Converts the specified string representation of a date and time to its DateTime equivalent and returns a value that indicates whether the conversion succeeded.

Overloads

TryParse(ReadOnlySpan<Char>, DateTime)	Converts the specified char span of a date and time to its DateTime equivalent and returns a value that indicates whether the conversion succeeded.
TryParse(String, DateTime)	Converts the specified string representation of a date and time to its DateTime equivalent and returns a value that indicates whether the conversion succeeded.
TryParse(ReadOnlySpan<Char>, IFormatProvider, DateTime)	Tries to parse a span of characters into a value.
TryParse(String, IFormatProvider, DateTime)	Tries to parse a string into a value.
TryParse(String, IFormatProvider, DateTimeStyles, DateTime)	Converts the specified string representation of a date and time to its DateTime equivalent using the specified culture-specific format information and formatting style, and returns a value that indicates whether the conversion succeeded.
TryParse(ReadOnlySpan<Char>, IFormatProvider, DateTimeStyles, DateTime)	Converts the span representation of a date and time to its DateTime equivalent using the specified culture-specific format information and formatting style, and returns a value that indicates whether the conversion succeeded.

Remarks

Important

Eras in the Japanese calendars are based on the emperor's reign and are therefore expected to change. For example, May 1, 2019 marked the beginning of the Reiwa era in the JapaneseCalendar and JapaneseLunisolarCalendar. Such a change of era affects all applications that use these calendars. For more information and to determine whether your applications are affected, see Handling a new era in the Japanese calendar in .NET. For information on testing your applications on Windows systems to ensure their readiness for the era change, see Prepare your application for the Japanese era change. For features in .NET that support calendars with multiple eras and for best practices when working with calendars that support multiple eras, see Working with eras.

TryParse(ReadOnlySpan<Char>, DateTime)

Source:: DateTime.cs

Source:: DateTime.cs

Source:: DateTime.cs

Converts the specified char span of a date and time to its DateTime equivalent and returns a value that indicates whether the conversion succeeded.

public:
 static bool TryParse(ReadOnlySpan<char> s, [Runtime::InteropServices::Out] DateTime % result);

public static bool TryParse (ReadOnlySpan<char> s, out DateTime result);

static member TryParse : ReadOnlySpan<char> * DateTime -> bool

Public Shared Function TryParse (s As ReadOnlySpan(Of Char), ByRef result As DateTime) As Boolean

Parameters

s: ReadOnlySpan<Char>

A string containing a date and time to convert.

result: DateTime

When this method returns, contains the DateTime value equivalent to the date and time contained in s, if the conversion succeeded, or DateTime.MinValue if the conversion failed. The conversion fails if the s parameter is null, is an empty string (""), or does not contain a valid string representation of a date and time. This parameter is passed uninitialized.

Returns

Boolean

true if the s parameter was converted successfully; otherwise, false.

Remarks

The DateTime.TryParse(String, DateTime) method is similar to the DateTime.Parse(String) method, except that the TryParse(String, DateTime) method does not throw an exception if the conversion fails.

The string s is parsed using formatting information in the current DateTimeFormatInfo object, which is supplied implicitly by the current culture.

This method tries to ignore unrecognized data, if possible, and fills in missing month, day, and year information with the current date. If s contains only a date and no time, this method assumes the time is 12:00 midnight. If s includes a date component with a two-digit year, it is converted to a year in the current culture's current calendar based on the value of the Calendar.TwoDigitYearMax property. Any leading, inner, or trailing white space character in s is ignored. The date and time can be bracketed with a pair of leading and trailing NUMBER SIGN characters ('#', U+0023), and can be trailed with one or more NULL characters (U+0000).

Because the DateTime.TryParse(String, DateTime) method tries to parse the string representation of a date and time using the formatting rules of the current culture, trying to parse a particular string across different cultures can either fail or return different results. If a specific date and time format will be parsed across different locales, use the DateTime.TryParse(String, IFormatProvider, DateTimeStyles, DateTime) method or one of the overloads of the TryParseExact method and provide a format specifier.

If s is the string representation of a leap day in a leap year in the current calendar, the method parses s successfully. If s is the string representation of a leap day in a non-leap year in the current culture's current calendar, the parse operation fails and the method returns false.

If s contains no time zone information, result contains a DateTime value whose Kind property is DateTimeKind.Unspecified when the method returns. If the string to be parsed contains time zone information, result contains a DateTime value whose Kind property is DateTimeKind.Local when the method returns.

Notes to Callers

Formatting is influenced by properties of the current DateTimeFormatInfo object, which by default are derived from the Regional and Language Options item in Control Panel. The TryParse method can unexpectedly fail and return False if the current DateSeparator and TimeSeparator properties are set to the same value.

Returns

Boolean

true if the s parameter was converted successfully; otherwise, false.

Exceptions

ArgumentException

styles is not a valid DateTimeStyles value.

-or-

styles contains an invalid combination of DateTimeStyles values (for example, both AssumeLocal and AssumeUniversal).

NotSupportedException

provider is a neutral culture and cannot be used in a parsing operation.

Notes to Callers

Formatting is influenced by properties of the current DateTimeFormatInfo object, which is supplied by the provider parameter. The TryParse method can unexpectedly fail and return False if the current DateSeparator and TimeSeparator properties are set to the same value.

Applies to

TryParse(ReadOnlySpan<Char>, IFormatProvider, DateTimeStyles, DateTime)

Source:: DateTime.cs

Source:: DateTime.cs

Source:: DateTime.cs

Converts the span representation of a date and time to its DateTime equivalent using the specified culture-specific format information and formatting style, and returns a value that indicates whether the conversion succeeded.

public:
 static bool TryParse(ReadOnlySpan<char> s, IFormatProvider ^ provider, System::Globalization::DateTimeStyles styles, [Runtime::InteropServices::Out] DateTime % result);

public static bool TryParse (ReadOnlySpan<char> s, IFormatProvider? provider, System.Globalization.DateTimeStyles styles, out DateTime result);

public static bool TryParse (ReadOnlySpan<char> s, IFormatProvider provider, System.Globalization.DateTimeStyles styles, out DateTime result);

static member TryParse : ReadOnlySpan<char> * IFormatProvider * System.Globalization.DateTimeStyles * DateTime -> bool

Public Shared Function TryParse (s As ReadOnlySpan(Of Char), provider As IFormatProvider, styles As DateTimeStyles, ByRef result As DateTime) As Boolean

Parameters

s: ReadOnlySpan<Char>

A span containing the characters representing the date and time to convert.

provider: IFormatProvider

An object that supplies culture-specific formatting information about s.

styles: DateTimeStyles

A bitwise combination of enumeration values that defines how to interpret the parsed date in relation to the current time zone or the current date. A typical value to specify is None.

result: DateTime

Returns

Boolean

true if the s parameter was converted successfully; otherwise, false.
