Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Remarks

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 Implementing a Type Converter.

Example

[Visual Basic, C#, C++] The following sample converts a variable of type Double to a string, and vice versa.

[Visual Basic] 
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))

[C#] 
double myDoub = 100.55;
string myDoStr = "4000.425";
Console.WriteLine(TypeDescriptor.GetConverter(myDoub).ConvertTo(myDoub, typeof(string))); 
Console.WriteLine(TypeDescriptor.GetConverter(myDoub).ConvertFrom(myDoStr));    

[C++] 
double myDoub( 100.55 );
String* myDoStr = S"4000.425";
Console::WriteLine(TypeDescriptor::GetConverter(__box(myDoub))->ConvertTo(__box(myDoub), __typeof(String)));
Console::WriteLine(TypeDescriptor::GetConverter(__box(myDoub))->ConvertFrom(myDoStr));
