Change Date into Month Name and Date with Year in C#

Question

I want to convert the date into something different. I give input date, it will convert into that format.

My code

 var dt = erd.StartDate.Value.ToShortDateString();

 var format = String.Format("{MMM/D/yyyy}", dt);

Here it is showing an error like input string is not correct format.

Help me to find out the issue?

Answer 1

Simply rewrite it like this (I'm assuming the erd.StartDate.Value datatype is datetime)

string result = erd.StartDate.Value.ToString("MMM/dd/yyyy");

or using "D" is equivalent to "dddd, MMMM d, yyyy"

string result = erd.StartDate.Value.ToString("D");

Answer 2

1. you need to use small d for representing Date.
2. you should not convert the Date into String before applying the custom Format.

Try This:

var dt = erd.StartDate.Value;
var format =dt.ToString("MMM/d/yyyy");

Answer 3

To solve your error, try the below code:

var dt = erd.StartDate.Value;

var format = String.Format("{0:MMMM/dd/yyyy}", dt);

You need to specify the parameter index to use. In the above code, we are telling String.Format to use parameter 0 to be formatted as a DateTime.

DateTime formatting has many types. Please see here for the different things you can do.
