无法将字符串识别为有效的DateTime（System.FormatException）？

Question

I am getting error as:

An exception of type 'System.FormatException' occurred in mscorlib.dll but was not handled in user code

Additional information: String was not recognized as a valid DateTime.

This is my code :

if (txtRefDate.Text != "")
{
    string[] splitdate = txtRefDate.Text.Split('-');
    string newdate = splitdate[1] + "-" + splitdate[0] + "-" + splitdate[2];
    DateTime Compdate = Convert.ToDateTime(newdate);//On this line i'm getting error
    string date = Compdate.ToString("yyyy-MM-dd");
    obj.RefrenceDate = Convert.ToDateTime(date);
}

I am using CalenderExtender on my textbox . I tried Parse and ParseExact , but it is not working. What am I doing wrong here?

Answer 1

DateTime Compdate;
if (!String.IsNullOrEmpty(txtRefDate.Text) && DateTime.TryParse(txtRefDate.Text, out Compdate))
{
    obj.RefrenceDate = Compdate.Date;
}

Also take a look at TryParseExact() , which allows you to supply more info about the expected format of your input.

And if this fails, start logging the string values that fail. We need to see examples of what didn't work.

Hmm you seem to be doing a lot of unnecessary steps to parse and set a DateTime

var textDate = "06-20-2018";

if (!string.IsNullOrEmpty(textDate))
{
    var parsedDate = DateTime.ParseExact(textDate, "MM-dd-yyyy", null);

    obj.RefrenceDate = parsedDate;
}
