How to remove all non alphanumeric characters from a string except dash in C#?

To remove all non-alphanumeric characters from a string in C# except the dash character, you can use a regular expression and the Regex.Replace method. Here's an example:

 using System.Text.RegularExpressions; string input = "abc-123#def$456"; // Remove all non-alphanumeric characters except dash string output = Regex.Replace(input, "[^a-zA-Z0-9-]", ""); Console.WriteLine(output); // Output: "abc-123def456"

In this example, we have a string input that contains a mix of alphanumeric and non-alphanumeric characters, including the dash character (-).

We use the Regex.Replace method to replace all non-alphanumeric characters except the dash with an empty string. The regular expression [^a-zA-Z0-9-] matches any character that is not an uppercase or lowercase letter or a digit or a dash.

The result is a string output that contains only the alphanumeric characters and the dash character.
