C# .NET - i want to get date dd/MM/yyyy format but am getting dd-MM-yyyy format

Hi All,
i want to get date dd/MM/yyyy format but am getting dd-MM-yyyy format , i tried with 

var currentDate1 = DateTime.Now.ToString("dd/MM/yyyy");-- this also giving the data dd-MM-yyyy format.

2) and tried with another option

   System.Globalization.DateTimeFormatInfo MyDateTimeFormatInfo = new System.Globalization.DateTimeFormatInfo();
            MyDateTimeFormatInfo.ShortDatePattern = "M/d/yyyy";
            var StartDate = DateTime.Parse(dt.ToString("MM/dd/yyyy",MyDateTimeFormatInfo));

here am getting An exception of type 'System.FormatException' occurred in mscorlib.dll Error 

can anyone help me in this.

What is the current CultureInfo setting for the web app or application?  This would affect how .ToString renders the date.
