# NumberFormatInfo.NumberNegativePattern Property

## Definition

Gets or sets the format pattern for negative numeric values.

``````public:
property int NumberNegativePattern { int get(); void set(int value); };``````
``public int NumberNegativePattern { get; set; }``
``member this.NumberNegativePattern : int with get, set``
``Public Property NumberNegativePattern As Integer``

#### Property Value

The format pattern for negative numeric values.

#### Exceptions

The property is being set to a value that is less than 0 or greater than 4.

The property is being set and the NumberFormatInfo object is read-only.

## Examples

The following example displays a value using different NumberNegativePattern patterns.

``````using namespace System;
using namespace System::Globalization;

int main()
{
// Create a new NumberFormatinfo.
NumberFormatInfo^ nfi = gcnew NumberFormatInfo;

// Takes a negative value.
Int64 value = -1234;

// Displays the value with default formatting.
Console::WriteLine("{0,-20} {1,-10}", "Default:",
value.ToString("N", nfi));

// Displays the value with other patterns.
for (int i = 0; i <= 4; i++) {
nfi->NumberNegativePattern = i;
Console::WriteLine("{0,-20} {1,-10}",
String::Format("Pattern {0}:",
nfi->NumberNegativePattern),
value.ToString("N", nfi));
}
}
// The example displays the following output:
//       Default:             -1,234.00
//       Pattern 0:           (1,234.00)
//       Pattern 1:           -1,234.00
//       Pattern 2:           - 1,234.00
//       Pattern 3:           1,234.00-
//       Pattern 4:           1,234.00 -

string.Format("Pattern {0}:",
nfi.NumberNegativePattern),
value.ToString("N", nfi));
}
}

## Remarks

The NumberNegativePattern property defines the format of negative values formatted with the "N" standard numeric format string. This property has one of the values in the following table. The symbol "-" is the NegativeSign and `n` is a number.

Value Associated pattern
0 (n)
1 -n
2 - n
3 n-
4 n -

The default value for the invariant culture returned by the InvariantInfo property is 1, which represents "-n", where n is a number.
