      If you need to convert to or from a string representation of a value in a format other than the one specified by your locale, you cannot use the Visual Basic type conversion functions. To do this, use the `ToString(IFormatProvider)` and `Parse(String, IFormatProvider)` methods of that value's type. For example, use <xref:System.Double.Parse%2A?displayProperty=nameWithType> when converting a string to a `Double`, and use <xref:System.Double.ToString%2A?displayProperty=nameWithType> when converting a value of type `Double` to a string.

 You should never write code that relies on equivalent numeric values for `True` and `False`.

 The [String Data Type](../../../language-reference/data-types/string-data-type.md) participates in very few widening conversions. `String` widens only to itself and `Object`, and only `Char` and `Char()` (a `Char` array) widen to `String`.
