How Can I Correctly Parse Culture-Specific Date Strings in C#?

Use a specific cultural format to analyze the string as the date

Question statement:

Try to use the method as the date string of the "DD/MM/YYYY" format into a

object, which will cause abnormalities. It is prompted that the "string is not recognized as effective DateTime format".

Parse Explanation and solution: DateTime

When parsing the string of the custom format, the current cultural format is set. In this example, the string represents the European date format, which is different from the default American format. To solve this problem, please use the method.

Method accept three parameters: the string to be parsed, the expected format and format provider. The format provider specifies the special format rules to be applied to the cultural format. For a given example:

Parse The as a format provider will default to the setting of the current culture. Alternatively, you can specify a specific regional characteristics, such as: ParseExact

The difference between the PARSE and PARSEEXACT: ParseExact

this.Text = "22/11/2009";
DateTime date = DateTime.ParseExact(this.Text, "dd/MM/yyyy", null);

Parse: null Assume that the current culture format settings are assumed, and the limited date format set is supported.

DateTime date = DateTime.ParseExact(this.Text, "dd/MM/yyyy", CultureInfo.GetCultureInfo("en-GB"));

PARSEEEXACT:

Need to be explicitly format, and allow more flexible customized analysis processes.

Select the best answer aspect:

• Type safety: Both answers provide type security, because the result of the parsing is effective
object.
• Performance: The performance of both methods is similar, because they both involve the resolution of the string as the date indicating the form.

Flexibility:

It provides greater flexibility by allowing custom target formats to make it more suitable for handling dates with non -standard formats or different cultures.
