Implement a Generic Custom Validation Control


This Tip applies to Microsoft .NET Framework.
 
        using System;
	using System.Text.RegularExpressions;

	public class CustomValidations
	{
		public CustomValidations()
		{
		}


		/// <summary>
		/// 	This method is used for validating _
the string and returns
		/// 				true , if _
the string contains alphabets
		/// 				otherwise _
false.
		///	</summary>
		/// <param name="regExpression">
		/// 	string : Regular Expression to be _
checked
		/// </param>
		/// <param name="stringToCheck">
		/// 	string : string to be validated
		/// </param>
		/// <return>
		/// 	bool
		/// </return>
		public static bool isValid(string _
regExpression,string stringToCheck)


			return !(new Regex(regExpression)). _
IsMatch(stringToCheck);
		}

	}


Some Regular Expression I tried with :

is Alphabetic 	: 	[^a-zA-Z]
is ValidString	:	[\']
is ValidNumber	:	[^0-9\\-\\s\\)\\(]
is ValidEmail	:	[^a-zA-Z0-9\\\\_\\.\\@]
