i want to check whether a variable contains date or not

public static bool IsDate(string stringToTest)


		{


			System.DateTime datTest = System.DateTime.Now;


			


			bool bRtn = false;


			


			try { 


				datTest = System.Convert.ToDateTime(stringToTest.ToString());


				bRtn = true;


			}


			catch(Exception exe) { bRtn = false ; }


			return bRtn;


		}

if I pass 4.42 to IsDate() then exception occurs and it is returning false (that is what expected)

but if I pass 5.09 to IsDate() then it is returning true (internally 5.09 getting converted to 5/9/2004)


does anybody know how to solve this problem?

I thought that converting value to Double might help

please help me out of this..........

for your information
I am new to c#
I know VB.net well

thanx in advance

You could try using DateTime.Parse or DateTime.ParseExact and passing in the format of the date that you want to check for
