms included in this project

String Comparision

While all of the algorithms are exposed and can be used and can provide their raw results, they have been conveniently combined in a way that they can selectively be used to judge the approximate equality of two strings. This is done through the IsSimilar extension and by setting the desired StringComparisonOptions and StringComparisonTolerance.

For two strings that are desired to be compared approximately, a boolean response of equality can be garnered in the following way:


Download last release

or install from NuGet To install run the following command in the Package Manager Console

Install-Package StringComparison


string source = "behzad";
string target = "behsad";

var options = new List<StringComparisonOptions>();

// Choose which algorithms should weigh in for the comparison

// Choose the relative strength of the comparison - is it almost exactly equal? or is it just close?
var tolerance = StringComparisonTolerance.Strong;

// Get a boolean determination of approximate equality
bool result = source.IsSimilar(target, options, tolerance);
double howManySimilar = source.SimilarityPercent(target, options);
double simLevenshtein = 1 - source.LevenshteinDistancePercentage(target);
double simJaro = 1 - source.JaroDistance(target);
