Return Values for the CStr Function
The following table describes the return values for CStr for different data types of expression.
| If expression type is | CStr returns |
|---|---|
| A string containing "True" or "False". | |
| A string containing a Date value (date and time) in the short date format of your system. | |
| A string representing the number. |
The Date type always contains both date and time information. For purposes of type conversion, Visual Basic considers 1/1/0001 (January 1 of the year 1) to be a neutral value for the date, and 00:00:00 (midnight) to be a neutral value for the time. CStr does not include neutral values in the resulting string. For example, if you convert #January 1, 0001 9:30:00# to a string, the result is "9:30:00 AM"; the date information is suppressed. However, the date information is still present in the original Date value and can be recovered with functions such as DatePart Function (Visual Basic).

| The CStr function performs its conversion based on the current culture settings for the application. To get the string representation of a number in a particular culture, use the number's ToString(IFormatProvider) method. For example, use System.Double.ToString(System.IFormatProvider) when converting a value of type Double to a String. |
