C# TimeSpan TryParseExact(String, String[], IFormatProvider, TimeSpanStyles, TimeSpan) Array

Description

TimeSpan TryParseExact(String, String[], IFormatProvider, TimeSpanStyles, TimeSpan) converts the specified string representation of a time interval to its TimeSpan equivalent by using the specified formats, culture-specific format information, and styles, and returns a value that indicates whether the conversion succeeded. The format of the string representation must match one of the specified formats exactly.

Syntax

TimeSpan.TryParseExact(String, String[], IFormatProvider, TimeSpanStyles, TimeSpan) has the following syntax.

public static bool TryParseExact(
  string input,//from  w  w  w  .ja  v  a 2  s.  c  o m
  string[] formats,
  IFormatProvider formatProvider,
  TimeSpanStyles styles,
  out TimeSpan result
)

Parameters

TimeSpan.TryParseExact(String, String[], IFormatProvider, TimeSpanStyles, TimeSpan) has the following parameters.

• input - A string that specifies the time interval to convert.
• formats - A array of standard or custom format strings that define the acceptable formats of input.
• formatProvider - An object that supplies culture-specific formatting information.
• styles - One or more enumeration values that indicate the style of input.
• result - When this method returns, contains an object that represents the time interval specified by input, or TimeSpan.Zero if the conversion failed. This parameter is passed uninitialized.

Returns

TimeSpan.TryParseExact(String, String[], IFormatProvider, TimeSpanStyles, TimeSpan) method returns true if input was converted successfully; otherwise, false.

Example

The following example calls the TryParseExact(String, String[], IFormatProvider, TimeSpanStyles, TimeSpan) method to convert each element of a string array to a TimeSpan value.

using System;/*from   ww w. j  a va2  s. c  om*/
using System.Globalization;

public class Example
{
   public static void Main()
   {
      string[] inputs = { "3", "16:42", "1:6:52:35.0625", 
                          "1:6:52:35,0625" }; 
      string[] formats = { "%h", "g", "G" };
      TimeSpan interval;
      CultureInfo culture = new CultureInfo("fr-FR");

      // Parse each string in inputs using formats and the fr-FR culture. 
      foreach (string input in inputs) {
         if(TimeSpan.TryParseExact(input, formats, culture, 
                                   TimeSpanStyles.AssumeNegative, out interval))
            Console.WriteLine("{0} --> {1:c}", input, interval);
         else
            Console.WriteLine("Unable to parse {0}", input);   
      }
   }
}

The code above generates the following result.
