System.Globalization Namespace   NumberFormatInfo Class

---

Sets or retrieves the string to use as the decimal separator in numeric values.

[ VB ]
public Property NumberDecimalSeparator As String

[ C# ]
public string NumberDecimalSeparator {get; set;}

[ C++ ]
public: __property String* get_NumberDecimalSeparator ( );
public: __property void set_NumberDecimalSeparator ( String* );

[ JScript ]
function get NumberDecimalSeparator ( ) : String;
public function set NumberDecimalSeparator ( String );

The string to use as the decimal separator in numeric values. The default for InvariantInfo is '.'.

Exception Type	Condition
ArgumentNullException	The property is being set to a null reference ( Nothing in Visual Basic ).
ArgumentException	The property is being set to a value that is the same as NumberGroupSeparator, CurrencyGroupSeparator, or PercentGroupSeparator.
InvalidOperationException	The property is being set and the NumberFormatInfo is read-only.

The initial value of this property is derived from the settings in Regional and Language Options ( or Regional Options or Regional Settings ) in Control Panel. However, if any of the group separators ( NumberGroupSeparator, CurrencyGroupSeparator, or PercentGroupSeparator ) is the same as any of the decimal separators ( NumberDecimalSeparator, CurrencyDecimalSeparator, or PercentDecimalSeparator ), parsing ambiguous strings produces unpredictable results. If you explicitly set any of the group separator properties in NumberFormatInfo to a value that is the same as any of the decimal separators or if you explicitly set any of the decimal separators to a value that is the same as any of the group separators, ArgumentException is thrown.

The below shows the NumberDecimalSeparator used for each of the available cultures.
