The following code example converts a variable of type Double to a string, and vice versa.
double myDoub(100.55);
String^ myDoStr = "4000.425";
Console::WriteLine( TypeDescriptor::GetConverter( myDoub )->ConvertTo( myDoub, String::typeid ) );
Console::WriteLine( TypeDescriptor::GetConverter( myDoub )->ConvertFrom( myDoStr ) );
double myDoub = 100.55;
string myDoStr = "4000.425";
Console.WriteLine(TypeDescriptor.GetConverter(myDoub).ConvertTo(myDoub, typeof(string)));
Console.WriteLine(TypeDescriptor.GetConverter(myDoub).ConvertFrom(myDoStr));
Dim myDoub As Double = 100.55
Dim myDoStr As String = "4000.425"
Console.WriteLine(TypeDescriptor.GetConverter(myDoub).ConvertTo(myDoub, GetType(String)))
Console.WriteLine(TypeDescriptor.GetConverter(myDoub).ConvertFrom(myDoStr))
This converter can only convert a Double object to and from a string.
Note
You should never create an instance of DoubleConverter. Instead, call the GetConverter method of TypeDescriptor. For more information, see the examples in the TypeConverter base class.
For more information about type converters, see the TypeConverter base class and How to: Implement a Type Converter.
