Question

I have a string replace problem. I have a result like:

"Animal.Active = 1 And Animal.Gender = 2"

I want to replace something in this text.

Animal.Active part is returned from a database and sometimes it is returned with the Animal.Gender part.

When Animal.Gender part comes from the database I have to remove this And Animal.Gender part.

Also if the string has Animal.Active = 1, I have to remove Animal.Active = 1 And part. Note the And.

How can I do this?

Answer 1

You will need to use a regular expression (regex) to replace this, then, since you want to match a number.

  string pattern = "And Animal\.Gender\s*=\s*[0-9]+";
  string replacement = "";
  Regex rgx = new Regex(pattern);
  string result = rgx.Replace(input, replacement);

Will work to replace "And Animal.Gender = #" with zero or more white spaces between the = sign.

You can do a similar replacement for the second request, with Animal.Active.
