The HostProtectionAttribute attribute applied to this class has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

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, typeof(string))); 

double myDoub = 100.55;
String myDoStr = "4000.425";
    ConvertTo((System.Double)myDoub, String.class.ToType()));

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