TimeSpan.ToString Method (String)
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Converts the value of the current TimeSpan object to its equivalent string representation by using the specified format.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
Public Function ToString ( _
format As String _
) As String
public string ToString(
string format
)
Parameters
- format
Type: System..::.String
A standard or custom TimeSpan format string.
Return Value
Type: System..::.String
The string representation of the current TimeSpan value in the format specified by the format parameter.
Exceptions
| Exception | Condition |
|---|---|
| FormatException | The format parameter is not recognized or is not supported. |
Remarks
The format parameter can be any valid standard or custom format specifier for TimeSpan values. If format is equal to String..::.Empty or is nullNothingnullptra null reference (Nothing in Visual Basic), the return value of the current TimeSpan object is formatted with the common format specifier ("c"). If format is any other value, the method throws a FormatException.
The format of the returned string is defined by the formatting conventions of the current culture.
The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics:
For more information about format strings for TimeSpan values, see Standard TimeSpan Format Strings and Custom TimeSpan Format Strings.
For more information about support for formatting in the .NET Framework, see Formatting Types.
Examples
The following example uses standard TimeSpan format strings to display the string representation of each element in an array of TimeSpan values
Module Example
Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
Dim spans() As TimeSpan = { TimeSpan.Zero, New TimeSpan(-14, 0, 0, 0, 0),
New TimeSpan(1, 2, 3),
New TimeSpan(0, 0, 0, 0, 250),
New TimeSpan(99, 23, 59, 59, 999),
New TimeSpan(3, 0, 0),
New TimeSpan(0, 0, 0, 0, 25) }
Dim fmts() As String = {"c", "g", "G", "hh\:mm\:ss", "%m' min.'" }
For Each span As TimeSpan In spans
For Each fmt As String In fmts
outputBlock.Text += String.Format("{0}: {1}", fmt, span.ToString(fmt)) & vbCrLf
Next
outputBlock.Text &= vbCrLf
Next
End Sub
End Module
