Convert Full Width to Half Width

Question

In C #, how do I convert a string that uses full-width shape characters to half-width shape characters?

For example, when using userInput below, I want to convert Ｓｔａｃｋｏｖｅｒｆｌｏｗ to Stackoverflow :

 string userInput= "Ｓｔａｃｋｏｖｅｒｆｌｏｗ"; //string userInput= "Stackoverflow";

You can use the string.Normalize() method:

 string userInput = "Ｓｔａｃｋｏｖｅｒｆｌｏｗ"; string result = userInput.Normalize(NormalizationForm.FormKC); //result = "Stackoverflow" 

See an example on DotNetFiddle .

Further information on normalization forms can be found at unicode.org .
