Regex for .NET Application

I need a regex expression that can evaluate a string, to be used in a .NET application. You'll need to check for 9 conditions: 1. All Alphabetical Characters in the entire string are Upper Case Example: THIS IS A NAME Example: THIS 132 ... IT Example: NAMEHERE 2. Underscores are present Example: _Name Example: Name_Surname_Street Example: City_ Example: Hello__Bye 3. String starts with numeric character Example: 1 Name Example: 1Name Example: 411 Name Example: 4325Name 4. String contains the character ‘V’ (case insensitive) followed by a numeric character Example: v101 Name Example: Name v13 Example: Namev24 5. First or Last characters in string contain "DEV" or "TEST" or "UAT" (case insensitive) Example: Name Dev Example: Name TEST Example: Nameuat Example: Test Name Example: dev1name Do not filter out if the substring is in the middle: Name test Surname 6. String contains no spaces and has a mix of alphabetical and numerical characters Example: 12345Name Example: name3739 7. String contains no spaces and has a mix of more than one subsequent uppercase characters and more than one subsequent lowercase characters. Example: ABCNameSurname Example: nameSURNAME 8. No spaces CamelCase Example: NameSurname Example: NamesurnameCityCountry 9. Contains substring with more than 5 subsequent uppercase characters Example: nameSURNAME Example: SURNAMEname Example: nameSURNAMEcountry I want to integrate this in a .NET application to evaluate 100's of strings. For each string I want to know which condition was met, or if none were met. For example, if I have 4 strings: - Name Dev - 1Name - THIS 132 ... IT - Name I want the outcome to be - 5 - 3 - 1 - 0 Where zero means no condition was met. If multiple conditions are met, I only need to know the first one (evaluate in order, 1 to 9) Your code must clearly be commented and break out the regex expressions into 9 distinct parts, rather than 1 big regex, so I can remove 1 of the conditions if I want to.
