convert a string to date time in csharp

To convert a string to a DateTime object in C#, you can use the DateTime.Parse or DateTime.ParseExact method.

Here is an example using DateTime.Parse:

main.cs
string dateString = "2021-01-01 10:30";
DateTime dateTime = DateTime.Parse(dateString);
88 chars
3 lines

And here is an example using DateTime.ParseExact, which allows you to specify the exact format of the input string:

main.cs
string dateString = "01/01/2021 10:30 AM";
DateTime dateTime = DateTime.ParseExact(dateString, "MM/dd/yyyy hh:mm tt", CultureInfo.InvariantCulture);
149 chars
3 lines

In both cases, the resulting dateTime object will contain the parsed value from the string.

Note that if the string is in a different format or contains invalid characters, an exception will be thrown. To handle this, you can use the DateTime.TryParse or DateTime.TryParseExact methods, which return a boolean indicating whether the conversion was successful, and store the result in an out parameter:

main.cs
string dateString = "2021-01-01 10:30";
DateTime dateTime;

if (DateTime.TryParse(dateString, out dateTime))
{
    // Conversion succeeded, dateTime contains the parsed value
}
else
{
    // Conversion failed, handle the error
}
229 chars
12 lines

These methods give you more flexibility when dealing with different date and time formats.
