c# - Convert fullwidth to halfwidth -

in c#, how convert string that's using fullwidth form characters halfwidth form characters?

for example, given userinput below, want convert Ｓｔａｃｋｏｖｅｒｆｌｏｗ stackoverflow:

string userinput= "Ｓｔａｃｋｏｖｅｒｆｌｏｗ"; //string userinput= "stackoverflow"; 

you can use string.normalize() method:

string userinput = "Ｓｔａｃｋｏｖｅｒｆｌｏｗ"; string result = userinput.normalize(normalizationform.formkc); //result = "stackoverflow" 

see example on dotnetfiddle.

more information on normalization forms can found on unicode.org.
