Tuple<T1, T2, T3, T4>.ToString Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Returns a string that represents the value of this Tuple<T1, T2, T3, T4> instance.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Overrides Function ToString As String

public override string ToString()

Return Value

Type: System.String
The string representation of this Tuple<T1, T2, T3, T4> object.

Remarks

The string returned by this method takes the form (Item1, Item2, Item3, Item4), where Item1, Item2, Item3, and Item4 represent the values of the Item1, Item2, Item3, and Item4 properties, respectively. If any of the property values is nulla null reference (Nothing in Visual Basic), it is represented as String.Empty.

Examples

The following example illustrates the ToString method. It displays the components of an array of 4-tuple objects that contain the name of a city, a month of the year, and the high and low average temperature for that month.

Module Example
   Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      Dim temperatures() = _
             { Tuple.Create("New York, NY", 4, 61, 43), _
               Tuple.Create("Chicago, IL", 2, 34, 18), _ 
               Tuple.Create("Newark, NJ", 4, 61, 43), _
               Tuple.Create("Boston, MA", 6, 77, 59), _
               Tuple.Create("Detroit, MI", 9, 74, 53), _
               Tuple.Create("Minneapolis, MN", 8, 81, 61) } 
      ' Display the array of 4-tuple objects.
      For Each temperature In temperatures
         outputBlock.Text &= temperature.ToString() & vbCrLf
      Next
   End Sub
End Module
' The example displays the following output:
'       (New York, NY, 4, 61, 43)
'       (Chicago, IL, 2, 34, 18)
'       (Newark, NJ, 4, 61, 43)
'       (Boston, MA, 6, 77, 59)
'       (Detroit, MI, 9, 74, 53)
'       (Minneapolis, MN, 8, 81, 61)

      // Display the array of 4-tuple objects.
      foreach (var temperature in temperatures)
         outputBlock.Text += temperature.ToString() + "\n";
