1. You have to check that the datetime string is a valid one using TryParse method;
2. If it is a valid datetime string, then do the conversion to datetime else abort.

C#

using System;

public class Program
{
    public static void Main()
    {
          string dateString = "27/04/2014 00:00:00 AM";

          Console.WriteLine("The original string is {0}", dateString);

          DateTime dt;

          if (DateTime.TryParse(dateString, out dt))
          {
               string format = "yyyy-MM-dd";
               // do something with dt

               Console.WriteLine(dt.ToString(format));
          }
          else
          {
              Console.WriteLine("Not a valid datetime");
          }
    }
}

Solution 1

It's getting error for datetime format because your string is in "dd/MM/yyyy" format

It will unable to convert datetime it needs like "MM/dd/yyyy" or "yyyy/MM/dd"
Hope so

Then you need to changes your string date="04/27/2014" like this

try this
string CrDate = Convert.ToDateTime("Your field").ToString();

Solution 3

The exception was raised by the database, not by ASP.Net. You tried to insert or update a datatime value, or tried to retrieve rows based on a datetime constraint (WHERE clause). I further conclude that you generated the SQL query by string concatenation, instead of using a parameterized query.
And that's the point: use a parameterized query. Beyond those annoying formatting issues, it will provide a good protection from SQL Injection attacks (a really important security issue)!
